Depending on factors such as the function of the display device and the type of operating system, the number of levels and specific level types contained in the operating system may be expressed in other forms.

[0121] Usually, when viewing target applications related to media content through display devices such as TV devices, when viewing these media contents, usually the electronic media contents built into the display device when the display device leaves the factory are viewed. If other media contents need to be viewed, only the authorized media contents provided can be downloaded and viewed from the specified address, which seriously affects the viewing efficiency and the user experience. Moreover, with the continuous increase in user needs, there is also a need to generate user-defined media contents.

[0122] After research, it is found that current display devices usually have the functions of networking and interacting with users. Taking the display device as a television device as an example, a smart TV can be connected to the Internet so that the text content provided by the user can be obtained through the television device, and the text content can be submitted to the background server to generate new media content and then stored locally on the display device to generate customized media content. In the process of using the display device, after starting the target application, the list of generated media content can be displayed on the homepage of the target application, and when there is an unfinished task of generating media content when the target application was started last time, a media content generation task query request can be sent to the server to query and obtain the progress of the unfinished media content generation task, and when receiving the information that the media content generation is completed, the generated media content is downloaded from the server through the communication device, so that the generation of media content that was not generated when the target application was started last time can be realized imperceptibly by starting the target application, which can help improve the efficiency of media content generation, realize real-time update of the list of generated media content, and improve user experience.

[0123] The display device in some embodiments of the present application refers to Figure 5 As shown, it includes: a display 260, a communication device 220 and a controller 250, and the display 260, the communication device 220 and the controller 250 are communicatively connected.

[0124] Understandably, Figure 5 The examples shown are merely examples of some components included in the display device and do not constitute a limitation on the components included in the display device of this embodiment.

[0125] based on Figure 5 The display device shown, in some embodiments:

[0126] a display 260 configured to display a graphical user interface;

[0127] The communication device 220 is configured to establish a communication connection with the server;

[0128] The controller 250 is configured to display a device homepage, and when the device homepage receives an operation of selecting a target application, start the target application, switch to display the target application homepage, the first display area of ​​the target application homepage displays a list of generated media contents, and the focus of the display device is located on a media content in the list of generated media contents;

[0129] The controller 250 is also configured to, upon receiving an operation to select a target application, send a media content generation task query request to the server via the communication device 260 if there is an unfinished media content generation task, and upon receiving information that the media content generation is completed, download the generated media content from the server via the communication device 260 and update the list of generated media content.

[0130] The device homepage is a page displayed after the display device is turned on. For example, if the display device is a TV device, the device homepage is the TV device homepage.

[0131] The target application is a functional application that can view generated media content and generate customized media content based on text content input by the user. The media content in the target application can include pictures, text, audio, etc. The pictures and audio are all related to the content text. A picture can contain corresponding text content or be superimposed with corresponding text content, and a picture corresponds to audio content. When playing media content, the playback time of the picture and content text corresponds to the broadcast time of the audio content corresponding to the picture.

[0132] In some possible embodiments, a video file may be formed by using the text content and content audio corresponding to each of the multiple pictures, wherein the video file includes multiple sub-video contents, the duration of each sub-video content is the same as the duration of a content audio, and each frame of the picture and the text content in the picture in each sub-video content may be the same. Each sub-video content in the video file may be played continuously, or may be played by switching to the previous sub-video content or the next sub-video content in response to an instruction.

[0133] Starting the target application refers to loading the program of the target application so that the target application is in a running state.

[0134] The type of the target application is not limited. In some embodiments, the target application may be an application related to viewing picture books.

[0135] The display name of the target application on the device homepage is not limited. Taking the target application as a picture book application as an example, some possible display names may be, for example, picture book, AI picture book, smart fairy tale, smart picture book, etc., but are not limited thereto.

[0136] The target application may be entered in various possible ways. In some embodiments, a Launcher module may be provided, and the target application may be started and entered by calling the Launcher module.

[0137] The first display area is an area in the homepage of the target application that is used to display the generated media content list. The range of the first display area is not limited. Figure 6Taking the target application homepage as an example, the first display area may be the area 601 below the target application homepage. The generated media content list refers to a list of customized media content that has been generated based on the text content input by the user, such as Figure 6 A list formed by media content 6011, media content 6012, and media content 6013.

[0138] Among them, in some embodiments, when no generated custom media content is stored in the display device, for example, after the display device leaves the factory, the user has not yet generated custom media content through the display device, the list of generated media content displayed in the first display area may be empty. At this time, a prompt message that allows custom generated media content may be given on the homepage of the target application at the same time, for example: you have not generated any media content, do you want to enter text information to generate custom media content, etc. It is understandable that the prompt message may also have other settings.

[0139] An unfinished media content generation task is a media content generation task for which a media content generation request is sent to a server based on received text content, but the generated media content has not yet been received from the server.

[0140] In some embodiments, the controller is configured to generate a media content generation task upon receiving information content input by the user, send a media content generation request to the server, and record a task status identifier of the media content generation task. The specific type of the task status identifier is not limited, as long as it can reflect the different states of the media content generation task, for example, it can be simply unfinished, completed, or requesting, generating, completed, etc., or it can be the generation progress of the media content generation request obtained by communicating with the server through the communication device, such as 50%, 70%, etc., but not limited thereto.

[0141] Among them, the controller sends a media content generation task query request to the server through the communication device. For example, the media content generation task query request can be sent to the server only once. After the media content generation task is completed, that is, after the media content is generated, the server returns the information that the media content generation is completed to the display device.

[0142] In some embodiments, the controller may also send a media content generation task query request to the server via a communication device in a polling manner, that is, send a media content generation task query request to the server via the communication device at regular intervals to be able to timely learn the execution progress of the media content generation task.

[0143] The duration of the interval is not limited. In some embodiments, the interval duration may be fixed, or may be determined based on the estimated completion duration of the media content generation task.

[0144] In some embodiments, the controller 250 is also configured to, upon receiving an operation to select a target application, obtain an interval duration determined based on the estimated completion duration of the unfinished media content generation task if there is an unfinished media content generation task, and after the interval duration expires, send a media content generation task query request to the server via the communication device 260.

[0145] There is no limitation on the method of determining the interval duration based on the estimated completion duration of the unfinished media content generation tasks. Some embodiments can determine the interval duration by the average value, weighted sum, maximum value, minimum value or other calculation method of the estimated completion duration of each unfinished media content generation task.

[0146] In some embodiments of the present application, the controller 250 is further configured to determine the estimated completion time with the smallest value among the estimated completion times of the unfinished media content generation tasks as the interval time.

[0147] By using the smallest estimated completion time among the estimated completion times of the unfinished media content generation tasks, the progress of the unfinished media content generation tasks can be tracked in a timely manner, and whether the earliest possible completed media content has been generated can be known in a timely manner, which helps to improve the efficiency of media content status update.

[0148] There is no limitation on the method of updating the generated media content list. In some embodiments, the information of the newly generated media content can be added at the end of the generated media content list, or at the beginning of the generated media content list, so as to facilitate the user to view the media content of the newly generated media content in a timely manner.

[0149] Among them, the specific form of the media content of the media content is not limited. In the embodiment of the present application, the media content can be a media content video content, and each frame of the video content includes a generated video picture and corresponding media content text content.

[0150] The display device based on this embodiment can receive an operation of selecting a target application through the device homepage after displaying the device homepage, so as to start the target application and display the target application homepage, and the target application homepage will display a list of generated media content, so that the list of media content generated by the display device can be viewed intuitively and conveniently. When receiving an operation of selecting a target application through the device homepage, if there is an unfinished media content generation task, a media content generation task query request is also sent to the server to query and obtain the progress of the unfinished media content generation task, and when receiving information on the completion of media content generation, the generated media content is downloaded from the server through the communication device, so that the generation of media content that was not generated when the target application was started last time can be realized imperceptibly by starting the target application, which can help improve the efficiency of media content generation, realize real-time update of the generated media content list, and improve user experience.

[0151] In some embodiments, the controller 250 is further configured to display a media content screen of the media content corresponding to the focus on the background of the target application homepage when the focus of the display device is located on one of the media contents in the generated media content list.

[0152] By displaying the media content screen of the media content corresponding to the focus on the background of the target application homepage, the media content of the media content corresponding to the focus can be previewed more intuitively, and a reference can be provided for the user whether to view the media content of the media content corresponding to the focus.

[0153] based on Figure 5 The display device shown, in some embodiments:

[0159] In some embodiments, the display device further includes a sound collector;

[0160] The controller 250 is further configured to obtain voice input information through a sound collector, and determine whether a media content adding instruction is received based on the voice input information.

[0161] When the display device is equipped with a sound collector, voice input information can be obtained through the sound collector, and based on the voice input information, it can be determined that an instruction to add media content has been received. For example, when similar information with voice indicating the addition of new media content, such as "add new media content", "create new media content", "I want to draw a picture book", etc., is received, it can be considered that an instruction to add media content has been received.

[0162] Based on the display device of this embodiment, a media content adding entry may be provided on the device homepage of the display device. When a media content adding instruction is received through the device homepage, a target application may be started and the target application homepage may be displayed. The target application homepage may also display a list of generated media content, so that the list of media content generated by the display device may be viewed intuitively and conveniently. When an operation of selecting a target application is received through the device homepage, in the case where there is an unfinished media content generation task, a media content generation task query request is also sent to a server to query and obtain the progress of the unfinished media content generation task. When information on the completion of media content generation is received, the generated media content is downloaded from the server through a communication device. Thus, by starting the target application, the generation of media content that was not generated when the target application was started last time can be realized imperceptibly, which can help improve the efficiency of media content generation, realize real-time updating of the generated media content list, and improve user experience.

[0163] Among them, other implementation methods of the display device of this embodiment may be the same as those of the display device in the above-mentioned embodiment, and will not be described in detail here.

[0169] The media content generation input interface is an interface that can trigger the generation of custom media content. In some embodiments, the media content generation input interface may have an input box for inputting information content. For example, text content may be input through the keys of a control device, information content may be input through a touch device of a display, or text content may be obtained by recognizing voice information collected by a sound collector. In the case of obtaining text content by recognizing voice information collected by a sound collector, a prompt control for sound collection may be set at a preset position of the text content input box, such as Figure 7 The 701 is shown.

[0170] The information input component is used to receive input information content.

[0171] The specific form of the information input component is not limited. In some embodiments, the information input component may include a sound collection component or a voice input component, and in some embodiments, the information input component may include an information input box. In some optional embodiments, the information input component may include both a sound collection component and an information input box, so that the text content of the voice recognition information collected and recognized by the sound collector based on the sound collection component can be displayed in the information input box for user verification, and high interactive performance can be achieved.

[0172] The form of the information content is not limited, such as text, voice or image. In some embodiments, for the information content received in the form of text, voice, etc., the received text content or the text content obtained by voice recognition of the voice can be displayed in the information input box, such as Figure 8 As shown, Figure 8 In the figure, the received text content or the text content obtained by voice recognition of the voice is "The protagonist is a cute little rabbit, and it lives in a beautiful forest." In the case where the text content is input through the sound collector, the prompt control of the sound collection can be adjusted to the input mode, such as Figure 8 As shown in 801.

[0173] Accordingly, in some embodiments, the controller 250 is further configured to send a media content generation instruction to the server through the communication device 260 based on the information content received by the information input component, the media content generation instruction including the information content, and the media content generation instruction is used to instruct the server to generate media content based on the information content.

[0175] In some embodiments, the media content generation input interface may further include media content generation prompt information, which is used to prompt prompt information related to custom generated media content. For example, the target application is a picture book application. Figure 7 As shown in the media content generation input interface of "Create a picture book with one sentence" and "Use one sentence to start a fantasy picture book journey and unleash unlimited creative imagination", it can be understood that in other embodiments, the media content generation prompt information can also be other text content, not limited to this.

[0176] In some embodiments, the media content generation input interface may further include text content example information, through which the user may provide a reference for inputting information content. For example, the target application is a picture book application. Figure 7 The media content generation input interface shows "Sugar Heart Candy Kingdom", "How to Solve the Problem of Children's Crying", and "How to Guide Children to Develop Stable Emotions". It can be understood that in other embodiments, the text content example information may also be other content, not limited to this.

[0177] In some embodiments, after receiving information content input by the user through the media content generation input interface, any one of the character selection page, the tone selection page and the painting style selection page may be further displayed.

[0178] The controller 250 is also configured to display at least one of a character selection page, a timbre selection page and a painting style selection page after receiving information content input by a user through a media content generation input interface, and generate and send a media content generation instruction to a server based on the character identifier obtained on the character selection page, the timbre identifier obtained on the timbre selection page, the painting style identifier obtained on the painting style selection page, and the information content received by the information input component.

[0179] The role selection page is a page for displaying selectable media content roles. The role selection page may display a plurality of selectable media content roles. In some embodiments, the role selection page may include: Fig. 9 As shown, Fig. 9In the figure, some media content roles that can be selected are shown.

There is no restriction on the way of analyzing the input image to obtain the image style. Thus, an entry for users to customize the design of media content styles can be provided, further enhancing the interactive performance and user experience of the target application.

[0185] Among them, after receiving the information content input by the user through the media content generation input interface, the character selection page, the tone selection page and the painting style selection page are displayed in sequence as an example. In the media content generation input interface, the character selection page and the tone selection page, a control for entering the next display page can also be displayed. Taking the target application as a picture book application as an example, for example Figure 8 , 9 , and the "next page" control shown in 10, a control for returning to the next display page can also be displayed on the character selection page, the tone selection page, and the painting style selection page, such as Fig. 9 , 10 , the "Previous Page" control shown in Figure 11, which makes it easy to adjust the information content entered by the user, the selected role, the timbre, etc.

[0186] In some embodiments, after receiving the information content input by the user through the media content generation input interface, the character selection page, the tone selection page and the painting style selection page are displayed in sequence as an example. Page setting progress information can also be set above each page, such as Figure 8 802 Fig. 9 901 in Fig.10 1001 of Fig.11 1101 in the figure, and when switching between different pages, the node marks corresponding to different pages in the page setting progress information can be adjusted, for example, the node marks that have been set to completed are adjusted to √, the nodes marked on the page being set are enlarged and displayed, etc., but not limited to this.

[0187] Among them, when the last setting page is displayed, for example Fig.11 The style selection page shown in FIG. 1 may be provided with controls for indicating the generation of media content, such as Fig.11 The “Generate Now Control” shown in the figure can issue a media content task generation instruction by clicking the Generate Now Control.

[0188] In some embodiments, the number of times of custom generation through the display device may be limited, and displayed on the last setting page, adjacent to the control for receiving the media content task generation instruction, for example Fig.11As shown in the “Can be generated twice more today”, the resources for generating custom media content can be managed and controlled.

[0189] Based on the display device of this embodiment, a media content adding entry may be provided on the device homepage of the display device. When a media content adding instruction is received through the device homepage, the target application may be started, and the display may be switched to a media content generation input interface to directly and conveniently realize the generation of media content. Moreover, when an operation of selecting a target application is received through the device homepage, in the case where there is an unfinished media content generation task, a media content generation task query request is also sent to a server to query and obtain the progress of the unfinished media content generation task, and when information on the completion of the media content generation is received, the generated media content is downloaded from the server through a communication device, so that the generation of media content that was not generated when the target application was started last time can be realized imperceptibly by starting the target application, which can help improve the efficiency of media content generation and improve user experience.

[0190] Among them, other implementation methods of the display device of this embodiment may be the same as those of the display device in the above-mentioned embodiment, and will not be described in detail here.

[0191] In some embodiments, a display device is also provided, referring to Fig.12 As shown, it includes: a display 260, a sound collector 2301, a communication device 220 and a controller 250, and the display 260, the sound collector 2301, the communication device 220 and the controller 250 are communicatively connected.

[0193] based on Fig.12 The display device shown, in some embodiments:

[0194] a display 260 configured to display a graphical user interface;

[0195] The sound collector 2301 is configured to collect sound information;

[0196] The communication device 220 is configured to establish a communication connection with the server;

[0197] The controller 250 is configured to start the target application and display the target application home page when receiving the media content generation instruction through the sound collector 2301, wherein the first display area of ​​the target application home page displays the generated media content list, and the focus of the display device is located on a media content in the generated media content list;

[0198] The controller 250 is also configured to, upon receiving a media content generation instruction, send a media content generation task query request to the server via the communication device 260 if there is an unfinished media content generation task, and upon receiving information that the media content generation is completed, download the generated media content from the server via the communication device 260 and update the generated media content list.

[0199] There is no limitation on the way of receiving media content generation instructions through the sound collector 2301. For example, voice input information is obtained through the sound collector, and it is determined based on the voice input information that the media content generation instruction has been received. For example, when similar information with voice indicating the generation of new media content, such as "generate new media content", "create new media content", "establish new media content", "generate my media content", etc., is received, it can be considered that the media content generation instruction has been received.

[0200] Among them, the controller 250 can receive the media content generation instruction through the sound collector 2301 when the display displays any possible interface, for example, when the display displays the device home page, when the display displays the interface of other applications other than the target application, or when the display displays the interface of the target application. It is understandable that when the media content generation instruction is received when the display displays the interface of the target application, the target application is already in the startup state at this time, and the target application home page can be directly displayed.

[0201] Based on the display device of this embodiment, it can start the target application through voice triggering, display the target application homepage, and the target application homepage will display the list of generated media content, so that the list of media content generated by the display device can be viewed intuitively and conveniently. When receiving the operation of selecting the target application through the device homepage, if there is an unfinished media content generation task, it also sends a media content generation task query request to the server to query and obtain the progress of the unfinished media content generation task, and when receiving the information that the media content generation is completed, it downloads the generated media content from the server through the communication device, so that by starting the target application, the generation of media content that was not generated when the target application was started last time can be realized imperceptibly, which can help improve the efficiency of media content generation, realize real-time update of the generated media content list, and improve user experience.

[0202] Among them, other implementation methods of the display device may be the same as those of the display device in the above embodiment, and will not be repeated here.

[0203] based on Fig.12 The display device shown, in some embodiments:

[0207] The controller 250 is configured to switch to displaying a media content generation input interface when receiving a media content generation instruction through the sound collector 2301, and the media content generation input interface includes an information input component;

[0208] The controller 250 is also configured to, upon receiving a media content generation instruction, send a media content generation task query request to the server via the communication device 260 if there is an unfinished media content generation task, and upon receiving information that the media content generation is completed, download the generated media content from the server via the communication device 260.

[0209] The display device based on this embodiment can start the generation of custom media content through voice triggering. No matter what interface is displayed, when the sound collector 2301 receives the media content generation instruction, it can directly switch to displaying the media content generation input interface to directly and conveniently realize the generation of media content. Moreover, when receiving the operation of selecting the target application through the device homepage, if there is an unfinished media content generation task, it also sends a media content generation task query request to the server to query and obtain the progress of the unfinished media content generation task, and when receiving the information that the media content generation is completed, it downloads the generated media content from the server through the communication device, so that by starting the target application, the generation of media content that was not generated when the target application was started last time can be realized imperceptibly, which can help to improve the efficiency of media content generation and improve user experience.

[0210] Among them, other implementation methods of the display device may be the same as those of the display device in the above embodiment, and will not be repeated here.

[0211] Based on the display device of each embodiment described above, in some embodiments, the controller 250 is further configured to cyclically display the media content screen of the previous preset time length of the media content corresponding to the focus on the background of the target application homepage.

[0212] The specific value of the preset duration is not limited, and can generally be determined based on the processing capability of the display device and the duration that can concisely represent the media content. For example, the preset duration in some embodiments can be 3s (seconds)-10s, and in some specific examples can be 5s. It is understandable that in other embodiments, the preset duration can also be set in other ways.

[0213] In some embodiments, the controller 250 is further configured to display the media content title and media content introduction of the media content in the background of the target application homepage.

[0214] The media content title may be generated in any manner, and may be a title customized by a user, or may be a media content title generated by a first language model based on information content input by a user, but is not limited thereto.

[0215] The media content introduction is an overview of the media content, which can be a summary of the media content generated by the second language model based on the information content input by the user, or it can be a media content introduction obtained by summarizing the content of the generated media content based on the content of the generated media content after the server generates the media content based on the information content input by the user. There is no limit to the way of summarizing the content of the media content, for example, a media content introduction obtained by summarizing the content of the media content through the third language model.

[0229] Based on this embodiment, when a certain media content is selected, the media content of the media content can be displayed, so that the media content of the media content can be viewed, which helps to improve the use experience of the target application.

[0230] The selection instruction is an instruction for indicating the selection of opening a media content corresponding to a media content. The selection instruction can be obtained in various possible ways.

[0231] In some embodiments, the controller 250 is further configured to determine that a selection instruction to select one of the media contents is received when a confirmation operation of the control device is received while the focus of the display device remains unchanged.

[0232] The received confirmation operation, taking the control device controlling the display device as an example, may be an operation indicating confirmation after receiving “confirmation”, “OK” or a similar button of the control device.

[0233] Based on this embodiment, when a confirmation operation of the control device is received while the focus of the display device remains unchanged, it can be considered that a selection instruction to select one of the media contents has been received, and the media content corresponding to the focus of the display device is determined to be the media content selected by the user, and then the media content corresponding to the focus of the display device is opened and displayed.

[0234] In some embodiments, the display device further includes a sound collector;

[0235] The controller 250 is further configured to obtain voice input information through a sound collector, and determine, based on the voice input information, that a selection instruction for selecting a certain media content has been received.

[0236] In the case where the display device has a sound collector, voice input information can be obtained through the sound collector, and based on the voice input information, it is determined that a selection instruction for selecting a certain media content has been received. Figure 6 Taking the target application homepage shown as an example, when similar voice input information such as "open the second media content", "open the second one", "watch the second one" is received, it is considered that a selection instruction for the media content corresponding to the media content 6011 is received.

[0237] Based on this embodiment, it can be determined whether a selection instruction for selecting media content is received through the voice input information received by the sound collector. The selection method is simple and convenient. Even users who are not flexible in operating the control device, such as users with limited experience or the elderly, can easily open the selected media content for viewing.

[0238] In some embodiments, the controller 250 is further configured to display a playback progress bar on the interface for playing the media content within a first preset duration of opening the interface for playing the media content, and not display the playback progress bar after the first preset duration. The specific duration range of the first preset duration is not limited, for example, the first preset duration in some embodiments can be set to 3s.

[0239] In some embodiments, the controller 250 is further configured to display a playback progress bar in response to an operation on the media content playback area when displaying the interface for playing the media content. Fig.15 shown. Fig.15 As shown, in the playback progress bar, the length of the progress bar corresponding to the media content that has been played and the length of the progress bar corresponding to the media content that has not yet been played can be represented by different progress bars, and the playback time and the overall playback time of the media content can be displayed in adjacent positions of the progress bar to prompt the playback time.

[0240] Among them, the operation method of the media content playback area is not limited. Taking the control of the display device through the control device as an example, when the interface of playing media content is displayed, if the "OK" key, "Confirm key" and other key instructions of the control device are received, it is considered that the operation of the media content playback area has been received, and the playback progress bar is displayed.

[0241] After the playback progress bar is displayed, if no operation on the interface for playing the media content is received within the second preset time, the playback progress bar is not displayed. The second preset time may be the same as or different from the first preset time.

[0242] In some embodiments, the controller 250 is further configured to adjust the playback progress of the media content in response to a playback progress adjustment operation when displaying an interface for playing the media content.

[0243] The manner of receiving the playback progress adjustment operation is not limited. For example, the playback progress adjustment operation can be received via the playback progress bar. Accordingly, in some embodiments, the controller 250 is further configured to adjust the playback progress of the media content in response to a drag operation on the playback progress bar when the playback progress bar is displayed on the interface for displaying the playback media content.

[0244] There is no limit to the dragging operation of the playback progress bar. Taking the control of the display device through the control device as an example, when the playback progress bar is displayed, if an instruction of the left button of the operation control device is received, it can be considered that a playback progress adjustment operation of the first step length of playback backward is received. If an instruction of the right button of the operation control device is received, it can be considered that a playback progress adjustment operation of the second step length of playback forward is received. The first step length and the second step length can be the same or different.

[0245] In some embodiments, the playback progress adjustment operation can be received through the voice input information collected by the sound collector. For example, if the voice input information collected by the sound collector is "rewind ** seconds", it is considered that the playback progress adjustment operation of rewinding ** seconds is received, and if the voice input information collected by the sound collector is "forward ** seconds", it is considered that the playback progress adjustment operation of forward ** seconds is received.

[0246] In some embodiments, the controller 250 is further configured to control the pause / resume of the playback in response to an operation on the playback area of ​​the media content when playing the interface of the media content.

[0247] In some embodiments, the controller 250 is further configured to switch to displaying the target application home page in response to exiting the playback operation when displaying the interface for playing media content.

[0248] There is no limitation on the way to obtain the exit playback operation, for example, the operation of double-clicking the "return" key of the control device may be received, or the information of "return to the application homepage" received by the sound collection device may be received, but it is not limited thereto.

[0249] Based on the above-described examples, during the process of playing the media content, the progress of playing the media content and the mechanism for exiting the media content playing can also be controlled, which helps to further improve the user experience.

[0250] In the process of playing the media content, the page turning of the media content can also be controlled. The page turning control method is not limited, for example, the page turning control can be performed by voice input information collected by the sound collector, or by recognizing the image collected by the image collector and controlling the page turning based on the image recognition result.

[0251] Taking page turning control based on image recognition results as an example, during the playback of media content, the image collector can be started to obtain images collected by the image collector, and gesture recognition can be performed on the collected images to determine the motion trajectory of the recognized gesture. If the recognized motion trajectory matches the preset trajectory of the next page (for example, the similarity is greater than the preset similarity threshold), it is determined that the switch to the next page instruction is received and the page is turned to the next page. If the recognized motion trajectory matches the preset trajectory of the previous page (for example, the similarity is greater than the preset similarity threshold), it is determined that the switch to the previous page instruction is received and the page is turned to the previous page.

[0252] In some embodiments, the display device further includes a memory;

[0253] A memory configured to store a task status identifier of a media content generation task;

[0254] The controller 250 is also configured to send a media content generation task query request to the server through the communication device 260 when there is a media content generation task whose task status is identified as incomplete, and the media content generation task query request includes the media content generation task identifier of the media content generation task whose task status is identified as incomplete.

[0255] The task status identifier is an identifier used to mark the execution status of the media content generation task. The specific method of the task status identifier is not limited. In combination with the above example, if the task status identifier of the media content generation task is unfinished, requesting, not generated, or not 100%, it means that the media content generation task is not completed, and a media content generation task query request is sent to the server through the communication device.

[0256] The media content generation task identifier is an identifier used to uniquely identify a media content generation task, and can be generated when a user triggers the creation of a media content generation task. There is no limit to the way to generate the media content generation task identifier, for example, it can be generated based on the time when the creation of the media content generation task is triggered, the text content received when the creation of the media content is triggered, etc., but it is not limited to this, as long as it can uniquely identify a media content generation task.

[0257] By sending a media content generation task query request to the server through the communication device 260, the status of the server executing the media content generation task can be queried from the server, and after knowing that the server has generated the media content, the corresponding media content can be downloaded in time.

[0258] Based on this embodiment, after starting the target application, if there is an unfinished media content generation task, a media content generation task query request is also sent to the server. If there is an unfinished media content generation task, by sending the media content generation task query request including the media content generation task identifier to the server, the status of the unfinished media content generation task when the target application was last closed can be followed up, and the generation of media content that was not generated when the target application was last started can be realized imperceptibly, which can help improve the efficiency of media content generation, realize real-time updating of the generated media content list, and improve user experience.

[0259] In some embodiments, the memory is further configured to store the generated media content;

[0260] The controller 250 is also configured to receive information on the completion of media content generation sent by the server, the information including a media content generation task identifier and a media content address, download the generated media content from the media content address through the communication device 260, and update the task status identifier of the media content generation task corresponding to the media content generation task identifier based on the media content generation task identifier.

[0261] Among them, the information on the completion of media content generation received from the server can be the information returned by the server after completing the media content generation task corresponding to the media content generation task identifier and after receiving the media content generation task query request sent by the display device, or it can be the information actively returned to the display device after the server completes the media content generation task corresponding to the media content generation task identifier, but it is not limited to this, as long as it can be known that the server has completed the media content generation task corresponding to the media content generation task identifier.

[0262] After the server generates the media content corresponding to the media content generation task identifier, it can generate a storage address for the media content, obtain the media content address, and store the media content in a storage location corresponding to the storage address. After the display device obtains the media content address, it can download the generated media content from the media content address.

[0263] The timing of updating the task status identifier of the media content generation task corresponding to the media content generation task identifier based on the media content generation task identifier is not limited. The task status identifier of the media content generation task corresponding to the media content generation task identifier can be updated after receiving the information that the media content generation is completed sent by the server, for example, the task status identifier is updated to completed. In some embodiments, the task status identifier of the media content generation task corresponding to the media content generation task identifier can be updated after the media content of the generated media content is downloaded from the media content address and the downloaded media content is stored in the memory of the display device, so that when the media content corresponding to the media content generation task is already stored, the task status identifier is updated, which helps to improve the accuracy of the task status identifier update.

[0264] Based on this embodiment, after obtaining the media content generation task identifier and the media content address returned by the server, the task status identifier of the media content generation task can be updated based on the media content generation task identifier, and the media content of the generated media content can be downloaded based on the media content address, thereby achieving dual update of the task status identifier and the stored media content.

[0265] In some embodiments, the controller 250 is further configured to display a prompt message indicating that the media content has been generated on a display interface of the display after the generated media content is downloaded from the media content address via the communication device 260 .

[0266] The prompt information that the media content has been generated and displayed on the display interface is used to prompt that a new media content has been generated.

[0267] There is no limitation on the manner of displaying the prompt information that the media content has been generated on the display interface of the display 260. In some embodiments, the prompt information can be provided by a pop-up window. The prompt content of the prompt information is not limited, for example, "***'s media content has been generated", etc., but is not limited to this.

[0268] In some embodiments, the controller 250 is further configured to switch to an interface for displaying the media content generated by the download if a viewing instruction for the prompt information is received.

[0269] There is no limitation on the method of receiving the viewing instruction for the prompt information.

[0270] In some embodiments, taking the example of providing prompt information by means of a pop-up window, if an operation instruction of clicking the pop-up window is received, it is considered that a viewing instruction for the prompt information is received.

[0271] In some embodiments, when the display device is equipped with a sound collector, voice input information can be obtained through the sound collector, and based on the voice input information, it can be determined whether a viewing instruction has been received. For example, if voice input information such as "view new media content" or "view newly generated media content" is received, it is considered that a viewing instruction for the prompt information has been received.

[0272] The content of the interface that is switched to display the media content generated by the download is not limited. In some embodiments, the interface that is switched to display the media content generated by the download may be an interface containing introduction information of the newly generated media content, such as the text content contained when the generation of the media content is triggered, etc. The interface may contain controls such as "OK" and "View" for indicating the opening of the media content. When the operation of clicking the control is received, it is switched to the interface for playing the media content generated by the download. In some embodiments, the interface that is switched to display the media content generated by the download may also be directly an interface for playing the media content generated by the download.

[0273] Based on this embodiment, after the generated media content is downloaded from the media content address through the communication device, a prompt message that the media content has been generated is displayed on the display interface of the display, so that the user can be prompted that the new media content has been generated, which can help the user to view the content of the newly generated media content in time. By receiving a viewing instruction for the prompt message, it is possible to conveniently switch to the relevant interface of the newly generated media content when the prompt message is displayed, which helps to improve the efficiency of viewing the newly generated media content and helps to improve the user experience.

[0276] The controller 250 is further configured to output audio prompt information indicating that the media content has been generated through the audio output device 270 after the generated media content is downloaded from the media content address through the communication device 260 .

[0277] The audio prompt information indicating that the media content has been generated outputted by the audio output device 270 is used to prompt through voice that a new media content has been generated.

[0278] The specific content of the audio prompt information is not limited. In some embodiments, a preset audio is stored in the memory of the display device, and the preset audio is played to prompt that a new media content has been generated. The preset audio can be preset by the display device or custom generated based on the user's settings.

[0279] In some embodiments, a preset audio template is stored in the memory of the display device, and the audio prompt information is generated in combination with the text content contained when the new media content is triggered to be generated and the preset audio template. For example, if the text content contained when the new media content is triggered to be generated is "******", an audio prompt information of "media content about ****** has been generated" can be generated, but it is not limited to this.

[0280] When the audio prompt information is output through the audio output device, if the audio output device is outputting audio, in some embodiments, the volume of the audio being output by the audio output device can be turned down, and the audio prompt information can be superimposed on the audio being output and output, in some embodiments, the output of the audio being output can be paused, and the audio prompt information can be output, and in other embodiments, the audio prompt information can also be output in other ways. In the case of pausing the output of the audio being output and outputting the audio prompt information, if the audio being output is the audio of the media content being played, the playing of the media content can be paused, or the playing of the media content can be continued.

[0281] In some embodiments, when the display device has a sound collector, the controller 250 is further configured to obtain voice input information through the sound collector 2301 after playing the audio prompt information, and determine whether a viewing instruction is received based on the voice input information, and if a viewing instruction is received, switch to an interface for displaying the media content of the downloaded generated media content. For example, if a similar voice input information such as "view new media content" or "see newly generated media content" is received, it is considered that a viewing instruction for the prompt information has been received.

[0282] The content of the interface for displaying the downloaded generated media content is the same as that in the above embodiment, and will not be described in detail here.

[0283] Based on this embodiment, after the generated media content is downloaded from the media content address through the communication device, the information that the media content has been generated can be prompted by voice, so that even for users who have difficulty in character recognition, such as children or users with poor eyesight, they can know that new media content has been generated through the voice prompt information, and can view the media content of the newly generated media content in a timely manner on this basis. By receiving the viewing instruction for the prompt information, it is convenient to switch to the relevant interface of the newly generated media content, which helps to improve the efficiency of viewing the newly generated media content and helps to improve the user experience.

[0284] In some embodiments, the controller 250 is further configured to display a quantity indicator of the generated media content on the homepage of the target application, and to update the quantity indicator after the generated media content is downloaded from the server via the communication device 260 .

[0285] The identifier of the number of generated media contents may be an identifier used to indicate the number of media contents stored in the memory of the display device, or an identifier used to indicate the number of media contents custom-generated by the display device based on received text contents.

[0286] The quantity identifier may be stored in a memory of the display device, and the display position and display method of the quantity identifier on the homepage of the target application are not limited. In some embodiments, the quantity identifier of the generated media content may be displayed in a corner mark.

[0287] In some embodiments, the controller 250 is further configured to display the number of generated media content in the corner mark of the banner image of the target application in the device homepage carousel. Therefore, when the device homepage is opened, the number of generated media content can be known through the corner mark of the banner image of the target application in the device homepage, which is intuitive and convenient.

[0288] In some embodiments, the memory is further configured to record a viewing identification of the media content;

[0289] The controller 250 is further configured to display a number indicator of the media content marked as unviewed in a corner mark of the banner image of the target application in the carousel on the device home page.

[0290] The viewing flag is used to identify whether the media content has been viewed. The implementation of the viewing flag is not limited. In some embodiments, if the viewing flag is a first value, such as "yes" or "1", it means that the media content corresponding to the media content flag has been viewed. If the viewing flag is a second value, such as "no" or "0", it means that the media content corresponding to the media content flag has not been viewed, and this startup is the first startup.

[0291] The controller 250 is further configured to, upon receiving a selection instruction for selecting one of the media contents, determine a viewing identifier corresponding to the media content identifier corresponding to the selection instruction, and update the viewing identifier corresponding to the media content identifier corresponding to the selection instruction to viewed if the viewing identifier is not viewed.

[0293] The specific value of the preset playback time is not limited, and it may be pre-set in the display device, or may be a preset playback time set by a user.

[0294] Based on this embodiment, when the playback duration of the media content identified by the media content identifier corresponding to the selection instruction is greater than or equal to the preset playback duration, it indicates that the viewing of the media content has reached the preset playback duration. Only then is the viewing identifier corresponding to the media content identifier corresponding to the selection instruction updated to viewed, which helps promote effective viewing of the media content.

[0295] During the application process of the target application, when previously ungenerated media content is downloaded from the server, the user may not have viewed the newly generated media content. By recording the viewing identifier of the media content and displaying the number identifier of the unviewed media content in the corner mark of the banner image of the target application that is rotated on the device homepage, the user can be informed in time that there is newly generated and unviewed media content when opening the device homepage of the display device, thereby facilitating the user to view the newly generated media content.

[0296] In some embodiments, the controller 250 is further configured to send a media content generation task cancellation instruction to the server through a communication device when receiving the media content generation task cancellation instruction, the media content generation task cancellation instruction includes a media content generation task identifier, and the media content generation task cancellation instruction is used to instruct the server to stop the media content generation task corresponding to the media content generation task identifier.

[0297] Among them, the method of obtaining the media content generation task cancellation instruction is not limited. In some embodiments, the task generation progress interface of the media content generation task can be displayed, and controls such as "Cancel" are displayed in the task generation progress interface.

[0314] The basic service of the display device may be, for example, TvBaseService. When there is a new media content generation task or the media content generation task is completed, it actively updates the corresponding attribute identifier, such as updating the persist attribute identifier. In some examples, when the attribute identifier is 0, it means there is no task, and when the attribute identifier is 0, it means there is a task. When receiving the startup broadcast of the display device, the entire attribute identifier is judged. When the attribute value is 1, the background service is called to query and download the media content task.

[0315] The UI interface module of the target application can realize the display and control of the relevant interfaces of the target application (such as the target application guide page, the target application home page, the relevant drawing page, and the playback page).

[0316] The media content browsing module can realize media content browsing. The media content video playback module can realize the playback of the selected media content and the control during the playback process. The parental setting module can realize the relevant settings of the target application, such as the time range in which the target application can be used, the amount of media content that can be generated per day, etc., but not limited to this. The download module can be used to download media content from the server based on the media content address. The media content generation service management module can detect the status of the media content generation task and send a query request to the server by polling. The database management module can be used to manage the status of the media content stored in the memory. The drawing paper parameter management module can be used to set and manage the image quality parameters when playing media content.

[0317] In the control process of the above modules, SDK (Software Development Kit) can be used. Some possible SDK toolkits may include but are not limited to SDKs related to HiSDK, unified network framework, unified broadcast control, middleware, voice recognition, network management and download components.

[0318] Among them, the middleware interface in some examples can implement preview delivery and manual exit of different modes of the target application through Flow, and can monitor the status of the target application. When the target application exits abnormally or the scene switches quickly, it can automatically exit the preview image mode. The voice recognition interface can perform voice recognition and convert the input voice into input text content.

[0319] In some optional examples, the target application and the basic service of the display device can call the flow interface PictureManager.setPictureModePreview(value) to issue a preview image mode, and the target application and the notification service can call the notification center AIDL interface addNotification to send prompt information, such as prompting that media content generation is complete.

[0320] Taking entering the target application after entering the homepage, and the target application is a picture book application as an example, in the processing process of the display device in some embodiments, the timing diagram of the interaction process of the relevant modules of the display device is as follows: Fig.17 The flowchart of the relevant processing process is shown in Fig.17 shown.

[0321] Combination Fig.17 and Fig.18 As shown, after the user clicks the picture book application icon, the picture book application is started and the parameters of the picture book application are initialized.

[0322] By querying the first start flag stored in the memory, it is determined whether the target application is started for the first time. In some embodiments, the first start flag can be stored in SharePreference. For example, if there is data in SharePreference, it is considered not the first start, and if there is no data, it can be considered the first start.

[0323] If the picture book application is started for the first time, the layout of the picture book application boot page is loaded, the controls of the picture book application boot page are initialized, the picture book application boot page is displayed, and the first start flag stored in the memory is modified, such as writing data in SharedPreference, and when the user clicks to start the experience (for example Fig.13(C) and then enter the picture book application homepage. Wherein, in the case where a right to know prompt page is provided, after the user clicks to start the experience, the right to know prompt page is displayed, and after receiving the consent operation, the picture book application homepage is entered. In other embodiments, after the right to know prompt page is displayed and the consent operation is received, the layout of the picture book application guide page is loaded, the controls of the picture book application guide page are initialized, the picture book application guide page is displayed, the first startup flag stored in the memory is modified, and the picture book application homepage is entered after the user clicks to start the experience.

[0324] If this is not the first time you launch the picture book app, you can directly enter the homepage of the picture book app.

[0325] Initialize the home page of the picture book application, and query the changes of local picture book data in the database by accessing the database management service, such as querying all locally generated picture books. After obtaining the data returned by the database management service, parse and load the picture book list data that displays the home page of the picture book application, and read the background data (image or video based on multiple frames of images) of the first picture book in the picture book list as the background of the picture book application home page.

[0326] By querying the completion status of the picture book generation tasks in the database, all unfinished picture book generation tasks are filtered out, and the number of corner marks is updated based on the number of unfinished picture book generation tasks.

[0327] The media content generation task management module monitors whether the display device is connected to the Internet. If not, it continues to monitor network changes. If the network is continuously disconnected, for example, the network has been disconnected for a certain period of time, it stops sending polling query requests, prompts the user and cancels the polling, and continues to monitor network changes.

[0328] If the display device is in a networked state and the storage space of the memory of the display device is greater than a preset value, the task of sending the polling query request is started.

[0329] When sending a polling query request, if there are multiple unfinished picture book generation tasks, a picture book generation task can be selected according to certain rules, and a query request can be sent based on the estimated completion time of the picture book generation task. In some embodiments, the picture book generation tasks can be arranged in ascending order according to the estimated completion time, and the picture book generation task with the shortest estimated completion time is selected, and the query request is initiated after the shortest estimated completion time.

[0330] Taking the polling query request initiated by the picture book generation task with the shortest estimated completion time as an example, the scheduled task can be started according to the estimated completion time of the picture book generation task, and the scheduled time of the scheduled task is the estimated completion time of the picture book generation task, and when the scheduled task ends, a query request is sent to the server. In this embodiment, only one scheduled task can be set, and when one scheduled task ends, the next scheduled task is started.

[0331] Among them, when the picture book generation task has been completed, you can find the next picture book generation task for scheduled query and set the scheduled task for the next picture book generation task.

[0332] If the picture book generation task is not completed, for example, after sending a query request, the server returns the information that it is not completed, then the estimated completion time of the picture book generation task in the database is updated according to the estimated time returned by this query, and each picture book generation task is re-arranged in ascending order according to the estimated completion time, and the picture book generation task with the shortest estimated completion time is selected, and a query request for the picture book generation task is initiated until the status of all picture book generation tasks is completed.

[0333] Among them, after sending a query request to the server, if the returned query result is that the download has expired or other failure status, the status of the picture book generation task can be updated to a canceled status, and the picture book generation task will not be queried subsequently.

[0334] During the process of sending the query request, if the network is not good, the access timeout occurs, or the network request returns abnormally, the polling will be canceled and the user will be prompted that the network is abnormal.

[0335] Based on the received query request, the server can return the execution status of the picture book generation task. If the picture book generation task has been completed, the returned information can also include the storage address of the generated picture book.

[0336] After receiving the information returned by the server, the generation task management module monitors that if the returned information contains information of successful generation, it will parse the storage address of the picture book, download the picture book file from the storage address through the download module and save it. After saving the picture book file, the generation task management module updates the completion status of the picture book generation task, and updates the completion status of the picture book generation task recorded in the database and the save path of the generated picture book, and sends notification information through the relevant modules of the notification center.

[0337] The module related to the picture book application homepage monitors the changes of data in the database and updates the data of related pages.

[0338] For example, the number of unfinished picture book generation tasks is monitored. If the number does not change, the monitoring continues. If the number changes, when the number of unfinished picture book generation tasks is indicated by a badge, the badge number is updated and refreshed.

[0339] Monitor the changes in the number of completed picture book generation tasks. If the number does not change, continue to monitor. If the number changes, update the picture book list data and read the background data (image or video based on multiple frames of images) of the first picture book in the picture book list as the background of the picture book application homepage.

[0340] On the homepage of the picture book application, when the user clicks on a picture book, the process of displaying and playing the picture book content of the picture book can be entered.

[0341] On the target application homepage, combine Figure 6 As shown, when the user clicks on controls such as "AI content generation" to issue a media content generation instruction, a customized process is entered, such as displaying a media content generation input interface. After the user enters information content, the role selection page, the timbre selection page, and the painting style selection page are displayed in sequence to obtain the role identification, timbre identification, and painting style identification selected by the user, and based on the role identification obtained on the role selection page, the timbre identification obtained on the timbre selection page, the painting style identification obtained on the painting style selection page, and the information content received by the information input component, a media content generation instruction is generated to send to the server so that the server generates the corresponding media content. It can be understood that in other embodiments, the display content of the control that issues the media content generation instruction can also be set in other ways.

[0342] On the target app home page, when the user clicks the Settings button, for example Figure 6 The middle control 602 can enter the setting process for the target application.
