[0006] When the media content in the video format is generated, obtaining an acquisition link of the media content in the target format;

[0007] In response to an instruction to obtain the media content in a target format, displaying a graphic code in a user interface of the target application through the display; the graphic code includes a link to obtain the media content in the target format;

[0008] Among them, the target format is different from the video format; the media content in the target format includes some pictures from the media content in the video format; and the some pictures are determined according to the text carrying form of the media content in the video format.

[0009] Technical effect: After the display device completes the generation of media content in video format and obtains media content in video format, it can convert the media content in video format into media content in target format, obtain an acquisition link for the media content in target format, and provide a graphic code containing the acquisition link for the media content in target format, so that users can scan and download the media content in target format through mobile terminals and other devices. The target format is different from the video format. The media content in the target format contains some pictures from the media content in video format. Therefore, the display device does not need to make all pictures of the media content into media content in target format, thereby reducing the amount of transmitted data, and the part of the pictures extracted by the display device is determined according to the text carrying form of the media content in video format to protect the integrity of the media content information.

[0010] In some embodiments of the present application, the display device further includes:

[0011] communication devices;

[0012] The controller is further configured to:

[0013] generating the media content in a target format according to the partial pictures of the media content in a video format;

[0014] sending the media content in a target format to a server via the communication device;

[0015] The acquisition link sent by the server is received through the communication device; the acquisition link is generated by the server according to the media content in the target format.

[0016] Technical effect: The display device can generate media content in a target format based on a partial picture of media content in a video format, thereby converting media content in a video format into media content in a target format, and upload the media content in the target format to a server to obtain an acquisition link for the media content in the target format fed back by the server, so that the display device can display the acquisition link for the user to obtain the media content in the target format from the server based on the acquisition link through its mobile terminal or other device, so that the acquisition of the media content in the target format by the mobile terminal or other device does not need to be limited by the storage performance of the display device itself.

[0017] In some embodiments of the present application, the controller is further configured to: if the text carrying form is the first form, obtain the partial picture according to the target sampling period.

[0018] Technical effect: When the text is carried in the first form, the display device can extract pictures from the media content in the video format through a certain sampling period, and form partial pictures efficiently and conveniently.

[0019] In some embodiments of the present application, the controller is further configured to: if the media content in video format does not have an audio track, perform text recognition on the image sequence of the media content in video format; if the text recognition result indicates that the media content in video format does not contain images with text, determine that the text carrying form is the first form.

[0020] Technical effect: It is possible to first determine whether the media content in video format has an audio track, and then perform text recognition on the image sequence of the media content in video format if there is no audio track. If the media content is not found to contain images with text, the text carrying form is identified as the first form, thereby accurately distinguishing between the two text carrying forms: the text has an independent audio track and the text has text but is embedded in the video.

[0021] In some embodiments of the present application, the controller is further configured to:

[0022] If the text carrying form is the second form, the partial picture is obtained according to the picture similarity between two pictures of the media content in video format.

[0023] Technical effect: When the text carrying form is the second form, the display device can obtain a partial image according to the image similarity between two images, so that the partial image can be effectively extracted to form media content in the target format based on whether the two images are similar, so as to protect the integrity of the media content information while reducing the amount of transmitted data.

[0024] In some embodiments of the present application, the controller is further configured to:

[0025] If the picture similarity between the first picture and the second picture of the two pictures is less than a threshold, the second picture is determined as one of the partial pictures; and the first picture belongs to the partial pictures.

[0026] Technical effect: The display device can sequentially determine whether the image similarity of two images is less than a threshold value. If so, the second image can be determined as one of the partial images and the second image can be used as a reference to continue to determine until the last image in the image sequence of the media content, thereby accurately completing the extraction of partial images when the text carrying form is the second form.

[0027] In some embodiments of the present application, the controller is further configured to:

[0028] If the media content in video format has an audio track, the text carrying form is determined to be the second form.

[0029] Technical effect: It is possible to first determine whether the media content in video format has an audio track. If it has an audio track, the text-carrying form can be directly identified as the second form, and quickly distinguished from the two text-carrying forms: one without text and one with text but embedded in the video.

[0030] In some embodiments of the present application, the controller is further configured to:

[0031] If the text carrying form is the third form, the partial picture is obtained according to the text consistency and picture similarity between two pictures of the media content in video format.

[0032] Technical effect: When the text carrying form is the third form, the display device can obtain a partial image based on the text consistency and image similarity between two images, so as to consider in turn whether the text between the two images is consistent and whether the two images are similar, and accurately and effectively extract the partial image to form the media content of the target format, so as to protect the integrity of the media content information while reducing the amount of transmitted data.

[0033] In some embodiments of the present application, the controller is further configured to:

[0034] If the text consistency between the first picture and the second picture of the two pictures is inconsistent, the second picture is determined as one of the partial pictures; the first picture belongs to the partial pictures; if the text consistency is consistent, the partial picture is obtained according to the picture similarity between the first picture and the second picture.

[0035] Technical effect: The display device can perform a mixed verification of text and image similarity for two images. It can first determine whether the text of the first image is consistent with that of the second image. If not, the second image can also be determined as one of the partial images. If the text of the two images is consistent, the partial image can be further obtained based on the similarity of the two images. In this way, when the text carrying form is a third form, it can be determined in turn based on the text consistency and image similarity whether to extract the image to form media content in the target format, so as to protect the integrity of the media content information while reducing the amount of transmitted data.

[0036] In some embodiments of the present application, the controller is further configured to:

[0037] If the text consistency is consistent, and the picture similarity between the first picture and the second picture is less than a threshold, the second picture is determined as one of the partial pictures.

[0038] Technical effect: When the text carrying form is the third form, if the display device determines that the text of the first picture is consistent with that of the second picture, the display device can further determine the second picture as one of the partial pictures when the picture similarity between the first picture and the second picture is less than a threshold. In this way, even if two pictures correspond to the same text, they can be used to form media content in a target format when the pictures change to a certain extent, so as to protect the integrity of the media content information while reducing the amount of transmitted data.

[0039] In some embodiments of the present application, the controller is further configured to:

[0040] If the media content in video format does not have an audio track, text recognition is performed on the image sequence of the media content in video format; if the text recognition result indicates that the media content in video format contains images with text, the text carrying form is determined to be the third form.

[0041] Technical effect: It is possible to first determine whether the media content in video format has an audio track, and then perform text recognition on the image sequence of the media content in video format if there is no audio track. At this time, as long as one of the images is recognized to have text, it can be determined that the text-carrying form is the third form, thereby being able to efficiently distinguish between the two text-carrying forms of no text and text-carrying forms with an independent audio track.

[0042] In some embodiments of the present application, the target format includes a portable file format.

[0043] Technical effect: The display device can provide users with a link to obtain media content in a portable file format. The media content in a portable file format has strong compatibility and convenience, which facilitates the dissemination of media content.

[0084] The power supply 180 is used to provide operating power support for each component of the control device 100 under the control of the controller.

[0085] In order to perform user interaction, in some embodiments, the display device 200 may run an operating system. The operating system is a computer program for managing and controlling hardware resources and software resources in the display device 200. The operating system may provide a user interface (control the display device), allow the user to interact with the display device 200, and support the running of various application programs.

[0086] It should be noted that the operating system may be a native operating system based on a specific operating platform, or a third-party operating system deeply customized based on a specific operating platform, or an independent operating system specially developed for the display device.

[0087] The operating system can be divided into different modules or levels according to the functions implemented. For example, as shown in Figure 4, in some embodiments, the system is divided into four layers, from top to bottom, namely, the application layer (Applications layer) (referred to as "application layer"), the application framework layer (Application Framework layer) (referred to as "framework layer"), the system library layer and the kernel layer.

[0088] In some embodiments, the application layer is used to provide services and interfaces for applications so that the display device 200 can run applications and interact with users based on applications. At least one application can be run in the application layer, and these applications can be window programs, system settings programs, clock programs, etc. that come with the operating system; they can also be applications developed by third-party developers. In specific implementations, the application packages in the application layer are not limited to the above examples.

[0089] The framework layer provides application programming interfaces (APIs) and programming frameworks for applications. The application framework layer includes some predefined functions. The application framework layer is equivalent to a processing center that determines the actions of applications in the application layer. Applications can access system resources and obtain system services during execution through the API interface.

[0090] As shown in FIG4 , the application framework layer in the embodiment of the present application includes a view system, managers, content providers, etc., wherein the view system can design and implement the interface and interaction of the application, and the view system includes lists, grids, text boxes, buttons, etc. The manager includes at least one of the following modules: an activity manager is used to interact with all activities running in the system; a location manager is used to provide system services or applications with access to system location services; a package manager is used to retrieve various information related to the application package currently installed on the device; a notification manager is used to control the display and clearing of notification messages; and a window manager is used to manage icons, windows, toolbars, wallpapers, and desktop widgets on the user interface.

[0091] In some embodiments, the activity manager is used to manage the life cycle of each application and the usual navigation back function, such as controlling the exit, opening, and back of the application. The window manager is used to manage all window programs, such as obtaining the display screen size, determining whether there is a status bar, locking the screen, capturing the screen, and controlling the display window changes, for example, reducing the display window, shaking the display, distorting the display, etc.

[0092] In some embodiments, the system runtime layer can provide support for the framework layer. When the framework layer is used, the operating system will run the instruction library contained in the system runtime layer, such as the C / C++ instruction library, to implement the functions to be implemented by the framework layer.

[0093] In some embodiments, the kernel layer is a functional layer between the hardware and software of the display device 200. The kernel layer can implement functions such as hardware abstraction, multitasking, and memory management. For example, as shown in FIG4 , a hardware driver can be configured in the kernel layer, and the driver included in the kernel layer can be at least one of the following drivers: an audio driver, a display driver, a Bluetooth driver, a camera driver, a WIFI driver, a USB driver, an HDMI driver, a sensor driver (such as a fingerprint sensor, a temperature sensor, a pressure sensor, etc.), and a power driver, etc.

[0094] It should be noted that the above example is only a simple division of the operating system functions and does not constitute a limitation on the specific operating system form of the display device 200 in the embodiment of the present application. 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.

[0095] In some embodiments, as shown in Figures 1 and 2, the present application provides a display device 200, which may include a display 260 and a controller 250, and the controller 250 is coupled to the display 260; wherein the display 260 is configured to display a user interface; the user interface at least includes a user interface of a target application.

[0096] As shown in FIG5 , the controller 250 is configured as follows:

[0097] Step 501: when the media content in the video format is generated, obtain a link for obtaining the media content in the target format.

[0098] Step 502, in response to an instruction to obtain media content in a target format, display a graphic code in a user interface of a target application through a display; the graphic code includes a link to obtain media content in a target format; wherein the target format is different from a video format; the media content in the target format includes some pictures from media content in a video format; and the some pictures are determined according to a text carrying form of the media content in a video format.

[0099] Among them, the target application can be a picture book application, and multiple picture books can be preset in the picture book application, and users can be supported to create new picture books. Each picture book includes multiple picture book pictures, and the character images in the multiple picture book pictures are unified; each picture book picture is generated based on a story text in the picture book story, and each picture book picture corresponds to a broadcast audio, which is obtained based on the story text corresponding to the picture book picture. Select a picture book in the picture book application and confirm the play, and the selected picture book can be played in video mode. During the picture book video playback process, the picture book picture can be a static display or have a sliding special effect. The picture book picture also displays the story text corresponding to the page picture, and the display duration of each picture book picture can correspond to the broadcast audio duration of the picture book picture. As an example, the switching display of two adjacent picture book pictures can be continuous, and the broadcast audio of two adjacent picture book pictures can be played at a distance of, for example, 1 second. There can be background music during the picture book playback process, and the background music matches the story content of the picture book.

[0100] The produced media content can be played through the display 260 of the display device 200, and the produced media content is presented in a video format on the display device 200. After the media content in the video format is produced, the controller 250 can obtain the media content in the video format and play it through the display 260.

[0101] The display device 200 may also provide a service for converting media content in a video format into media content in a target format. The target format may be a format for users to watch the media content on other terminals (such as the mobile terminal 300), so that users can watch the media content on other terminals. The target format is different from the video format. As an example, the target format may be a portable document format (PDF) or other formats.

[0102] When the media content in the video format is generated, the controller 250 can obtain the media content in the video format, and the controller 250 can also obtain the acquisition link of the media content in the target format. Among them, the acquisition link can be used for other terminals of the user (such as the mobile terminal 300) to obtain the media content in the target format. After obtaining the media content in the video format, the controller 250 can also display the acquisition entry of the media content in the target format through the user interface of the target application displayed on the display 260, and the acquisition entry can be used to provide the user with the acquisition service of the media content in the target format after the user triggers it.

[0103] The user can trigger the acquisition entry displayed on the user interface of the target application displayed on the display 260 by pressing a button of the control device 100 to send an acquisition instruction for the media content in the target format to the controller 250 of the display device 200 .

[0104] The controller 250 of the display device 200 responds to the acquisition instruction for the media content in the target format, and displays a graphic code containing the acquisition link of the media content in the target format in the user interface of the target application through the display 260. Among them, the graphic code can be a two-dimensional code, etc. As an example, the acquisition link can be displayed in the form of a two-dimensional code on the user interface of the target application of the display 260, and the user can obtain the media content in the target format by scanning the acquisition link in the form of a two-dimensional code through the mobile terminal 300. Among them, the media content in the target format includes some pictures from the media content in the video format, that is, it is not necessary to make all the pictures of the media content in the video format into the media content in the target format, which will result in a large amount of data to be transmitted and contain a large number of repeated pictures. For picture books, the pictures can be video frames of picture books in video format. Thus, the part of the pictures can be determined according to the text carrying form of the media content in the video format. Among them, the text carrying form refers to the carrying form of the text in the media content in the video format, which can include, for example, whether it carries text, what form the text exists in the media content in the video format, etc. For picture books, the text can be subtitles, and the text carrying form can be subtitles. Thus, the controller 250 can determine which pictures to extract and produce into the media content in the target format according to the text carrying form of the media content in the video format, thereby achieving the purpose of reducing the amount of data to be transmitted and protecting the integrity of the media content information.

[0105] According to the technical solution of this embodiment, after the display device completes the generation of the media content in the video format and obtains the media content in the video format, the media content in the video format can be converted into the media content in the target format, and an acquisition link of the media content in the target format and a graphic code containing the acquisition link of the media content in the target format can be obtained, so that the user can scan and download the media content in the target format through a mobile terminal or other device. The target format is different from the video format. The media content in the target format contains some pictures from the media content in the video format. Therefore, the display device does not need to make all the pictures of the media content into the media content in the target format, thereby reducing the amount of data transmitted, and the part of the pictures extracted by the display device is determined according to the text carrying form of the media content in the video format to protect the integrity of the media content information.

[0106] In some embodiments, as shown in FIG. 2 , the display device 200 may further include: a communication device 220. The controller 250 is further configured to:

[0107] Generate media content in a target format based on partial images of media content in a video format; send the media content in the target format to a server via a communication device; receive an acquisition link sent by the server via the communication device; the acquisition link is generated by the server based on the media content in the target format.

[0108] In this embodiment, after determining a partial picture of the media content in the video format, the controller 250 can generate the media content in the target format according to the partial picture, and then the controller 250 can send the media content in the target format to the server 400 through the communication device 220 for storage. After receiving the media content in the target format, the server 400 generates a corresponding acquisition link, and the server 400 returns the acquisition link to the display device 200. The communication device 220 of the display device 200 can receive the acquisition link sent by the server 400 and pass it to the controller 250, so that the controller 250 can display the acquisition link in the form of a graphic code such as a QR code on the user interface of the target application of the display 260, so that the user can scan the QR code through its mobile terminal 300, for example, and the server 400 provides a download service for the media content in the target format, and the user can download and obtain the media content in the target format through its mobile terminal 300, for example.

[0109] According to the solution of this embodiment, the display device 200 can generate media content in a target format based on a partial picture of media content in a video format, thereby converting the media content in a video format into media content in a target format, and uploading the media content in the target format to the server 400 to obtain an acquisition link for the media content in the target format fed back by the server 400, so that the display device 200 can display the acquisition link for the user to obtain the media content in the target format from the server 400 based on the acquisition link through its mobile terminal 300 or other devices, so that the acquisition of the media content in the target format by the mobile terminal 300 or other devices does not need to be limited by the storage performance of the display device 200 itself.

[0110] In some embodiments, the controller 250 is further configured to:

[0111] If the text carrying form is the first form, a portion of the image is acquired according to the target sampling period.

[0112] In this embodiment, the first form may be one of the multiple text carrying forms preset in the display device 200, or may be other text carrying forms not preset in the display device 200. The first form may include a form without text. In this regard, the controller 250 of the display device 200 may extract the portion of images from the media content in the video format according to the target sampling period. The target sampling period may be selected by the user or may be a sampling period set by the display device 200. The controller 250 may extract the portion of images according to the target sampling period and insert the images into the media content in the target format in the order in which they appear in the media content.

[0113] In the solution of this embodiment, the display device 200 can extract pictures from media content in a video format through a certain sampling period when the text carrying form is the first form, and form a partial picture efficiently and conveniently.

[0114] In some embodiments, the controller 250 is further configured to:

[0115] If the media content in video format does not have an audio track, text recognition is performed on the image sequence of the media content in video format; if the text recognition result indicates that the media content in video format does not contain images with text, the text carrying form is determined to be the first form.

[0116] Among them, the audio track can be an independent audio track in the media content in the video format. In this embodiment, the controller 250 can first determine whether the media content in the video format has an audio track. If the media content in the video format does not have an audio track, the controller 250 can perform text recognition on the image sequence of the media content in the video format, and can use OCR (Optical Character Recognition) to traverse each image in the image sequence of the media content in the video format. As an example, in the Android system, tools such as Firebase ML Kit or Tesseract OCR can be used to implement the OCR function. The controller 250 can thus obtain a text recognition result. If the text recognition result indicates that the media content in the video format does not contain a picture with text, the controller 250 can determine that the text carrying form of the media content in the video format is the first form, that is, the text carrying form of the media content in the video format can be a form without text.

[0117] The solution of this embodiment is: it is possible to first determine whether the media content in video format has an audio track, and if there is no audio track, perform text recognition on the picture sequence of the media content in video format. If the media content is not found to contain pictures with text, the text carrying form is identified as the first form, thereby accurately distinguishing between the two text carrying forms of having text and the text having an independent audio track and having text but the text being embedded in the video.

[0118] In some embodiments, the controller 250 is further configured to:

[0119] If the text carrying form is the second form, a partial picture is obtained according to the picture similarity between two pictures of the media content in the video format.

[0120] In this embodiment, the second form and the aforementioned first form belong to different text carrying forms. The second form may be one of the multiple text carrying forms preset in the display device 200. The second form may be a text carrying form with text and the text has an independent audio track. In this regard, the controller 250 of the display device 200 may obtain part of the pictures according to the picture similarity between two pictures of the media content in the video format. As an example, the picture similarity may be calculated by the mean square error (MSE) or the structural similarity index (SSIM) between the two pictures. Thus, the controller 250 may add the pictures with changed picture content to the media content in the target format in turn according to the judgment of the picture similarity between the two pictures, and may skip the pictures with unchanged picture content until the last frame is obtained to form the final media content in the target format.

[0121] In the scheme of this embodiment, the display device 200 can obtain a partial image according to the image similarity between two images when the text carrying form is the second form, so that the partial image can be effectively extracted to form media content in the target format based on whether the two images are similar, so as to protect the integrity of the media content information while reducing the amount of transmitted data.

[0122] In some embodiments, the controller 250 is further configured to:

[0123] If the picture similarity between the first picture and the second picture of the two pictures is less than a threshold, the second picture is determined to be one of the partial pictures; and the first picture belongs to the partial picture.

[0124] In this embodiment, the two pictures may include a first picture and a second picture, the first picture may be the previous picture, and the second picture may be the next picture. Among them, the first picture may be a picture that has been determined to be added to the media content of the target format, that is, the first picture belongs to a partial picture. In this regard, the picture similarity between the first picture and the second picture can be determined. If the picture similarity between the first picture and the second picture is less than a threshold value, it means that the picture content of the second picture has changed relative to the first picture, and the second picture can also be determined as one of the partial pictures, and then the second picture can be used as the basis for further judgment until the last frame is taken to form the final media content of the target format. Among them, if the picture similarity between the first picture and the second picture is greater than or equal to the threshold value, it means that the picture content of the second picture may not have changed relative to the first picture, so there is no need to use the second picture as one of the partial pictures, and then the second picture can be used as the basis for further judgment until the last frame is taken to form the final media content of the target format.

[0125] In the scheme of this embodiment, the display device 200 can determine in sequence whether the image similarity of two images is less than a threshold value. If so, the second image can be determined as one of the partial images and the second image can be used as a reference to continue to determine until the last image in the image sequence of the media content, thereby accurately completing the extraction of partial images when the text carrying form is the second form.

[0126] In some embodiments, the controller 250 is further configured to:

[0127] If the media content in the video format has an audio track, the text carrying form is determined to be the second form.

[0128] Wherein, the audio track can be an independent audio track in the media content of the video format. In the present embodiment, the controller 250 can first determine whether the media content of the video format has an audio track. If the media content of the video format has an audio track, the controller 250 can determine that the text carrying form of the media content of the video format is the second form.

[0129] In the scheme of this embodiment, the controller 250 can first determine whether the media content in video format has an audio track. If it has an audio track, it can directly identify the text carrying form as the second form, and quickly distinguish it from the two text carrying forms: one without text and the other with text but embedded in the video.

[0130] In some embodiments, the controller 250 is further configured to:

[0131] If the text carrying form is the third form, a partial picture is obtained according to text consistency and picture similarity between two pictures of the media content in the video format.

[0132] In this embodiment, the third form and the aforementioned first form and second form are different text carrying forms. The third form can be one of the multiple text carrying forms preset in the display device 200. The third form can be a text carrying form with text but the text is embedded in the video. In this regard, the controller 250 of the display device 200 can obtain part of the picture according to the text consistency and picture similarity between two pictures of the media content in the video format. That is, unlike the case of the second form, in the case of the third form, the judgment of text consistency is also added, that is, the part of the picture used to form the media content of the target format is obtained by a mixed verification method of text consistency and picture similarity. Among them, text consistency can be used to indicate whether the subtitles of the two pictures are consistent, which can include consistency and inconsistency. Therefore, in the case of the third form, the controller 250 of the display device 200 can consider the text consistency and picture similarity between the two pictures in turn to determine the picture of the media content added to the target format, and protect the integrity of the media content information as much as possible.

[0133] In the scheme of this embodiment, the display device 200 can obtain a partial image based on the text consistency and image similarity between two images when the text carrying form is the third form, so as to consider in turn whether the text between the two images is consistent and whether the two images are similar, and accurately and effectively extract the partial image to form the media content of the target format, so as to protect the integrity of the media content information while reducing the amount of transmitted data.

[0134] In some embodiments, the controller 250 is further configured to:

[0135] If the text consistency between the first picture and the second picture of the two pictures is inconsistent, the second picture is determined as one of the partial pictures; the first picture belongs to the partial picture; if the text consistency is consistent, the partial picture is obtained according to the picture similarity between the first picture and the second picture.

[0136] In this embodiment, the two pictures may include a first picture and a second picture, the first picture may be a previous picture, and the second picture may be a subsequent picture. Among them, the first picture may be a picture that has been determined to be added to the media content of the target format, that is, the first picture belongs to a partial picture. In this regard, the controller 250 may first determine the text consistency of the first picture and the second picture. If the text consistency of the first picture and the second picture is inconsistent, the controller 250 needs to determine the second picture as one of the partial pictures to be added to the media content of the target format. If the text consistency of the first picture and the second picture is consistent, the controller 250 needs to continue to determine the picture similarity of the first picture and the second picture, and determine whether to determine the second picture as one of the partial pictures according to the picture similarity of the two pictures. Thus, the controller 250 can add the picture with changed picture content to the media content of the target format according to the judgment of the picture similarity of the two pictures, when the text consistency of the two pictures is consistent, and can skip the picture with unchanged picture content. As an example, the image similarity may be calculated using a mean square error (MSE) or a structural similarity index (SSIM) between two images.

[0137] In the scheme of this embodiment, the display device 200 can perform a mixed verification of text and image similarity for two images. It can first determine whether the text of the first image is consistent with the second image. If not, the second image can also be determined as one of the partial images. If the text of the two images is consistent, the partial image can be further obtained based on the similarity of the two images. In this way, when the text carrying form is the third form, it can be determined in turn based on the text consistency and image similarity whether to extract the image to form the media content of the target format, so as to protect the integrity of the media content information while reducing the amount of transmitted data.

[0138] In some embodiments, the controller 250 is further configured to:

[0139] If the text consistency is consistent, and the image similarity between the first image and the second image is less than a threshold, the second image is determined as one of the partial images.

[0140] In this embodiment, when the text carrying form is the third form, if the controller 250 determines that the text consistency of the first picture and the second picture is consistent, it can continue to determine whether the image similarity between the first picture and the second picture is less than the threshold value. If the text consistency of the first picture and the second picture is consistent and the image similarity is less than the threshold value, the controller 250 can determine the second picture as one of the partial pictures. Among them, the first picture as mentioned above can be a picture of the media content that has been determined to be added to the target format, that is, the first picture belongs to a partial picture. Among them, when the text consistency of the first picture and the second picture is consistent, if the image similarity of the first picture and the second picture is less than the threshold value, it means that the picture content of the second picture has changed relative to the first picture. The controller 250 can also determine the second picture as one of the partial pictures, and then continue to judge backward based on the second picture, and the judgment includes the judgment of text consistency and image similarity until the last frame is taken to form the final media content of the target format. Among them, when the text consistency of the first picture is consistent with that of the second picture, if the image similarity between the first picture and the second picture is greater than or equal to a threshold, it means that the image content of the second picture may not have changed relative to the first picture, then there is no need to take the second picture as one of the partial pictures, and then the backward judgment can be continued based on the second picture, and the judgment also includes the judgment of text consistency and image similarity, until the last frame is taken to form the final media content in the target format.

[0141] In the solution of this embodiment, when the text carrying form is the third form, if the display device 200 determines that the text of the first picture is consistent with that of the second picture, the display device 200 can further determine the second picture as one of the partial pictures when the picture similarity between the first picture and the second picture is less than a threshold. In this way, even if two pictures correspond to the same text, they can be used to form media content in a target format when the pictures change to a certain extent, so as to protect the integrity of the media content information while reducing the amount of transmitted data.

[0142] In some embodiments, the controller 250 is further configured to:

[0143] If the media content in video format does not have an audio track, text recognition is performed on the image sequence of the media content in video format; if the text recognition result indicates that the media content in video format contains images with text, the text carrying form is determined to be the third form.

[0144] Among them, the audio track can be an independent audio track in the media content in video format. In this embodiment, the controller 250 can first determine whether the media content in video format has an audio track. If the media content in video format does not have an audio track, the controller 250 can perform text recognition on the image sequence of the media content in video format, and can use OCR (Optical Character Recognition) to traverse each image in the image sequence of the media content in video format. As an example, in the Android system, tools such as Firebase ML Kit or Tesseract OCR can be used to implement the OCR function. In this way, text recognition results can be continuously obtained each time a picture is recognized. If the text recognition result indicates that the media content in the video format contains pictures with text, the controller 250 can determine that the text carrying form of the media content in the video format is the third form, that is, the text carrying form of the media content in the video format can be a text carrying form with text but the text is embedded in the video, that is, in the recognition process of traversing the picture sequence of the media content in the video format, as long as a certain picture is recognized as having text, the recognition process can be exited, and it can be determined that the text carrying form of the media content in the video format is the third form.

[0145] The solution of this embodiment can first determine whether the media content in video format has an audio track, and if there is no audio track, perform text recognition on the image sequence of the media content in video format. At this time, as long as one of the images is recognized to have text, it can be determined that the text carrying form is the third form, thereby being able to efficiently distinguish between the two text carrying forms of no text and text carrying forms with independent audio tracks.

[0146] In some embodiments, the target format comprises a portable document format.

[0147] In this embodiment, the controller 250 of the display device 200 can convert media content in video format into media content in a portable file format, and then the controller 250 can send the media content in the portable file format to the server 400 for storage. After receiving the media content in the portable file format, the server 400 generates a corresponding acquisition link, and the server 400 returns the acquisition link to the display device 200. The controller 250 can display the acquisition link in the form of a QR code on the user interface of the target application of the display 260, so that the user can scan the QR code through its mobile terminal 300, for example. The server 400 provides a download service for the media content in the portable file format, and the user downloads and obtains the media content in the portable file format through its mobile terminal 300.

[0148] In the solution of this embodiment, the display device 200 can provide the user with a link to obtain the media content in a portable file format.

The target format is different from the video format. The media content in target format contains some pictures from the media content in video format. Therefore, the display device does not need to make all pictures of the media content into media content in target format, thereby reducing the amount of transmitted data, and the part of the pictures extracted by the display device is determined according to the text carrying form of the media content in video format to protect the integrity of the media content information.
