Alternatively, the user can input user commands by inputting specific sound or gesture, and then the user input interface receives the user input commands by identifying the sound or gesture through the sensor.

[0077] In some embodiments, a "user interface" is a medium interface for interaction and information exchange between an application program or an operating system and a user, which realizes the conversion between the internal form of information and the form that the user can accept. The commonly used form of the user interface is a graphic user interface (GUI), which refers to a user interface related to computer operation displayed in a graphical manner.

[0078] In some embodiments, the system of the display device can include a kernel, a shell, a file system and an application program. The kernel, the shell and the file system together constitute a basic operating system structure, which allows the user to manage files, run programs and use the system. After power-on, the kernel starts, activates the kernel space, abstracts hardware, initializes hardware parameters, etc., runs and maintains virtual memory, scheduler, signals and inter-process communication (IPC). After the kernel starts, the shell and the user application program are loaded. The application program is compiled into machine code after starting, forming a process.

[0079] As shown in Figure 4 , the system of the display device can include a kernel, a shell, a file system and an application program. The kernel, the shell and the file system together constitute a basic operating system structure, which allows the user to manage files, run programs and use the system. After power-on, the kernel starts, activates the kernel space, abstracts hardware, initializes hardware parameters, etc., runs and maintains virtual memory, scheduler, signals and inter-process communication (IPC). After the kernel starts, the shell and the user application program are loaded. The application program is compiled into machine code after starting, forming a process.

[0080] As shown in Figure 4 , the system of the display device is divided into three layers from top to bottom, namely an application layer, a middleware layer and a hardware layer.

[0081] The application layer mainly includes common applications on the television and an application framework. The common applications are mainly applications developed based on a browser, such as HTML5 APPs, and native applications (Native APPs);

[0082] An application framework is a complete program model that has all the basic functions required by standard application software, such as file access, data exchange, etc., as well as the user interface for these functions (toolbar, status bar, menu, dialog box).

[0083] Native apps can support online or offline access, push notifications, or access to local resources.

[0084] The middleware layer includes various television protocols, multimedia protocols, and system components. Middleware can use the basic services (functions) provided by system software to connect different parts of application systems or different applications on the network, achieving resource sharing and function sharing.

[0085] The hardware layer mainly includes the HAL interface, hardware, and drivers. The HAL interface is a unified interface for all TV chips, with the specific logic implemented by each chip. The drivers mainly include: audio drivers, display drivers, Bluetooth drivers, camera drivers, Wi-Fi drivers, USB drivers, HDMI drivers, sensor drivers (such as fingerprint sensors, temperature sensors, pressure sensors, etc.), and power drivers.

[0086] In this embodiment, the display device can play video data. When a video control is displayed on the user interface, the user can select the video control using a control device, causing the display device to play the video data corresponding to the video control.

[0087] For example, such as Figure 5 As shown in ①, the user moves the focus to the video A control (with a thickened border) using the control device and presses the confirmation button on the control device to generate a command to select the video control. The user interface then jumps to the following... Figure 5 The user interface is shown in ②. It should be noted that in this embodiment, moving the focus to a control can thicken the control's border. Alternatively, other forms can be used to indicate that the control is selected. For example, when the focus moves to a control, the control can change its shape, such as from a square to a circle. Alternatively, when a control is selected, it can be enlarged according to a preset ratio. For instance, if the display area of ​​video controls on the user interface is the same, when a control is selected, its display area increases by 1.2 times compared to the original control's display area. Since this application does not restrict the shape of the control when the focus is on it, other forms that facilitate user identification of selected video controls are acceptable.

[0088] Before playing the video data corresponding to the video control on the user interface, the corresponding video data needs to be obtained from the server. Since the same audio and video pushing scheme is currently used when sending video data from the server to the display device, a lot of bandwidth may be wasted, because the same audio and video pushing scheme is used without considering the difference in the playing capability of the display device. If the currently used display device can support the H.265 encoding protocol, the H.265 encoding protocol has a higher compression ratio than the H264 encoding protocol, and in the case of the same bandwidth, a higher definition video can be played. In the related art, in order to ensure the usability of old display device models, the same scheme of pushing video data of the H.264 encoding protocol is still used, which causes a lot of network resource consumption and waste of network resources.

[0089] It should be noted that H.264 is an abbreviation of MPEG-4 AVC (Advanced Video Codec). H.264 and H.265 are both video compression standards and are also widely used high-precision video recording, compression and publishing formats. H.265 (HEVC, High Efficiency Video Coding) is a new generation of video coding technology. It retains some technologies of the existing video coding standard H.264 and uses new technologies to improve and optimize some aspects. The new technology uses advanced techniques to improve the relationship between code stream, encoding quality, delay and algorithm complexity to achieve optimal settings. Specific contents include: improving compression efficiency, improving robustness and error recovery capability, reducing real-time delay, reducing channel acquisition time and random access delay, and reducing complexity. The core advantage of H.265 is that it can significantly reduce the compression code rate under the same image quality compared to previous generations of standards. In terms of objective effect improvement, according to the test, H.265 reduces the code rate by about half at 1080P resolution, and the higher the resolution, the more significant the advantage.

[0090] To solve the above technical problems, the embodiments of the present application provide a method for playing a video in a display device, which obtains video data corresponding to the playing capability of the display device from a server to reduce the bandwidth required when obtaining the video data as much as possible. The method, as shown in Figure 6 includes:

[0091] When at least one video control is displayed on the user interface, a command for selecting the video control is received, and a first request command carrying a device identifier is sent to the server.

[0092] In the embodiments of the present application, there are many scenarios in which the user interface displays video controls, for example, when the display device is powered on, the home application of the display device is started, the display device displays the user interface of the home application, and the user interface displays video controls. The video corresponding to the video controls can be a movie, a TV series, etc. The user can select the video controls through the control device.

[0093] In addition, the user interface can also display video controls in other scenarios, for example, the second-level page of the home application can also display video controls. The first-level page of the home application displays column categories, including a movie column and a TV series column. There are movie category controls and TV category controls. When the user selects the movie category controls, the user interface jumps to the second-level page corresponding to the movie category controls. The second-level page includes a plurality of video controls, and each video control corresponds to a movie. Figure 7 As shown in FIG. 1, the first-level page displays TV category controls, movie category controls, and cartoon category controls. The user can move the focus to the movie category controls and press the confirmation key on the control device. The user interface jumps to the second-level page as shown in FIG. 2. Figure 7 As shown in FIG. 2, the second-level page displays a plurality of movie controls. The user can move the focus to the movie A controls and play the movie corresponding to the movie A controls.

[0094] In the embodiments of the present application, the device identifier corresponds to the display device, and the display device has a unique device identifier. The present application does not limit the specific form of the device identifier. For example, the device identifier can include one or more of numbers, letters, and symbols.

[0095] The server receives the first request instruction sent by the display device and carrying the device identifier, and finds the playing capability corresponding to the display device according to the device identifier. The playing capability refers to the encoding protocol supported by the display device, which can be H.264 or H.265.

[0096] In some embodiments, the server itself stores a storage list of device identifiers and playing capabilities. Of course, the device identifier and the playing capability can also not be stored in the form of a list, which is not limited herein. When receiving the first request instruction, the server filters the playing capability corresponding to the same device identifier as the device identifier in the first request instruction from the storage list. The storage list is shown in Table 1. The device identifier carried by the first request instruction is 001, and the playing capability found by the server at this time is H.264.

[0097] Table 1

[0098] Device identification Playability 001 H.264 002 H.265 003 H.265

[0099] In some other embodiments, the storage list is not stored in the server, but is stored in a storage device connected to the server, and the storage device stores the storage list of the device identifiers and the playing capabilities. When the server receives the first request instruction, the storage device is searched to find the playing capability corresponding to the device identifier in the first request instruction.

[0100] After the server finds the playing capability of the display device, the server sends the playing capability to the display device. The display device acquires the index file from the server according to the playing capability and the video identifier corresponding to the video control.

[0101] In the embodiments of the present application, the number of index files of each video is determined according to the number of types of playing capabilities. For example, the playing capability of all display devices currently supports H.265 or H.264, and the number of types of playing capabilities is two. In this case, there are two index files for each video, one of which corresponds to the playing capability supporting H.265, and the other of which corresponds to the playing capability supporting H.264. Each index file contains video data addresses of different resolutions. For example, index file A contains a video data address A of 720P resolution under H.265 encoding protocol and a video data address B of 1080P resolution under H.265 encoding protocol, and index file B contains a video data address C of 720P resolution under H.264 encoding protocol and a video data address D of 1080P resolution under H.264 encoding protocol. In some embodiments, the index file is stored in the server. In some other embodiments, the index file is stored in the storage device, and the server finds the corresponding index file from the storage device and sends it to the display device.

[0102] In some embodiments, the step of acquiring the index file from the server according to the playing capability and the video identifier corresponding to the video control comprises the following steps: finding all index files of the corresponding video according to the video identifier, and then determining a unique index file according to the playing capability.

[0103] In some embodiments, the index file corresponds to an index file address, and the index file address corresponds to the video identifier and the playing capability one by one. The server no longer directly searches for the index file according to the video identifier and the playing capability, but searches for the corresponding index file address, and then searches for the corresponding index file according to the index file address.

[0104] In some other embodiments, the step of acquiring the index file from the server according to the playing capability and the video identifier corresponding to the video control comprises the following steps: Figure 8The method further includes: sending a sixth request instruction carrying a playing capability and a video identifier corresponding to a video control to the server, so that the server issues an index file address found according to the playing capability and the video identifier; and sending a seventh request instruction carrying the index file address to the server, so that the server issues an index file corresponding to the index file address.

[0105] In some embodiments, the method further includes determining a to-be-played resolution of the to-be-played video data. In some embodiments, when the instruction of selecting the video control is received, the to-be-played resolution of the to-be-played video data is a preset resolution, and the preset resolution is one of resolutions in the index file. When a user watches a video by using a display device, the user selects a video control corresponding to a video desired to be watched by using a control device, and the preset resolution is used to play the video when the video is played. For example, the preset resolution can be 720P.

[0106] The method further includes screening a video data address corresponding to the to-be-played resolution from the index file. In an embodiment of the application, the index file includes resolutions and video data addresses corresponding to the resolutions, and the video data address corresponding to the to-be-played resolution is found from the index file.

[0107] The method further includes sending a second request instruction carrying the video data address to the server, and the server receives the second request instruction and issues video data corresponding to the video data address to the display device. In an embodiment of the application, the video data address is found from the index file corresponding to the playing capability of the display device, and the video data corresponding to the video data address meets the playing capability of the display device. For example, the display device supports an H.265 encoding protocol, and in this embodiment, the index file corresponds to the encoding protocol, and the video data corresponding to the video data address in the index file corresponds to the encoding protocol. Therefore, the video data received by the display device can be video data under the H.265 encoding protocol. The H.265 encoding protocol has a higher compression ratio than the H264 encoding protocol, and in the case of the same bandwidth, the video can be played in a higher definition. Therefore, the video data transmitted can reduce the occupation of network resources as much as possible while still being able to see clear video. Through this adaptive capability, bandwidth waste caused by improving compatibility can be avoided. If the display device supports the H.265 encoding protocol, and the server still issues video data under the H.264 encoding protocol, and the H.264 encoding protocol video data has a low compression ratio. Therefore, the problem that the video data cannot be used for improving bandwidth utilization can occur.

[0108] The display device decodes the video data and plays the decoded video data. In the embodiment of the present application, the video data found by the server is encoded data encoded according to the playing capability. After the encoded video data is sent from the server to the display device, the display device decodes the video data and plays the decoded video data.

[0109] In the decoding process, the display device can fail to decode. This is because when the server fails to successfully find the playing capability of the display device, the playing capability sent to the display device can be null. When the display device receives the playing capability as null, the playing capability is automatically assigned a value. For example, the display device assigns the playing capability as H.265. The display device acquires an index file from the server according to the assigned playing capability and the video identifier corresponding to the video control. It can be understood that the acquired index file corresponds to the H.265 encoding protocol. Finally, the video data sent by the server to the display device is video data under the H.265 encoding protocol. The playing capability of different display devices can be different. At this time, the display device can support the H.264 encoding protocol but not the H.265 encoding protocol, and thus the decoding fails.

[0110] In the embodiment of the present application, if the decoding of the video data fails, the playing capability of the display device is re-determined. The re-determined playing capability is different from the playing capability requested from the server. For example, the playing capability includes two types, one is to support the H.265 encoding protocol, and the other is to support the H.264 encoding protocol. At this time, the playing capability is automatically assigned from the H.265 encoding protocol to the H.264 encoding protocol, and then the step of acquiring an index file from the server according to the playing capability and the video identifier corresponding to the video control is repeatedly executed. At this time, the acquired index file corresponds to the H.264 encoding protocol. The display device can find the video data address from the index file corresponding to the H.264 encoding protocol. At this time, the video data corresponding to the video data address acquired from the server is video data under the H.264 encoding protocol, and the display device can decode successfully.

[0111] In this way, when the video data sent by the server to the display device cannot be decoded, the user can also watch the video corresponding to the video control. When the sent video data is video data under the H.265 encoding protocol and the display device cannot decode successfully, the H.264 encoding protocol video data is acquired through the above operation, so that the display device can normally decode and play. In this way, the compression ratio of the H.265 encoding can be maximized, and the bandwidth can be fully utilized. Only in the case of not supporting, the request for downloading the audio and video of the H.264 playing capability is re-initiated.

[0112] In some embodiments, the method further comprises: obtaining a resolution list from the server according to the playing capability and the video identifier corresponding to the video control, wherein the resolutions in the resolution list are the same as the resolutions in the index file.

[0113] In the embodiments of the present application, the resolution list is also downloaded from the server, and when it is identified that the video is playing with lag, a resolution corresponding to the current bandwidth is selected from the resolution list. For example, the identification of the video playing with lag can be completed by the browser installed in the display device. When the video is playing with lag, the bandwidth of the current network is determined, the resolution of the playing video is determined according to the current bandwidth, and the resolution of the playing video needs to be reduced at this time. In the embodiments of the present application, the method of determining the corresponding resolution according to the bandwidth includes various methods, which will not be described here.

[0114] The video data address corresponding to the resolution selected according to the bandwidth is found from the index file; a third request instruction carrying the video data address is sent to the server, and the server issues the video data corresponding to the video data address according to the third request instruction. The display device decodes the video data and plays the decoded video data. In the embodiments of the present application, when the video is playing with lag, the corresponding resolution is adaptively selected according to the bandwidth, and the video data address corresponding to the resolution is found from the index file. In this way, the video data is reacquired according to the video data address, and the reacquired video data is played. Since the resolution of the video data is low, the bandwidth occupied is small, and the video can be played smoothly.

[0115] In some embodiments, during the video playing process, a display instruction of the resolution list is received, and the resolution list is controlled to be displayed. For example, as shown in Figure 9 , in Figure 9 , the user interface displays that the resolution of the currently playing video data is high definition. The user can use the control device to move the focus to the resolution control, i.e., the “high definition” control (the frame is thickened), and press the confirmation key on the control device to generate a display instruction of the resolution list. When the display instruction of the resolution list is received, the resolution list is controlled to be displayed on the user interface, as shown in Figure 10 , the resolution list includes a smooth control, a clear control, a 720P control and a 1080P control. In some embodiments, the resolution corresponding to the smooth control is 240P, and the resolution corresponding to the clear control is 360P.

[0116] In some embodiments, the resolution list displayed on the user interface is determined according to the highest displayable resolution of the display device. When the highest resolution in the resolution list sent by the server is 4k, and the highest displayable resolution of the display device is 2k, the highest resolution of the resolution list displayed on the user interface is determined to be 2k. The process of determining the resolution list displayed on the user interface can be completed in the server or in the display device. When it is completed in the server, the highest displayable resolution of the display device is sent to the server, and the server processes the stored resolution list according to the highest displayable resolution. After deleting the content higher than the highest displayable resolution, the resolution list is sent to the display device for display. When it is completed in the display device, the unprocessed resolution list sent by the server is sent to the display device, and compared with the highest displayable resolution of the display device. After deleting the content higher than the highest displayable resolution, the resolution list is displayed on the user interface.

[0117] For example, in the above embodiment, the user moves the focus to the 720P control through the keys on the control device, and presses the confirmation key on the control device. At this time, the instruction of selecting the resolution control in the resolution list is generated, the video data address corresponding to the resolution 720P is screened out in the index file, sent to the server, and the video data corresponding to the video data address is sent by the server. The video data is played after being successfully decoded, and the resolution of the video data is 720P. Figure 10 In some embodiments, the resolution list including the resolution control further includes a cancel control. When the user selects the cancel control through the keys on the control device, the resolution list is controlled to no longer be displayed.

[0118] In some embodiments, the resolution list displayed on the user interface is determined according to the highest displayable resolution of the display device. When the highest resolution in the resolution list sent by the server is 4k, and the highest displayable resolution of the display device is 2k, the highest resolution of the resolution list displayed on the user interface is determined to be 2k. The process of determining the resolution list displayed on the user interface can be completed in the server or in the display device. When it is completed in the server, the highest displayable resolution of the display device is sent to the server, and the server processes the stored resolution list according to the highest displayable resolution. After deleting the content higher than the highest displayable resolution, the resolution list is sent to the display device for display. When it is completed in the display device, the unprocessed resolution list sent by the server is sent to the display device, and compared with the highest displayable resolution of the display device. After deleting the content higher than the highest displayable resolution, the resolution list is displayed on the user interface.

[0119] Since the embodiment of the present application involves the index file, the index file includes the resolution and the video data address corresponding to the resolution. The video data corresponding to the video data address is made from the original video data according to different resolutions and the playing ability of the display device. For self-operated videos, the video data can be made according to different resolutions and the playing ability, but for non-self-operated videos, the video data cannot be made. In some embodiments, before the first request instruction is sent to the server, it is judged whether the video corresponding to the selected video control is a self-operated video, and the method further includes:

[0120] When the user interface including the video control is displayed, a seventh request instruction carrying a video identification corresponding to the video control is sent to the server, so that the server issues video information corresponding to each video identification, and the video information is used to distinguish self-operated videos and non-self-operated videos. In the embodiment of the application, when the video control is displayed, the video information corresponding to all video controls on the user interface is obtained from the server. The video identification is used to indicate a video, and each video has a unique video identification. The instruction of selecting the video control is received, and if the video information corresponding to the video control indicates that the video is a self-operated video, the step of sending the first request instruction to the server is executed.

[0121] In the embodiment of the application, when the instruction of selecting the video control is received, the video information corresponding to the video control is filtered from the video information obtained from the server. If the video information indicates that the video is a self-operated video, it is indicated that the video has a corresponding index file. If the video information indicates that the video is a non-self-operated video, it is indicated that the video does not have a corresponding index file. Therefore, it is meaningless to send the first request instruction to the server to perform subsequent operations. Therefore, when the video information indicates that the video is a non-self-operated video, a video data request carrying the video identification is sent to the server. The server receives the request and issues the video data, and the step of sending the first request instruction to the server is not performed.

[0122] In some embodiments, before the first request instruction is sent to the server, it is judged whether the display device can execute the method in the embodiment of the application. The method further includes sending a verification request carrying verification information to the server, and the server issues a verification result obtained by verifying the display device according to the verification information. If the verification result is verification success, the step of sending the first request instruction to the server is executed. In the embodiment of the application, the verification information is a KEY value. The KEY value is used to verify whether the display device can execute the method in the embodiment of the application. Specifically, when the verification is successful, the first request instruction is sent to the server. If the verification fails, the first request instruction is not sent to the server.

[0123] In some embodiments, the display device further comprises a browser, a TV middleware and a download agent, the browser is responsible for foreground display page, streaming download and video playback control, etc. In case of playback problem caused by decoding failure, the browser application needs to be able to retry playback. The browser plug-in provides an interface for the download agent, such as reporting the playback capability of the TV platform, receiving resolution, starting / stopping download, etc. The TV middleware provides information such as software / hardware version and device identification of the TV platform. The download agent is responsible for stream download and encoding, etc. It can report the device identification according to the device identification provided by the browser. It can generate streams of different resolutions and different encodings according to the playback capability of the display device provided by the server. The server provides the playback capability corresponding to the TV platform and provides streaming service.

[0124] In some embodiments, before sending the first request instruction to the server, the method further comprises: Figure 11

[0125] When displaying the user interface comprising the video control, the browser is controlled to send a seventh request instruction carrying a video identifier corresponding to the video control to the server, so that the server sends video information corresponding to each video identifier to the browser.

[0126] The instruction of selecting the video control is received, and the browser is controlled to determine whether the video information corresponding to the video control indicates that the video is a self-operated video. If the video information corresponding to the video control indicates that the video is a self-operated video, the browser is controlled to notify the download agent by using the browser plug-in, so that the download agent sends a verification request carrying verification information to the server, and receives a verification result of verifying the display device according to the verification information fed back by the server.

[0127] The download agent is controlled to determine whether the verification result is verification success. If the verification result is verification success, the download agent is controlled to send a get request to the TV middleware, so that the TV middleware feeds back the device identification. The download agent is controlled to execute the step of sending the first request instruction to the server.

[0128] It should be noted that the order of the verification information verification step and the step of obtaining the video information in the embodiments of the present application can not be in sequence, or the display device can be verified first, and then the video information is obtained when the verification is successful.

[0129] ​In the embodiment, the download agent receives the playing capability sent by the server according to the first request instruction, and acquires the index file through the server according to the video identifier and the playing capability. The download agent determines the to-be-played resolution of the to-be-played video data, searches the corresponding video data address in the index file, sends the second request instruction carrying the video data address to the server, the server issues the corresponding video data, the browser decodes the video data, and if the decoding is successful, the decoded video data is played.

[0130] In the above embodiments, a playing method of a video in a display device and the display device, the method acquires video data corresponding to the playing capability of the display device from a server, and reduces the bandwidth requirement as much as possible when acquiring the video data. The method comprises: receiving an instruction of selecting a video control, sending a first request instruction carrying a device identifier to a server, so that the server issues a playing capability corresponding to the device identifier, wherein the playing capability refers to an encoding protocol supported by the display device; acquiring an index file through the server according to the playing capability and a video identifier corresponding to the video control, wherein the index file comprises a video data address corresponding to at least one resolution of a video corresponding to the video identifier; determining a to-be-played resolution of to-be-played video data; screening out a video data address corresponding to the to-be-played resolution in the index file; sending a second request instruction carrying the video data address to the server, so that the server issues video data corresponding to the video data address; decoding the video data, and playing the video data whose decoding is successful.
