As shown in fig. 4, the system of the display device is divided into three layers, an application layer, a middleware layer, and a hardware layer, from top to bottom. In some embodiments, the system of the display device further includes a UI layer (not shown in the figure) located above the application layer, the UI layer receiving data transmissions of the application layer to enable a visual presentation of the display 260.

The application layer mainly comprises common applications on the television, and an application framework (Application Framework), wherein the common applications are mainly applications developed based on Browser, such as: HTML5 APPs; and native applications (native APPs);

the application framework (Application Framework) is a complete program model with all the basic functions required by standard application software, such as: file access, data exchange, and the interface for the use of these functions (toolbar, status column, menu, dialog box).

In some embodiments, the live television application may provide live television, broadcast television, through different signal sources. For example, a live television application may provide television signals using inputs from cable television, radio broadcast, satellite services, or other types of live television services. And, the live television application may display media data of the live television signal on the display device 200.

In some embodiments, the video on demand application may provide video from different storage sources. Unlike live television applications, video-on-demand provides media asset data from some storage sources. For example, video-on-demand may come from a server side of cloud storage or from a local hard disk storage containing stored video programs, etc.

In some embodiments, an application center may be provided to store various applications. The application may be a game, an application, or some other application associated with a computer system or other device but which may be run in a smart television. The application center may obtain these applications from different sources, store them in local storage, and then run on display device 200.

The display device 200 may play a variety of programs based on the above-described applications, such as a live television application or a video on demand application, etc. In some embodiments, different programs may correspond to different media asset types, and the programs of different media asset types may transmit media asset data based on different transmission modes. For example, the resource types may include Internet assets and non-Internet assets, the Internet assets being acquired based on Internet protocol information. The internet protocol information includes URL (Uniform Resource Locator ) addresses of programs. The display device 200 can acquire the media asset data of the program by accessing the URL address.

In order for display device 200 to obtain corresponding media data based on an application, as shown in fig. 5, in some embodiments, display device 200 may communicate with server 400 to implement data interactions. For example, the display apparatus 200 may transmit a request for acquisition of media asset data to the server 400 in response to an interactive instruction input by the user. The display device 200 controls the display 260 to display the corresponding media data according to the media data fed back by the server 400.

To facilitate data interaction between the display device 200 and the server 400, in some embodiments, the display device 200 needs to establish a communication connection with the server 400, and then interact with the server 400 through the established communication connection relationship. For example, the display device 200 and the server 400 may establish a communication connection through transmission networks of different transmission protocols, and transfer interactive data between the display device 200 and the server 400 through the transmission networks.

In some embodiments, it may be necessary to provide components for establishing a communication connection on the display device 200 and the server 400, respectively. That is, the communicator 220 may be provided in the display device 200, and the communication module may be provided in the server 400, and the communicator 220 and the communication module may simultaneously support at least one identical communication manner to establish a communication connection relationship. For example, the communicator 220 on the display device 200 includes a fiber optic interface, such that the display device 200 may connect to a network through the fiber optic interface; meanwhile, the communication module of the server 400 also includes an optical fiber interface, and the network may also be connected through the optical fiber interface, so as to implement communication connection between the display device 200 and the server 400.

It should be noted that, the display device 200 and the server 400 may also use other connection methods to establish a communication connection relationship. Such as wired broadband, wireless local area network, cellular network, bluetooth, infrared, radio frequency communications, etc.

A "many-to-one" connection may be between the display device 200 and the server 400, i.e., multiple display devices 200 may establish a communication connection with the same server 400, such that the server 400 may provide services to multiple display devices 200. The display device 200 and the server 400 may also be in a "many-to-many" connection relationship, i.e., the plurality of display devices 200 may establish communication with the plurality of servers 400, so that the plurality of servers 400 may respectively provide different services for the display device 200. It is obvious that in an individual application scenario, there may also be a "one-to-one" connection between the display device 200 and the server 400, i.e. one server 400 is dedicated to serve one display device 200.

In order to be able to provide services to the display device 200, a storage module may be further included in the server 400, and the storage module may store various resource data, information files, and control programs. In response to the user's interaction, the display device 200 may acquire different data in the storage module of the server 400, for example, the display device 200 may send a play data acquisition request to the server 400 when a certain media item is requested, and after receiving the request, the server 400 may extract the media data to be played in the storage module and transmit the media data to the display device 200, so that the display device 200 may decode and display the media data. The control program stored in the storage module may be executed by the control module of the server 400, so that the control module may perform a corresponding function according to the control program.

In this application, taking a live television program as an example, the display device 200 includes a plurality of broadcast channels with different frequency points, and each channel includes a plurality of sub-media assets with different playing times.

In playing live television programs, in some embodiments, the display device 200 may also record sub-media information in each channel in the display device 200 in real time, and then generate a program list according to the sub-media information played in each channel. For example, the display device 200 includes a channel DC a, a channel DC b, and a channel DC c. During a day, the channels DC a, DC b and DC c will live different programs, and then the program information to be played by the channels DC a, DC b, DC c is recorded in the program list of the display device 200.

In some embodiments, the list of programs requested by the display device 200 from the server 400 is an EPG (Electronic Progra m Guide ). The EPG is mainly composed of EIT (Event Information Table ) and ETT (Event Text Table, extended Text Table). The display device 200 may obtain the event information table EIT and the extended text table ETT of the EPG by parsing the MGT (Master Guide Tabl e, main guide table). The event information table EIT can provide event information of channels, and the extended text table ETT can provide detailed descriptions of the channels and the events. The EPG may combine sub-assets of all channels in the display device 200 together according to different classification rules. Thus, the user may cause the display device 200 to control the display 260 to play the corresponding sub-asset by selecting the asset item in EP G.

In addition, since the broadcast program can only be updated and played at a fixed time point, the program cannot be watched at the time point when the program is missed. Thus, in order to enhance the experience of the user, in some embodiments, a PVR (Personal Video Recorder ) function is provided in the display device 200, and the user can enable the PVR function to record the sub-assets of the specified channel for playback and viewing by the user. That is, the user may buffer the media asset data of the sub media asset to the display device 200 through the video recorder. The media data is cached by storing the media data in the memory 280 of the display device 200, and the memory 280 may be a storage medium such as a local disk of the display device 200, memory hardware, and the like.

For example, as shown in fig. 6, a user may set recording of sub-asset a in a certain channel through a PVR function to obtain a asset data stream of sub-asset a. And after finishing recording, automatically generating video data of the sub-media resource A according to the acquired media resource data stream. The video data is stored in the local memory of the display device 200 in the form of a local file, and the user can play back the sub-media asset a by selecting the video data of the sub-media asset a.

In some embodiments, the display device 200 needs to acquire the broadcast signal of the sub-asset while performing operations such as tuning, demodulation, and decoding on the broadcast signal to realize the transmission of the asset data. And saving the transmitted media data as a local file so as to play back the broadcast program by playing the local file. Wherein the process of tuning the broadcast signal is performed by the modem 210 of the display apparatus 200.

To increase the convenience of recording media, in some embodiments, the PVR functionality of the display device 200 includes a plurality of recording modes, such as timed recording, real-time recording, etc. The timing recording needs to set a fixed recording time, and after the set time is reached, the video recorder of the display device 200 is automatically started, and sub media assets are recorded within the set recording time; when the real-time recording reaches the playing time of the sub-media assets, the user manually controls the sub-media assets to be recorded.

However, the number of series programs with relevance such as a television series is limited, and if the series programs are to be recorded, real-time recording or timing recording time setting in advance of the playing sub-media assets is required in the time period of program update. However, since the broadcasting time of the program may be adjusted due to some factors, the timing recording may not be able to record the complete media content or record the wrong media content, which may further reduce the accuracy of recording.

Based on the above application scenario, in order to improve the problem of low recording accuracy in the display device 200, some embodiments of the present application provide a display device 200, as shown in fig. 7, including a display 260, a memory and a controller 250. Wherein the display 260 is configured to display a user interface; the memory 280 is configured to store video data, and the memory 280 may be a magnetic disk or storage hardware built in the display device 200, or may be a storage medium such as an external storage device connected to the display device 200; as shown in fig. 8, the controller 250 is configured to perform the following program steps:

s100: and searching a program list of the display device in response to the reserved recording instruction of the target media asset.

The display device 200 may play sub-assets for multiple channels based on different protocol stacks. The user may cause the display device 200 to record the target media asset for playback viewing by inputting a scheduled recording instruction of the target media asset to the display device 200. After receiving the scheduled recording instruction of the target media asset, the display device 200 searches the program list corresponding to the display device 200 in response to the scheduled recording instruction. The program list comprises media asset names and playing information of sub media assets. For example, the program list may be an EPG, the event information table EIT may be used to characterize a media asset name of a sub media asset, and the extended text table ETT may be used to characterize play information of the sub media asset.

In some embodiments, the reservation recording instruction may be input through the control device 100; alternatively, the recording reservation instruction may be input by means of a touch operation. For example, the user calls out a setting interface for recording media assets in the display device 200, and then inputs a reservation recording instruction of the target media assets in the setting interface for recording media assets by the control device 100 or a touch operation mode. Alternatively, the recording reservation instruction may be input by voice input. For example, the user may directly speak a voice instruction "please help me reserve recording of the target media" to the display device 200.

S200: and detecting the target name of the target media asset.

After searching the program list, the display apparatus 200 detects the name of the target asset to search the program list for sub-assets similar to the target asset by the name of the target asset. Because the play time of the sub-media assets may be adjusted and changed, the embodiment of the application determines the recording of the media assets by matching the program list and the media asset names, and can improve the limitation of timing recording or real-time recording.

S300: and inquiring the associated media assets in the program list.

After detecting the target name of the target media asset, inquiring similar sub media assets in the program list as associated media assets. Wherein, the associated media asset is a sub-media asset with the similarity of the media asset name and the target name being greater than or equal to a similarity threshold.

In some embodiments, the display device 200 detects a target channel for a target asset when querying the program listing for an associated asset. After detecting the target channel of the target media asset, inquiring the target channel in the program list, and acquiring the sub media assets in the target channel to generate a media asset set to be screened. After the media asset collection to be screened is generated, the display device 200 marks the associated media asset in the media asset collection to be screened.

For example, if the channel of the target asset is DC a, the target channel detected by the display apparatus 200 is DC a. When the display device 200 queries the associated media assets, sub media assets corresponding to the channel DC a in the program category are acquired as the media asset collection to be screened. Namely, the sub-assets included in the media asset collection to be screened are all sub-assets corresponding to the channel DC a. The display device 200 determines sub-assets with similar asset names to the target names in the asset collection to be screened as associated assets.

As shown in fig. 9, in some embodiments, the display device 200 extracts a target text of a target name when marking associated assets in a set of assets to be screened, and traverses the asset names of the set of assets to be screened to obtain a name text of the asset names. And calculating the text similarity of the target text and the name text. If the text similarity is greater than or equal to a similarity threshold, marking the sub-media assets corresponding to the name text as associated media assets; and if the text similarity is smaller than the similarity threshold, deleting the sub-assets corresponding to the name text in the media asset set to be screened. Thus, the sub-assets similar to the target names can be determined from the media asset names in the set to be screened.

Also, in some embodiments, the text similarity may be an edit distance of the target text and the name text, the greater the edit distance, the higher the text similarity; the smaller the edit distance, the lower the text similarity. The Edit Distance (Edit Distance) refers to the minimum number of editing operations required to transfer from one to the other between strings of two texts. Wherein the permitted editing operations include replacing one character with another, inserting one character, or deleting one character.

For example, the channel of the target asset is DC a, and DC a includes sub assets "A1", "A2", "B23", "B24", and "C", and the similarity threshold is edit distance 1. The user inputs a scheduled recording instruction of "A1" to the display device 200, and the display device 200 searches a built-in program list thereof in response to the scheduled recording instruction and inquires all sub-media assets included in the DC a to generate a set to be screened. And acquiring the name text of each media asset name in the set to be screened, and calculating the editing distance between the name text and the target text. And (3) taking the mark with the editing distance less than or equal to 1 as the associated media resource of the target media resource, wherein A1 and A2 are the associated media resources of the target media resource A1.

S400: and creating a recording task according to the play information of the associated media assets.

After inquiring the associated media asset of the target media asset, the display device 200 creates a recording task of the associated media asset according to the play information of the associated media asset in the program list. The recording task comprises playing information of the associated media assets. The display device 200 may record the associated media asset according to the play information in the recording task.

For example, taking a program category as an EPG, the play information includes play time information. The display device 200 determines the associated media asset of the target media asset according to the media asset name included in the event information table in EP G. After the associated media assets are determined, a recording task is created according to the playing information corresponding to the associated media assets in the expansion text table, and the playing time information of the associated media assets is recorded.

S500: recording the associated media assets according to the recording task to generate video data.

After the display device 200 creates the recording task, the associated media asset may be recorded according to the recording task to generate video data of the associated media asset. The sub-media asset information included in the recording task is related to the associated media asset amount determined by the display device 200. When a plurality of sub-media assets are associated with each other, the recording task comprises playing information of the plurality of sub-media assets; when the associated media asset is a sub media asset, the recording task only comprises the playing information of the sub media asset.

The display device 200 may record the associated assets via a built-in video recorder, i.e., in some embodiments, the playback information includes playback time information including a start time point and an end time point. As shown in fig. 10, when the display device 200 records the associated media asset according to the recording task, the playing time information of the associated media asset in the recording task is extracted to determine the starting time point and the ending time point of the associated media asset. When the starting time point is reached, starting a video recorder and recording the associated media assets of the target channel through the video recorder; when the end time point is reached, the video recorder is turned off to generate video data.

For example, the target channel is DC a, the target media asset is "a1", the related media asset queried by the display device 200 is "A1" and "A2", and the recording task includes the playing information of "A1" and "A2". Wherein, the starting time point of A1 is 9:00, and the ending time point is 9:45; the starting time point of A2 is 10:00 and the ending time point is 10:45. The display device 200 records the related media assets A1 and A2 according to the recording task, when the recording task reaches 9:00, the video recorder is started to record DC a, and when the recording task reaches 9:45, the video recorder is closed; when 10:00 is reached, the video recorder is started to record DC a, and when 10:45 is reached, the video recorder is shut down. In this way, the display device 200 can automatically generate video data of the related media files "A1" and "A2" for playback and viewing by the user.

Since the content of the program list may also change in update, in order to improve the accuracy of the associated media recording, in some embodiments, the display device 200 also monitors the update information of the program list, and when the program list is updated, the updated program list is loaded. The program list is updated as the program list with the latest updating time point. After the updated program list is loaded, the playing information of the recording task is updated through the updated program list, so that the accuracy of the playing information in the recording task is ensured.

Alternatively, in some embodiments, the display apparatus 200 may also load an updated program list at a target point in time, and update the play information of the recording task according to the updated program list. That is, the display apparatus 200 can reload the program list once at a fixed point in time, thereby improving the problem of inaccurate recording due to program list variation. For example, in the presence of a recording task, the display device 200 sets to reload the program list once a day to 0:00 and updates the recording task with the newly loaded program list.

S600: and writing the video data into a memory.

After the recording of the related media assets is completed, the display device 200 writes the generated video data into the memory 280 for the user to play back and view. That is, the video data is written into the memory 280 of the display apparatus 200 as a local file of the display apparatus 200; the user can play the local file in the display device 200, so as to realize the playback and viewing of the live program.

However, the number of associated assets may be plural or one, and the plural associated assets have a certain correlation, and are series of assets. For example, the number of the drama episodes is generally a plurality of, and the number of the corresponding sub-media assets is also a plurality of; when the television episode is recorded, a plurality of local files of video data are formed. Therefore, in order to facilitate the display of the video data of the series of media assets, the video data of the same series of media assets should be sorted, and the associated media assets belonging to the same series of media assets should be sorted into the same folder. And the process of organizing the associated media assets needs to distinguish whether the associated media assets are series media assets.

Thus, to simplify the interactive process of display device 200 distinguishing associated assets, in some embodiments, display device 200 also obtains parent program information for the associated assets. Wherein the parent program information includes an event identification code, which is a unique digital ID that is bound to the asset. For example, the "A1" and the "A2" are related media resources of the same series, and the corresponding event identification codes are also the same time identification codes; the A1 and the B1 are related media resources of different series, and respectively correspond to two different event identification codes. And detecting the associated media asset quantity corresponding to the event identification code so as to determine whether the current media asset is a series of media assets or not according to the associated media asset quantity.

After detecting the number of associated assets, the display device 200 determines whether the current associated assets are series assets according to the number of associated assets. If the number of the associated media assets is 1, indicating that the current associated media assets are not series media assets, and setting the file name of the video data as a first file name. The first file name comprises a storage serial number of video data. If the number of the associated media assets is not 1, indicating that the current associated media assets are series media assets, and setting the file name of the video data as a second file name. The second file name comprises an event identification code and a storage serial number of video data. By setting different file names, the series media assets and the non-series media assets can be distinguished on the premise of not changing the file structure of the video data. In this way, the display device 200 can use the same interactive logic for the video data, thereby improving the management efficiency of the video data.

For example, the related assets are taken as series of assets. After the display device 200 records the associated media assets through the recording task, video data of the associated media assets are generated. And establishing the name of a recording folder according to the Event identification code Event ID of the series of media assets and the storage serial number during recording, and storing video data into the folder.

It is understood that the first file name and the second file name are both names of folders storing video data. In the embodiment of the application, in order to unify the interactive logic of the video data, the data files of the video data are kept in the same name and format. In this way, the display device 200 can maintain uniform interaction logic when decoding and playing back video data. When distinguishing whether the video data is a series of media assets, distinguishing is carried out through the first folder name and the second folder name. If the folder name of the folder comprises an event identification code, the current video data can be judged to be series media assets; if the file name of the folder does not include the event identification code, the current video data can be judged not to be the series media assets.

To facilitate management of video data for a series of assets, in some embodiments, display device 200 creates a parent folder based on an event identification code as video data is written to memory 280. Wherein the file name of the parent folder is generated based on the event identification code of the second file name. And inquiring the target video data with the file name being the second file name, and identifying the event identification code of the target video data. And storing the target video data into a target father folder. The file name of the target father folder is the same as the event identification code of the target video data. The video data with the same event identification code are placed in the same father folder, and the video data in the same series can be uniformly classified, so that a user can conveniently inquire and select.

For example, the video data generated by the display device 200 includes "A1", "A2", "B23", "B24" and "C", where "A1" and "A2" are the same series of media, "B23" and "B24" are the same series of media, and "C" is not a series of media. The time identification code corresponding to A1 and A2 is 1222, and the event identification code corresponding to B23 and B24 is 1356. The display device 200 creates a parent folder with file names 1222, 1356, and video data of "A1" and "A2" is stored in the parent folder with file name 1222; video data of "B23" and "B24" are stored in a parent folder with a file name of 1356.

In some embodiments, in response to a playback list presentation instruction for video data, display 260 is controlled to fold and display target video data located in the same parent folder. For example, the "A1" and "A2" are the same series of media assets, the "C" is not a series of media assets, and the video data of "A1" and "A2" are stored in a parent folder with a file name 1222. When the playback list is displayed, the display device 200 folds and displays the video data in the 1222 parent folder as shown in fig. 11. In this way, the user can more intuitively find the video data to be played back in the playback list.

In some embodiments, the playback list further includes a tile tab. When the parallel display tab is in the selected state, the display device 200 masks the event identification code in the second file name and searches for video data according to the storage serial number. And displaying the video data in the playback list in parallel. Wherein the playback list includes a picture preview of the video data.

In some embodiments, a channel code is also included in the second file name. When the display device 200 displays the playback list, the channel code in the second file name may be detected, and video data adjacent to the channel code may be set to be displayed in a neighboring position. For example, the channel number of the channel DC a is 1 and the channel number of the channel DC b is 2 in the display device 200; when the playback list is displayed, setting the video data of DC a and DC b to adjacent positions for display.

Further, in some embodiments, the playback list of display device 200 includes playback option controls for presenting video data. That is, the display device 200 may generate a playback list of video data from the video data stored in the memory 280. The user may generate a playback instruction for the target media asset by performing a selected operation on the playback option control.

In some embodiments, the display device 200 extracts video data of the target asset in the memory 280 in response to a playback instruction for the target asset. And then performs decoding on the video data of the target media asset, and controls the display 260 to display the playing picture of the target media asset.

In some embodiments, the display device 200 also detects the characteristic value of the display device 200 when the video data is written to the memory 280. Wherein the characteristic value comprises identification information, such as a mac address, SN number, etc., for characterizing the display device 200. After detecting the feature value of the display apparatus 200, the display apparatus 200 sets a key according to the feature value, and encrypts the asset data based on an encryption algorithm to form encrypted video data of the target asset. The encrypted video data is written into the memory 280 to protect the asset data of the target asset.

The encryption algorithm is to execute encryption processing on the clear text media asset data to make the media asset data become a section of unreadable code to form encrypted video data. The encrypted video data can only display original plaintext data after the corresponding key is input, that is, the encrypted video data can only be decrypted through the characteristic value of the display device 200, and the encrypted encoded information is converted into the original form of the media asset data.

Accordingly, the display apparatus 200 can decrypt the video data through the feature value. That is, in some embodiments, the display apparatus 200 extracts video data in the memory 280, and performs decryption on the video data by the feature value, and controls the display 260 to display a play screen of the media asset data. Thus, the video data of the memory 280 can only be played in the authorized display device 200, and the video data of the target media asset can be protected.
