And after the kernel is started, loading the Shell and the user application program. The application program is compiled into machine code after being started, and a process is formed.
Referring to fig. 4, in some embodiments, the system is divided into four layers, which are an Application (Applications) layer (abbreviated as "Application layer"), an Application Framework (Application Framework) layer (abbreviated as "Framework layer"), an Android runtime (Android runtime) and system library layer (abbreviated as "system runtime library layer"), and a kernel layer from top to bottom.
In some embodiments, at least one application program runs in the application program layer, and the application programs may be windows (windows) programs carried by an operating system, system setting programs, clock programs or the like; or an application developed by a third party developer. In particular implementations, the application packages in the application layer are not limited to the above examples.
The framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system and obtain the services of the system in execution through the API interface.

The display apparatus 200 may play the media asset on-line through the server 400. Server 400 may provide display device 200 with one or more media asset platforms in which resource content, play links, and other media asset-related data content for a plurality of media asset items may be included. These data may be stored in the server 400, and when the display device 200 needs to play the asset item in the platform, it may request the asset data corresponding to the asset item to be played by sending a play request.
For example, as shown in fig. 5, for the juvenile media asset project platform, the server 400 may transmit media asset information to the display device 200 to provide a juvenile channel interface in the display device 200, where a plurality of media asset projects suitable for watching by the juvenile, such as cartoons, educational videos, etc., may be included in the juvenile channel interface. The user may select a media asset item to be played through the juvenile channel interface, and the display device 200 may transmit a media asset playing request to the server 400 according to the selection of the user. After receiving the media asset playing request, the server 400 extracts the media asset data from the juvenile media asset project platform, and feeds back the media asset data to the display device 200, so that the display device 200 plays the fed back media asset data.
In the process of playing the media asset item by the display device 200, the display device 200 may acquire the media asset data from the server 400 in real time, and continuously form a media asset picture through decoding, rendering and other processes. Moreover, the display device 200 may also monitor the playing process of the asset item in real time, and when the playing process of the asset item is interrupted, the display device 200 may automatically record the playing progress of the asset item to generate a history. The history record can enable the user to directly continue playing according to the recorded playing progress when playing the media asset item again so as to meet the requirement of the user on continuing watching.
The server 400 may further analyze the play history of the display device 200, determine the viewing preference of the user according to the media asset items played by the user in the history, and send the recommended media assets to the display device 200 according to the viewing preference of the user. In order to obtain the viewing preference of the user, the server 400 may set a tag for each asset according to the specific content of the asset, where the tag content may be content capable of reflecting the characteristics of the asset item, such as asset name, asset category, asset author, asset length classification, and the like. The server 400 may determine a viewing preference of the user according to the statistical result of the number of times that the tags appear in the history, and push the media asset items with the same tags to the display device 200 according to the determined viewing preference.
For example, by analyzing and processing the user history record, and determining that the number of media asset items with animation tags in the history record is large, the server 400 may determine that the viewing preference of the user is a sub-supply, and thus may push a recommended media asset item of an animation type to the display device 200.
The recommended asset items sent by the server 400 to the display device 200 may be displayed in a specific user interface, such as a media asset recommendation interface like a home interface of an operating system. As shown in fig. 6, the home interface of the operating system may include a plurality of media asset recommendation positions, and each media asset recommendation position may display a recommended media asset item. The home interface displays the recommended media asset item and simultaneously displays other items, such as a channel option, a mode option, a VIP function option, a link option, a menu option and the like. Thus, there is a limit to the number of asset recommendation bits in the home interface.
Since the number and types of the asset items are large and the viewing preferences of the user are not limited to a single form, the server 400 can also classify the asset items into several broad categories, such as movies, television shows, documentaries, children, education, etc. Therefore, the server 400 may further set a resource channel for each category, and each resource channel may have a plurality of recommendation bits for recommending resource items of the category to which the channel belongs. For example, on the recommendation position under the juvenile channel, the recommended media asset items meeting the juvenile viewing requirements, such as animation films, science and education films and the like similar to the media assets viewed by the user, can be displayed; and a tv show asset item similar to the asset viewed by the user may be displayed in the recommendation position under the movie channel.
After the display device 200 acquires the recommended media asset item, the display device 200 may generate a media asset recommendation interface according to the acquired data and display the media asset recommendation interface. Therefore, the user can select the interested recommended media asset item in the display media asset recommendation interface and play the item. That is, the display apparatus 200 may transmit a play request to the server 400 to request the asset data of the selected recommended asset item after the user inputs a control instruction to select the recommended asset item. The server 400 extracts the media asset data from the media asset platform to form a data stream, and feeds the data stream back to the display device 200 for playing.
In order to enable the user to know more information about the playing process, in some embodiments, the display device 200 may display the asset detail interface first during the playing process of the asset. As shown in fig. 7, in the asset detail interface, various information related to the assets to be played, such as the type, duration, author, introduction of scenario, etc. of the assets may be included. In the media asset detail interface, a plurality of functional options can be included, such as a play option, a collection option, and the like. The user may control the playing process of the display device 200 by clicking on the corresponding option. For example, the user may control the display device 200 to play the target asset by selecting a play option. The user may also control the display apparatus 200 to display a plurality of episode options by selecting an episode option, and select an episode desired to be viewed among the episode options to play. The user may also control the display device 200 to collect or cancel collection of the target asset items by selecting the collection option. After the target asset item is collected, the display device 200 may further display the target asset in a collection interface for the user to select to play.
In addition to the above-mentioned manner of recommending media asset items according to the user history, in some embodiments, the server 400 may also uniformly push recommended media asset items to the display device 200 according to the operation status. For example, for a newly online popular movie and television item, the server 400 may also use the recommendation position in the media asset recommendation interface to display, so that the user can select the recommended media asset item for playing.
The asset items typically have the property of being an adapter model or system version, i.e., the asset items require the display device 200 to meet specific hardware parameters or software parameters to be able to be played. For example, the decoding process and the display process of the asset item of 4K resolution require a large amount of computing power, and thus the display device 200 is required to have a sufficiently strong decoding power and display resolution to be viewed normally. When the computing power of the display device 200 cannot support the playback of the 4K asset item, the user cannot control the display device 200 to complete the playback.
For recommending asset items, since the asset recommendation process is intended to guide a user to view a particular asset item, the recommended asset item is typically an asset item that the user has not viewed. Moreover, the server 400 may establish a communication connection with a plurality of display devices 20 at the same time, so that the server 400 cannot ensure that all display devices 200 support playing of the recommended asset items, so that when a user selects a recommended asset item, a playing process cannot be completed by some display devices 200. As shown in fig. 8, when the display device 200 does not support playing of the recommended asset item, a prompt interface may be presented.
In order to enable all recommended media asset items displayed in the media asset recommendation interface to be played by the display device 200, in some embodiments, the server 400 may further implement accurate pushing of the recommended media asset items by means of offline timing calculation and full real-time calculation. That is, the server 400 may perform permutation and combination according to parameters such as the model, the operating system version, and the application scenario of the connected display device 200, exhaust media asset items suitable for each model, each version, and each scenario, acquire the model, the version, and the scenario of the display device 200 when the display device 200 requests a first page interface, extract recommended media asset items from the permutation and combination exhausted previously, and feed back the recommended media asset items to the display device 200.
However, since there are many specific parameter values of parameters such as models, versions, and scenes of the display device 200, the data size of the permutation and combination process using offline timing calculation is huge, and the data size after combination is generally millions, which severely consumes the computing resources of the server 400. In addition, the online calculation time of the full real-time scheme is long, and a user can see the media asset recommendation interface only after waiting for a long time, so that the user experience is influenced.
Based on this, in some embodiments of the present application, a media asset filtering method is provided, which is used to filter media asset recommended items that do not support the display device 200 to play in time, so as to improve the playing efficiency of the recommended media asset items. The media asset filtering method may be applied to a multimedia system consisting of the display device 200 and the server 400. In order to meet the implementation requirement of the media asset filtering method, the display device 200 and the server 400 are required to have certain hardware configuration requirements. The display device 200 should at least include a display 260, a communicator 220 and a controller 250. The display 260 is used for displaying various user interfaces including a media asset recommendation interface; communicator 220 is configured to establish a communication connection with server 400; the controller 250 is configured to execute the program steps corresponding to the display device 200 side in the media asset filtering method.
Similarly, to satisfy the requirement that the media asset filtering method is implemented, the server 400 at least includes a storage module 410, a communication module 420 and a control module 430. The storage module 410 is used for storing media asset data. The communication module 420 is used to establish a communication connection with the display apparatus 200. The control module 430 is configured to execute the corresponding program steps of the server 400 side in the media asset filtering method, so as to implement the media asset filtering function.
Specifically, as shown in fig. 9 and 10, the media asset filtering method includes the following steps:
the display device 200 displays a media asset recommendation interface for the user to select a recommended media asset item to be played in the media asset recommendation interface. The media asset recommendation interface is one of user interfaces, and can comprise at least one recommendation position for displaying recommended media asset items. The user may control the display device 200 to display the media asset recommendation interface by inputting a control instruction for displaying the media asset recommendation interface. The control instruction for displaying the media asset recommendation interface can be input in various ways. For example, the user may input a power-on command through the control device 100 associated with the display apparatus 200 to control the display apparatus 200 to be powered on. The display device 200 may run a start-up program of the operating system to present a home interface after receiving the power-on instruction. The home page interface can comprise a plurality of recommendation bits, namely a media asset recommendation interface.
When the display device 200 displays the home interface, the user may also control the movement of the focus cursor through the direction keys on the control device 100, and when the focus cursor selects different channel options in sequence, the user may control the tabs in the home interface to switch, and then the tab interface of each channel may also include a recommendation bit, that is, each channel tab interface is also a media asset recommendation interface.
In addition, a recommendation bit may also be included in some user interfaces for presenting recommended asset items. For example, in the asset detail interface of asset a, a recommendation bit may also be included for presenting asset items similar to asset a. A recommendation bit can also be included in the pause screen of the play interface of the asset a for displaying the asset items similar to the asset a. The user inputs a control instruction for displaying the media asset recommendation interface when the user triggers the display device 200 to display the interfaces through a specific interactive action.
After receiving the control instruction for displaying the media asset recommendation interface, the display device 200 may acquire, in response to the control instruction, recommended media asset arrangement data for rendering the media asset recommendation interface from the server 400. I.e., sends a media asset recommendation interface display request to server 400.
Obviously, since the media asset recommendation interface may be represented in various forms in the display device 200, after receiving a control instruction for displaying the media asset recommendation interface, the display device 200 generates a display request according to an input manner of the control instruction. For example, when the user controls to switch the channel to the "kids" channel, the display device 200 needs to extract a large category of recommended assets, i.e., the "kids" category, according to the content in the displayed interface after switching. And then generates a display request according to the determined large class so as to request the children class recommendation media asset item from the server 400.
As shown in fig. 11, after acquiring the recommended-media-asset interface display request input by the display device 200, the server 400 may acquire recommended-media-asset arrangement data in response to the display request. The recommended media asset arrangement data comprises a plurality of recommended media asset items, and the number of the recommended media asset items contained in the recommended media asset arrangement data is larger than or equal to the number of recommendation bits in a media asset recommendation interface to be displayed. For example, when the media asset recommendation interface includes 5 recommendation bits, the server 400 may extract 5 recommendation media asset items that are issued by the operator in a unified manner or the recommendation media asset item with the highest matching degree calculated through the history record, generate recommendation media asset arrangement data, and feed back the recommendation media asset arrangement data to the display device 200.
After receiving the recommended media asset arrangement data, the display device 200 generates a media asset recommendation interface according to the media asset arrangement data, and adds the recommended media asset items in the recommended media asset arrangement data to the recommendation position to form a media asset recommendation interface.
In some embodiments, in the display request input by the display device 200 into the server 400, the device parameters of the display device 200 are further required to be included, and the device parameters may specifically include parameter contents such as model parameters, version parameters, and scene parameters. For example, when the user opens the media asset playing APP on the display device 200, the media asset playing APP may request the top page data from the system main page interface of the server 400, that is, send a display request, and when sending the display request, the version parameter and the model parameter of the user may be carried. The system side of the server 400 matches the layout data of the corresponding home interface according to the parameters included in the display request of the display device 200.
Since the model parameters and version parameters of multiple display devices 200 are coincident, that is, different display devices 200 may have the same model parameters and version parameters, in some embodiments, the layout data provided by the server 400 to the display devices 200 may also be shared by multiple models and versions, that is, display devices 200 of the same model and version may share one set of layout data. After obtaining the display request of the display device 200, the server 400 may directly obtain a set of layout data conforming to the model and version of the display device 200 according to the device parameters carried in the display request, and feed back the set of layout data to the display device 200, so as to reduce the amount of data calculation.
In order to support the media asset filtering method provided in this embodiment, the server 400 may also maintain an online state parameter in the server 400 while sending the recommended media asset arrangement data to the display device 200, where the online state parameter is used to record a compatible state of the recommended media asset to the hardware configuration of the display device 200. The online status parameter may store a remote dictionary service redis status value in the server 400. That is, when the model, version parameter of the display device 200 supports the recommended-asset playback, the redis status value may be set to 1, and when the model, version parameter of the display device 200 does not support the recommended-asset playback, the redis status value may be set to 0. For example, when the display device 200 requests that the media asset recommendation interface includes media asset a, and the online state of the media asset a to the display device 200 is online, the redis state value may be set to 1. When the display device 200 of the same model and version selects to play the media asset a through the media asset recommendation interface, the media asset a can be directly played, so that the pushing probability of invalid recommended media assets is reduced.
It should be noted that, in the foregoing embodiment, the server 400 stores the redis state value, which may represent a composite online state of the recommended media asset item corresponding to the device parameter of the display device 200. In the storage process, the online state may maintain a specific storage structure, that is, the server 400 may store based on a hash data structure of redis, where a key value is a model parameter $ featurecode $ contentId, a value-key value is a version parameter versioning, a value of 0 indicates that the online state of the recommended media asset to the current display device 200 is offline, and a value of 1 indicates that the online state of the recommended media asset item to the current display device 200 is online.
The server 400 may set an online state for the device parameter for each recommended media asset item in the recommended media asset arrangement data while transmitting the recommended media asset arrangement data to the display device 200. That is, in some embodiments, the server 400 may query the remote dictionary service according to the device parameters to obtain the online status of the recommended media asset items on the device parameters. That is, for the display device 200 for which the online state corresponding to the current model and version parameter has been set, the server 400 may directly acquire the online state by querying the state value key in the redis.
After obtaining the online state, the server 400 may further screen the recommended media asset items sent to the display device 200 according to the online state, that is, by traversing a redis state value corresponding to each recommended media asset item and deleting the recommended media asset items with a redis state value of 0 in the recommended media asset arrangement data, the recommended media asset items pushed to the display device 200 by the server 400 may be preliminarily filtered according to the set online state, so as to remove the recommended media asset items that are determined not to support playing.
For the recommended media asset items for which the online states are not set, the server 400 may also have the online states for the current model and version parameters by adding default values. That is, in some embodiments, if the online state of the recommended media asset item to the device parameter is not queried in the remote dictionary service, the online state is set for the recommended media asset item, and the default redis state value of the recommended media asset item is 1.
Through the setting manner of the online state corresponding to the redis state value, the server 400 can enable all recommended media asset items in the recommended media asset arrangement data sent to the display device 200 to be set in the online state. And, the server 400 may store the online status of the recommended media asset item on the current device parameter. When the display device 200 with the same model and version parameters requests to display the media asset recommendation screen, the recommended media asset item with the redis state value of 1 can be acquired according to the set state.
After the above setting, the recommended media asset items pushed to the display device 200 by the server 400 may correspondingly record an online state, which is used as a basis for filtering the recommended media asset items when the display device 200 requests to display a media asset recommendation interface of the same model and version subsequently. The online state may be updated according to the play situation when the display device 200 of different models and different versions requests to play the corresponding recommended media asset item. For example, when the display device 200 of one model and version requests to play the asset a and can play the asset smoothly, the online state of the asset a to the current model and version parameters may be updated to be online, that is, the redis state value is modified to be 1. Otherwise, the redis state value is modified to 0.
In order to implement the above functions, after the display device 200 displays the media asset recommendation interface, the display device may acquire a control instruction for playing the recommended media asset item, which is input by the user based on the media asset recommendation interface. For example, if the recommended media asset a is included in the media asset recommendation interface displayed by the display device 200, the user may select the media asset a to play based on the currently displayed media asset recommendation interface, that is, input a control instruction for playing the recommended media asset item.
According to the difference of the interactive modes supported by the display device 200, the user can input the control instruction for playing the recommended media asset item through different interactive modes. For example, the control device 100 may control the focus cursor to move to select the recommended asset a in the asset recommendation interface, may select the recommended asset a through touch interaction, and may input voice content such as "play asset a" through a voice interaction manner to control the display device 200 to play the recommended asset a.
It should be noted that the control instruction for playing the recommended asset item may also be input based on other interfaces besides the asset recommendation interface. For example, in a user interface where the recommended media asset item is not displayed, the display device 200 may also be controlled to play the specified media asset item through methods such as voice interaction and gesture touch operation, and for the playing process of such media asset items, media asset filtering may also be performed according to the manner provided in this embodiment.
After acquiring the control instruction for playing the recommended media asset item, the display device 200 may extract the recommended media asset item specified by the control instruction and detect the current device parameter in response to the control instruction. For example, when the user selects the recommended asset a to play, the display device 200 may extract the designated recommended asset item as asset a from the control instruction. Meanwhile, the display device 200 may also obtain its own device parameters by reading the system parameters. The device parameters may include model parameters and operating system version parameters, for example, by detecting the device parameters, the model parameters of the current display device 200 may be determined to be hxx-65E 5G, while by detecting the operating system version, the version parameters may be obtained to be jxvi UI 2.0.
After extracting the recommended asset items and the current device parameters, the display device 200 may generate a play request according to the extracted content. I.e. the play request comprises recommended media asset items and device parameters. The display device 200 then transmits the generated play request to the server 400, so that the server 400 feeds back media asset data according to the play request and updates the online state.
That is, the server 400 may first query the asset data of the recommended asset items in response to the play request. When querying the media asset data corresponding to the recommended media asset item, the server 400 may perform media asset data retrieval according to the identification information of the recommended media asset item to be played, such as a media asset ID, a media asset name, and the like, so as to determine the media asset data corresponding to the recommended media asset item in the storage module 410 of the server 400.
For example, after the server 400 receives the play request, the asset ID of the recommended asset item may be extracted from the play request: 11017041395, inquiring the media data in the server 400 according to the media asset ID, and when the server 400 stores the media asset data with ID 11017041395, that is, the media asset data with media asset content of "× world season 2", the server 400 may further determine based on the media asset data to determine whether the current display device 200 supports playing of the media asset data.
Obviously, when the server 400 queries the asset data of the recommended asset item, it may or may not query the appropriate asset data, and when the asset data is queried, the server 400 may determine whether the current display device 200 supports playing of the asset data. When the media asset data is not queried, it indicates that the currently recommended media asset item may not be provided due to offline of the media asset or other failures, so the server 400 may send a prompt message to the display device 200 to prompt the user that the current play cannot be completed.
After querying the media asset data of the recommended media asset item, the server 400 may detect a support state of the device parameter for playing the media asset data. That is, the server 400 may determine the support state of the device parameter for playing the media asset data according to the data specification of the type, format, resolution, data volume, and the like of the media asset data. The server 400 may determine the current hardware configuration of the display device 200 according to the model version in the device parameters, that is, determine whether the current display device 200 has sufficient arithmetic processing capability. Meanwhile, the server 400 may determine whether the current display apparatus 200 is configured with a control program corresponding to a specific play function according to the version parameter, so as to determine whether the current display apparatus 200 can perform a decoding operation on a specific file format.
For example, for the low-end display device 200, the model of the controller 250 itself is located at the low end, the corresponding dominant frequency is lower, the number of cores is also smaller, and generally there is no separate image processing module, so that it cannot meet the requirement of playing the high-resolution media asset data. Therefore, when the device parameter of the display device 200 is determined to be the low-end device parameter, the playback cannot be completed for the recommended asset item that provides only 4K, 8K resolutions, that is, the support state of the device parameter for the playback asset data is determined to be "unsupported". Similarly, for the higher-end display device 200, when the os version is lower, the playing of the specific media asset data cannot be supported. For example, if the decoding function for the asset data in the ". rmvb" format is a function added when the operating system in the jxui 2.1 version is updated, when the version parameter acquired by the server 400 is jxui 2.0, since the display device 200 is not configured with a system for decoding the ". rmvb" format, it may also be determined that the support state of the device parameter for playing the asset data is "unsupported".
After detecting the support state of the device parameter for playing the media asset data, the server 400 may update the online state of the recommended media asset item for the device parameter according to the support state. Namely, if the device parameter supports the playing of the media asset data, setting a redis state value corresponding to the recommended media asset item to be 1; and if the equipment parameters do not support the playing of the media asset data, setting the redis state value corresponding to the recommended media asset item to be 0. After updating the online state of the recommended media asset item on the device parameter, the server 400 may further store the updated online state, so that when the subsequent display device 200 having the same device parameter plays the recommended media asset item again, the online state may be directly determined according to the stored redis state value, and filtering of the recommended media asset item that does not support playing by the current display device 200 is implemented.
For example, when the user 1 requests to play the asset a that only provides 4K or more resolution film sources through the low-end display device 200, the server 400 may determine that the current display device 200 does not support the play of the asset a according to the device parameters of the display device 200 and the play requirement of the asset a. Therefore, the online information of the asset a to the model of the display device 200 can be updated from the redis state value of the default value being 1 to the redis state value being 0, and stored.
After the online state is updated, the server 400 may record a state that the current low-end display device 200 does not support playing of the media asset a, so that the user 2 uses the display device 200 with the same model and version parameters to request display of the media asset recommendation interface again, the media asset a may be filtered out, the media asset a is no longer recommended to the display device 200 with the same model and version, waste of recommendation bits is alleviated, and invalid operation times of the user are reduced.
It can be seen that, in the above embodiment, by controlling the write-in timing of the online state redis state value, the online states of multiple recommended media asset items on the parameters of each device can be recorded in the server 400 according to the process of requesting to play the media asset items by each model and version display device 200, so that less resources are not required to be utilized, and the best experience is presented to the user.
For example, in a multimedia system, the number of composite assets is about 10 ten thousand, the number of models is thousands, the number of versions is hundreds, and there may be hundreds of millions of keys in redis according to the number, so that all assets cannot be enumerated in advance in the case of less computing resources. If the result of the composite media asset is queried when the query is triggered by reading, namely the query cannot be performed from the redis, the request delay is increased by about 500ms, and the user experience requirement cannot be met. Therefore, the embodiment can trigger writing for the detail page of the design structure of the cache data, that is, only when the user really triggers the detail page of the media asset and goes offline, the online state of the media asset can be written in the redis.
The triggering mode can greatly reduce the number of keys in the redis. Firstly, although there are 10 ten thousand assets, the popular assets have very obvious head effect and can be basically controlled within 2000; secondly, most of the assets are universal in requirements on the models and versions, and the problem of model version filtering can be met only if the assets with special attributes are similar to 4K, 3D and the like, offline state writing of the assets is triggered, the proportion is about 5%, and therefore keys needing to be stored in redis are reduced to about 10 ten thousands, and normal support can be achieved by using a redis cluster.
In addition, the models used by the users also have a great aggregation effect, and most of the users are concentrated in about 100 main stream models, so that the actual key in the redis is basically controlled within 5 ten thousand, but the user experience and the operation effect are greatly improved. Since most users cannot see the recommended content of the offline, especially the head position, except for individual users, the influence on the operation effect is particularly great.
It should be noted that, in order to reduce the excessive occupation of the storage space of the server 400 by the online state record and make the online state recorded by the server 400 time-efficient, in some embodiments, the server 400 may further set an expiration time for the online state according to the actual operation rhythm, and when the online state setting time exceeds the expiration time, the server 400 may delete the record or reset the online state. For example, an on-line status may set an expiration time of 1 day in redis.
In some embodiments, if the device parameter supports playing of the asset data, the asset data is transmitted to the display device 200 so that the display device 200 can normally play the recommended asset item. And if the device parameters do not support the play of the media asset data, sending an offline prompt to the display device 200. The offline prompt may be in the form of a push message, that is, the server 400 may cause the display device 200 to display the offline prompt message after receiving the offline prompt in the form of a push message. For example, a prompt message "the current device does not support playing the movie, please select other movies" is displayed in the form of a pop window. The offline prompt may also be in the form of a control command, that is, the server 400 may trigger the display device 200 to perform user interface switching, so that the display device 200 is switched from the current display interface to the offline prompt interface. In the prompt interface, prompt words such as "the content is offline, you can select other content to view" can be displayed.
In some embodiments, after the server 400 obtains the media asset data corresponding to the recommended media asset item, the media asset data may be sent to the display device 200, and whether the playing of the media asset data is supported is determined by the display device 200, and when an abnormal condition that the playing cannot be completed, such as decoding of the media asset data, abnormal display, serious playing jam, and the like, occurs in the display device 200, it is determined that the current display device 200 does not support playing of the media asset data. At this time, the display apparatus 200 may feed back error information to the server 400, so that the server 400 may update the online status of the recommended media asset item on the apparatus parameter according to the error information.
For example, when the display device 200 that does not support 3D video playing requests playing of the 3D film source media asset B, the server 400 may first query the online information of the model of the display device 200 from the media asset B, and if the online information of the media asset B is the default value redis 1, at this time, the server 400 may send media asset data to the display device 200, and after receiving the media asset data, the display device 200 decodes and plays the media asset data according to the currently supported playing capability. Obviously, since the current display device 200 does not support 3D video playing, the decoding operation cannot be completed during playing, and at this time, the display device 200 may feed back error information to the server 400 to indicate that the current playing operation cannot be completed. After receiving the error information fed back by the display device 200, the server 400 stops sending the media asset data to the display device 200, and updates the online state of the media asset B on the current device parameter of the display device 200 from a default value redis of 1 to a value redis of 0.
In some embodiments, when the display device 200 inputs a play request based on the media asset recommendation interface, the server 400 may further re-issue the media asset arrangement data to the display device 200 when it is determined that the current device parameter does not support playing of the recommended media asset item, so as to clear the invalid recommended media asset item in the media asset recommendation interface. That is, after updating the online state of the recommended media asset item to the device parameter, the server 400 may modify the recommended media asset arrangement data of the media asset recommendation interface according to the updated online state, and then feed back the modified recommended media asset arrangement data to the display device 200, so that the display device 200 refreshes the media asset recommendation interface.
For example, as shown in fig. 12, when the media asset recommendation interface requested to be displayed by the display device 200 includes 5 recommendation bits and respectively displays media asset a, media asset B, media asset C, media asset D, and media asset E, the user 1 controls the display device 200 to request to play media asset C, and based on the play request, the server 400 determines that the current display device 200 does not support playing media asset C, and at this time, the online state of the media asset C may be modified according to the support state. And, C is deleted in the raw asset layout data. Meanwhile, media asset F with a higher recommendation degree is obtained, new recommended media asset arrangement data is formed by the media asset F, the media asset A, the media asset B, the media asset D and the media asset E and is sent to the display device 200, so that the display device 200 refreshes a media asset recommendation interface according to the new recommended media asset arrangement data, that is, as shown in fig. 13, the media asset A, the media asset B, the media asset D, the media asset E and the media asset F are displayed on 5 recommendation positions in the refreshed media asset recommendation interface for a user to select to play.
In addition, after the display device 200 is triggered to refresh the media asset recommendation interface, the server 400 further stores the modified recommended media asset arrangement data by using the device parameter as an index. Namely, a set of new media asset recommendation item combination is formed to replace the originally recommended media asset arrangement data used for the current model and version parameters. Therefore, when the display device 200 of the same model and version requests to display the media asset recommendation interface, new recommended media asset arrangement data can be fed back to the display device 200, so that the display device 200 can directly form the media asset recommendation interface by adopting the new recommended media asset arrangement data.
In some embodiments, the online state stored in the server 400 further supports active adjustment, that is, as shown in fig. 14, the server 400 may obtain an adjustment instruction input by an operator for the recommended media asset item, update the online state of the recommended media asset item on the device parameter in response to the adjustment instruction, and then store the online state of the updated recommended media asset item on the device parameter.
For example, during caching, the online state of the asset item changes, for example, the asset item that is originally in the offline state under the corresponding model version generates a state value of the offline state in redis, and caches the data. However, due to the adjustment of the special content, the media assets under the corresponding model version become an online state, and the data cached in the redis and the real state deviate at this time. For this situation, the server 400 may monitor the arrangement of the asset items, and if the content under the asset is changed, the deletion of all key values of the asset in the redis is triggered, and a new online state is given, so as to prevent the content from being not delivered to the display device 200 in time.
Based on the above media asset filtering method, as shown in fig. 15, in some embodiments of the present application, a server 400 is further provided, including: a storage module 410, a communication module 420, and a control module 430.

detecting the support state of the equipment parameters to the playing media asset data;
and updating the online state of the recommended media asset item on the equipment parameters according to the support state, wherein the online state is a remote dictionary service redis state value stored in the storage module.
In cooperation with the server 400, as shown in fig. 16, some embodiments of the present application further provide a display device 200, including: a display 260, a communicator 220, and a controller 250. Wherein the display 260 is configured to display a user interface, the user interface including a media asset recommendation interface; the communicator 220 is configured to establish a communication connection relationship with the server 400; the controller is configured to perform the following program steps:

generating a play request, wherein the play request comprises recommended media asset items and equipment parameters;
sending a playing request to a server so that the server inquires media asset data of the recommended media asset item according to the playing request, detects the support state of the equipment parameters for playing the media asset data, and updates the online state of the recommended media asset item for the equipment parameters according to the support state, wherein the online state is a remote dictionary service redis state value stored in a storage module.
As can be seen from the above technical solutions, the server 400 and the display device 200 provided in the above embodiments may query the media asset data of a recommended media asset item when the display device 200 of a device parameter requests a media asset recommendation interface and plays the recommended media asset item in the media asset recommendation interface, and detect a support condition of the device parameter on playing the media asset data, thereby updating an online state of the recommended media asset item on the device parameter according to the support condition. The server 400 can record and maintain the compatibility between the recommended media asset items and the equipment parameters in real time, so that invalid recommended media asset items in the recommended media asset arrangement data are directly filtered according to the online state when other display equipment 200 with the same equipment parameters request a media asset recommendation interface again, the problem that the invalid recommended media asset items occupy recommendation positions is solved, and user experience is improved.
