Multimedia resources, referred to as media assets, include video, audio, images, etc. that can be played at the user terminal. A multimedia asset may be referred to as a media asset item. The media asset platform may provide a plurality of media asset items for the user terminal. For example, the media resource platform can be maintained through an operation server of a display device such as a smart television and the like, and displayed through a media resource interface on the display device. The user can select any media item in the media interface for previewing, playing and collecting through interactive operation.
For different users, the media resource platform can recommend partial media resource items for the users to watch according to the watching histories of the users and the identity information of the users. For example, a media asset recommendation site may be provided in a partial area of the media asset interface, where the media asset types in the media asset recommendation site are types that meet the interests of the user, and these media assets may be referred to as recommended media assets. As can be seen, recommended assets are typically assets that the user has not viewed.
Because the media assets have the attribute of adapting to the model or system version, part of the media assets cannot be played on the display equipment of the part of the model or system version. For example, when the resolution of the frames provided by the media asset is 4k level and the display device does not support the 4k playing function, the display device cannot complete playing of the media asset. In addition, because the recommended position media assets are generally formulated uniformly by the media asset platform, if the display equipment does not support the playing of the recommended position media assets, when the user selects to play the recommended position media assets, no content is visible, the recommended position is wasted and the user experience is reduced.

The display device 200 may play the asset online through the server 400. Server 400 may provide display device 200 with one or more media asset platforms in which the resource content, play links, and other data content related to the media asset may be included for a plurality of media asset items. These data may be stored in the server 400, and when the display device 200 needs to play the media items in the platform, the media data corresponding to the media items to be played may be requested by sending a play request.
For example, as shown in fig. 5, for a juvenile media item platform, the server 400 may send media information to the display device 200 to provide a juvenile channel interface in the display device 200, where a plurality of media items suitable for viewing by a juvenile, such as animation, educational video, etc., may be included. The user may select a media item to be played through the juvenile channel interface, and the display apparatus 200 may transmit a media play request to the server 400 according to the user's selection. After receiving the media data playing request, the server 400 extracts media data from the child media data item platform and feeds back the media data to the display device 200, so that the display device 200 plays the fed back media data.
The display apparatus 200 may acquire the media asset data from the server 400 in real time during the process of playing the media asset item, and continuously form the media asset screen through decoding, rendering, etc. And, the display device 200 may also monitor the playing process of the media asset item in real time, and when the playing process of the media asset item is interrupted, the display device 200 may automatically record the playing progress of the media 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 item again so as to meet the requirement of the user for continuing to watch.
The server 400 may also analyze the play history of the display device 200, and determine the viewing preferences of the user according to the media asset items played by the user in the history, so as to send recommended media assets to the display device 200 according to the viewing preferences of the user. In order to obtain the viewing preference of the user, the server 400 may set a tag according to the specific content of the media asset, and the tag content may be content capable of reflecting the characteristics of the media asset item, such as a media asset name, a media asset category, a media asset author, and a media asset length category. The server 400 may determine user viewing preferences based on statistics of how many times these tags appear in the history, and push media items with the same tags to the display device 200 based on the determined viewing preferences.
For example, by analyzing the user history, determining that the number of media items with movie tags in the history is high, the server 400 may determine that the user's viewing preferences are sub-feeds, and thus may push movie-type recommended media items to the display device 200.
Recommended media items sent by the server 400 to the display device 200 may be displayed in a particular user interface, such as a home interface of an operating system or the like. As shown in FIG. 6, the home interface of the operating system may include a plurality of media recommendation locations, each of which may display a recommended media item. Because the home interface displays the recommended media items, other items, such as channel options, mode options, VIP function options, link options, menu options, and the like, are also required to be displayed. Therefore, the number of media recommendation bits in the home interface is limited.
Because the number and types of media items are numerous, and the viewing preferences of the user are not limited to a single form, the server 400 may also categorize media items into several large categories, such as movies, television shows, documentaries, children, education, and the like. Therefore, the server 400 may also set a media resource channel separately for each category, and each media resource channel may be provided with a plurality of recommendation bits for recommending media resource items of a category to which the channel belongs. For example, on the recommended position under the juvenile channel, recommended media items meeting the juvenile movie requirement, such as cartoon, scientific education sheets and the like, which are similar to the media watched by the user, can be displayed; and on the recommended position under the movie channel, television movie asset items similar to the ones watched by the user can be displayed.
After the display apparatus 200 acquires the recommended media item, the display apparatus 200 may generate a media recommendation interface according to the acquired data and display it. Thus, the user can select and play the recommended media items of interest in the displayed media recommendation interface. That is, the display apparatus 200 may transmit a play request to the server 400 to request media asset data of the selected recommended media asset item after the control instruction for selecting the recommended media asset item is input by the user. The server 400 then extracts the media data from the media platform, and forms a data stream to be fed back to the display device 200 for playing.
To enable the user to know more about the playback process, in some embodiments, the display device 200 may first display the media asset detail interface during playback of the media asset. As shown in fig. 7, in the media asset detail interface, various information related to the media asset to be played, such as the type of the media asset, duration, author, scenario introduction, etc., may be included. In the media asset detail interface, a plurality of function options such as play options, selection options, collection options and the like can be further included. The user can control the play 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 media asset by selecting the play option. The user may also control the display device 200 to display a plurality of episode options by selecting an episode option, and select an episode to be watched among the episode options for play. The user may also control the display device 200 to collect or cancel the collection of the target media asset items by selecting the collection option. When the target media asset item is collected, the display device 200 may also display the target media asset in the collection interface for the user to select to play.
In addition to the above manner of recommending media items according to the user history, in some embodiments, the server 400 may uniformly push recommended media items to the display device 200 according to the operation status. For example, for a newly online movie and television item, the server 400 may also use the recommendation site in the media recommendation interface to display, so that the user can conveniently select the recommended media item for playing.
The media asset item typically has the property of adapting to the model or system version, i.e. the media asset item requires that the display device 200 meet specific hardware parameters or software parameters in order to be playable. For example, the 4K resolution media item decoding process and the display process require a large amount of computing power, and thus the display device 200 needs to have a sufficiently powerful decoding capability and display resolution to be normally viewed. When the computing power of the display device 200 cannot support the playing of the 4K media items, the user cannot control the display device 200 to complete the playing.
For recommended media items, because the media recommendation process is intended to guide the user to view a particular media item, recommended media items are typically media items that the user has not viewed. Also, the server 400 may establish communication connection with a plurality of display apparatuses 20 at the same time, so that the server 400 cannot ensure that all of the display apparatuses 200 support playing recommended media items, so that a portion of the display apparatuses 200 cannot complete the playing process when the user selects the recommended media items. As shown in fig. 8, a prompt interface may be presented when the display device 200 does not support playing recommended media items.
In order to enable the recommended media items displayed in the media 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 items in an offline timing calculation manner and a completely real-time calculation manner. That is, the server 400 may arrange and combine parameters such as the model, the operating system version, and the application scenario of the connected display device 200, exhaust the media items applicable to 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 the home page interface, extract the recommended media items from the previous exhaustive arrangement and combination, and feed back the recommended media items to the display device 200.
However, since the number of specific parameter values of parameters such as model, version and scene of the display device 200 is large, the amount of data in the offline timing calculation permutation and combination process is huge, and the amount of data after combination is usually 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 the user can see the media recommendation interface after waiting for a long time, so that the user experience is affected.
Based on this, in some embodiments of the present application, a media asset filtering method is provided, which is used to timely filter media asset recommended items that do not support the playing of the display device 200, 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 composed of the display device 200 and the server 400. In order to meet the implementation of the media filtering method, both the display device 200 and the server 400 are required to have certain hardware configuration requirements. Wherein the display device 200 should include at least 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; the communicator 220 is configured to establish a communication connection with the server 400; the controller 250 is configured to execute the program steps corresponding to the display device 200 side in the media filtering method.
Similarly, to implement the media filtering method, the server 400 should at least include a storage module 410, a communication module 420, and a control module 430. Wherein, the storage module 410 is used for storing media data. The communication module 420 is used to establish a communication connection with the display device 200. The control module 430 is configured to execute the corresponding program steps on the server 400 side in the media filtering method to implement the media filtering function.
Specifically, as shown in fig. 9 and 10, the media filtering method includes the following steps:
the display device 200 displays a media asset recommendation interface for the user to select recommended media asset items to be played in the media asset recommendation interface. The media asset recommendation interface is one of the 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 instructions for presenting the media asset recommendation interface may be entered in a variety of ways. For example, a user may input a power-on command through the control device 100 matched with the display device 200 to control the display device 200 to start. The display device 200 may run a startup procedure of the operating system to present a home interface after receiving the startup command. The home page interface can comprise a plurality of recommendation positions, namely a media resource recommendation interface.
When the display device 200 displays the home page interface, the user can control the focus cursor to move through the directional key on the control device 100, and when the focus cursor sequentially selects different channel options, the user can control the tabs in the home page interface to switch, and then the tab interface of each channel can also include a recommendation position, that is, each channel tab interface is also a media resource recommendation interface.
In addition, recommendation bits may also be included in some user interfaces for presenting recommended media asset items. For example, a recommendation site may also be included in the media details interface of media asset a for presenting media asset items similar to media asset a. The pause screen of the playing interface of the media asset A can also comprise a recommendation position for displaying media asset items similar to the media asset A. The user inputs a control instruction for displaying the media recommendation interface when the display device 200 is triggered to display the interfaces through a specific interaction.
The display apparatus 200, upon receiving a control instruction for displaying the media asset recommendation interface, may acquire recommended media asset arrangement data for rendering the media asset recommendation interface from the server 400 in response to the control instruction. I.e., sending a media asset recommendation interface display request to the server 400.
Obviously, since the media asset recommendation interface may be represented in various forms in the display apparatus 200, the display apparatus 200 generates a display request according to an input manner of a control instruction after receiving the control instruction for displaying the media asset recommendation interface. For example, when the user controls to switch channels to "juvenile" channels, the display apparatus 200 needs to extract a large category of recommended media assets, i.e., a "juvenile" category, from the contents in the displayed interface after the switch. And then generates a display request according to the determined major category to request the child category recommended media asset items 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 resource arrangement data comprises a plurality of recommended media resource items, and the number of the recommended media resource items contained in the recommended media resource arrangement data is larger than or equal to the number of recommendation positions in a media resource recommendation interface to be displayed. For example, when the media asset recommendation interface includes 5 recommendation bits, the server 400 may extract 5 recommended media asset items from a plurality of recommended media asset items uniformly issued by the operation end or the recommended media asset item with the highest matching degree calculated through the history record, generate recommended media asset arrangement data, and feed back the recommended media asset arrangement data to the display device 200.
The display device 200 generates a media asset recommendation interface according to the media asset arrangement data after receiving the recommended media asset arrangement data, and adds recommended media asset items in the recommended media asset arrangement data to the recommendation site to form the media asset recommendation interface.
In some embodiments, in the display request input by the display device 200 to the server 400, a device parameter of the display device 200 is further required to be included, where the device parameter may specifically include parameter content such as a model parameter, a version parameter, a scene parameter, and the like. For example, when the user opens the media asset play APP on the display device 200, the media asset play APP may request the first page data from the system end mainPage interface of the server 400, that is, send a display request, and when sending the display request, carry the version parameter version code and the model parameter featurecode of the user. The system side of the server 400 matches the layout data of the corresponding home page interface according to the parameters included in the display request of the display device 200.
Since the model parameters and the version parameters of the plurality of display devices 200 have coincidence, 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 a plurality of models and versions, that is, the display devices 200 of the same model and version share a 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 according to the model and version of the display device 200 according to the device parameters carried in the display request, and feed back the data to the display device 200, so as to reduce the data calculation amount.
In order to support the media asset filtering method provided in this embodiment, the server 400 may also maintain an uplink state parameter in the server 400 while sending the recommended media asset arrangement data to the display device 200, so as to record the compatibility state of the recommended media asset to the hardware configuration of the display device 200. The upload state parameter may store a remote dictionary service redis state value in the server 400. That is, when the model, version parameters of the display apparatus 200 support recommended media playback, the redis status value may be set to 1, and when the model, version parameters of the display apparatus 200 do not support recommended media playback, the redis status value may be set to 0. For example, when the display apparatus 200 requests that the media asset a is included in the media asset recommendation interface and the online status of the media asset a to the display apparatus 200 is online, the redis status 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, and the pushing probability of the invalid recommended media asset is reduced.
It should be noted that, in the above embodiment, the server 400 stores the redis status value, which may represent a composite online status corresponding to the recommended media asset item and 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 the hash data structure of redis, where the key value is model parameter $ featurecode $ contentId, the value-key is version parameter version code, the value of 0 indicates that the recommended media asset is offline to the online state of the current display device 200, and the value of 1 indicates that the recommended media asset item is online to the online state of the current display device 200.
The server 400 may set a status of up to the device parameters for each recommended media item in the recommended media asset arrangement data while sending 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 based on the device parameters to obtain a status of the recommended media items on the device parameters. That is, the server 400 may directly acquire the online status by querying the status value key in redis for the display device 200 that has been set with the online status corresponding to the current model and version parameters.
After the status of the upload is obtained, the server 400 may further filter the recommended media items sent to the display device 200 according to the status of the upload, that is, by traversing the redis status value corresponding to each recommended media item, and deleting the recommended media item with the redis status value of 0 in the recommended media layout data, so that the recommended media items pushed to the display device 200 by the server 400 may be initially filtered according to the set status of the upload, to remove the recommended media items determined to not support playing.
For recommended media items for which the online status is not set, the server 400 may also make the recommended media items have the online status for the current model and version parameters by adding a default value. That is, in some embodiments, if the online status of the recommended media item to the device parameter is not queried in the remote dictionary service, an online status is set for the recommended media item, and a default redis status value of the recommended media item is 1.
By the above setting manner of the redis status value corresponding to the online status, the server 400 may set the online status for the recommended media items in the recommended media layout data sent to the display device 200. And, the server 400 may store an up status of recommended media asset items for current device parameters. So that the display device 200 of the same model and version parameters can acquire the recommended media item with the redis status value of 1 according to the setting status when requesting to display the media recommendation screen.
After the setting, the recommended media items pushed to the display device 200 by the server 400 can be correspondingly recorded with an uplink state, and the uplink state can be used as the basis for filtering the recommended media items when the follow-up media recommendation interface is requested to be displayed by the display device 200 of the same model and version. The online status may be updated according to the playing condition when the different models and different versions of the display device 200 request to play the corresponding recommended media items. For example, when the display device 200 of a model or version requests to play the media asset a and can play the media asset a smoothly, the online status of the media asset a for the current model or version parameter may be updated to be online, i.e. the redis status value is modified to be 1. Otherwise, the redis status value is modified to 0.
In order to achieve the above-described function, the display apparatus 200 may acquire a control instruction for playing a recommended media item, which is input by a user based on the media asset recommendation interface, after displaying the media asset recommendation interface. For example, if the media asset recommendation interface displayed on the display device 200 includes a recommended media asset a, the user may select the media asset a for playing based on the currently displayed media asset recommendation interface, i.e., input a control instruction for playing the recommended media asset item.
According to the difference of the interaction modes supported by the display device 200, the user can input control instructions for playing recommended media items through the different interaction modes. For example, the control device 100 may control the focus cursor to move to select the recommended media asset a in the media asset recommendation interface, may select the recommended media asset a through touch interaction operation, may also input voice content such as "play media asset a" through a voice interaction manner, and may control the display device 200 to play the recommended media asset a.
It should be noted that, the control instruction for playing the recommended media item may also be input based on interfaces other than the media recommendation interface. For example, in a user interface where recommended media items are not displayed, the display device 200 may be controlled to play the designated media items by means of voice interaction, gesture touch operation, or the like, and for such media item playing process, media filtration may also be performed in a manner provided in this embodiment.
After acquiring the control instruction for playing the recommended media item, the display device 200 may extract the recommended media item specified by the control instruction and detect the current device parameter in response to the control instruction. For example, when the user selects recommended asset a for playback, the display device 200 may extract a designated recommended asset item from the control instruction as asset a. 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 h× -65E5G, while by detecting the operating system version, the version parameters may be obtained to be j×ui2.0.
After extracting the recommended media asset item 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 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 the media asset data and updates the upload status according to the play request.
That is, the server 400 may first query the media asset data of the recommended media asset item in response to the play request. When the server 400 queries 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 the media asset ID, the media asset name, etc., 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 media asset ID of the recommended media asset item may be extracted from the play request: 11017041395 the server 400 is further configured to query the server 400 for the asset data according to the asset ID, and when the server 400 stores asset data with an ID 11017041395, that is, asset data with an asset content of "××world 2 nd quarter", the server 400 may further determine, based on the asset data, whether the current display device 200 supports playback of the asset data.
Obviously, when the server 400 queries the media data of the recommended media item, the server 400 may query the media data that is suitable for the recommended media item, or may not query the media data, and when the server 400 queries the media data, the server 400 may determine whether the current display device 200 supports playing of the media data. When no media data is queried, it indicates that the currently recommended media item may not be provided due to offline media or other faults, so the server 400 may send a prompt message to the display device 200 to prompt the user that the current playing 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 supporting status of the device parameter for playing the media asset data according to the data specific such as the type, format, resolution, data volume, etc. of the media asset data. The server 400 may determine the hardware configuration of the current display device 200, that is, determine whether the current display device 200 has sufficient arithmetic processing capability, according to the model version in the device parameters. Meanwhile, the server 400 may also determine whether the current display apparatus 200 is configured with a control program corresponding to a specific play function according to the version parameter, thereby determining 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 locates the low end, the corresponding dominant frequency is low, the number of cores is small, and there is generally no separate image processing module, so that it cannot meet the requirement of playing media data with high resolution. Therefore, when it is determined that the device parameter of the display device 200 is a low-end device parameter, playback cannot be completed for the recommended media items that provide only 4K and 8K resolutions, that is, the support state of the device parameter for playing the media data is determined to be "unsupported". Similarly, for the higher-end display device 200, when the operating system version is low, the playing of the specific media data cannot be supported. If the function of decoding the media data in the ". Rmvb" format is a function added at the time of updating the operating system of the version jxui 2.1, then when the version parameter acquired by the server 400 is jxui 2.0, since the display device 200 is not configured with a system that performs decoding in the ". Rmvb" format, it is also possible to determine that the support state of the device parameter for playing the media data is "unsupported".
After detecting the supporting status of the device parameter to play the media asset data, the server 400 may update the uploading status of the recommended media asset item to the device parameter according to the supporting status. That is, if the device parameter supports playing the media asset data, setting a redis state value corresponding to the recommended media asset item to be 1; if the equipment parameters do not support playing of the media asset data, the redisstate value corresponding to the recommended media asset item is set to be 0. After updating the status of the recommended media item on the device parameter, the server 400 may further store the updated status of the recommended media item, so that when the display device 200 having the same device parameter subsequently plays the recommended media item again, the status of the recommended media item may be directly determined according to the stored redis status value, so as to implement filtering of the recommended media item that does not support playing by the current display device 200.
For example, when the user 1 requests to play the asset a providing only 4K and above of the resolution film source through the low-end display device 200, the server 400 may determine that the current display device 200 does not support playing of the asset a according to the device parameters of the display device 200 and the playing requirement of the asset a. Therefore, the online information of the media asset a to the model of the display device 200 can be updated from the default redis state value of 1 to the redis state value of 0 and stored.
After updating the up status, the server 400 may record the status that the current low-end display device 200 does not support playing the media asset a, so that the user 2 uses the display device 200 with the same model and version parameters to request to display the media asset recommendation interface again, and the media asset a may be filtered, so that the media asset a is not recommended to the display device 200 with the same model and version any more, thereby alleviating the waste of recommendation bits and reducing the invalid operation times of the user.
It can be seen that, in the above embodiment, by controlling the writing time of the online state redis state value, the online state of a plurality of recommended media items for each device parameter can be recorded in the server 400 according to the process of requesting to play the media 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 media assets is approximately 10 tens of thousands, the number of models is thousands, and the number of versions is hundreds of hundreds, according to the number, there may be hundreds of billions keys in rediss, so that under the condition of fewer computing resources, all media assets cannot be enumerated in advance. If the result of the composite media asset is triggered by reading, i.e. the result of the composite media asset is queried when the result is not queried from 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, namely, the media online state is written in redis only if the user truly triggers the detail page of the media and goes offline.
The triggering mode can greatly reduce the number of keys in redis. Firstly, although 10 ten thousand media assets exist, the hot media assets have very obvious head effect and can be basically controlled within 2000; secondly, most of media assets are universal in requirements on models and versions, only media assets with special attributes like 4K, 3D and the like are compared, the problem of model version filtering is solved, the offline state writing of the media assets is triggered, the proportion is about 5%, so that keys which are required to be stored in rediss can be reduced to about 10 ten thousand, and normal support can be achieved by using a redis cluster.
In addition, because the models used by the users have a great aggregation effect, most of the users are concentrated in about 100 main stream models, so the actual key in redis is basically controlled within 5 ten thousand, but the user experience and the operation effect are greatly improved. Since most users will not see this offline recommendation, especially the head position, except for individual users, this is particularly significant for the operation.
It should be noted that, in order to reduce the excessive occupation of the storage space of the server 400 by recording the presence status and make the presence recorded by the server 400 time-efficient, in some embodiments, the server 400 may further set an expiration time for the presence status according to the actual operation rhythm, and when the presence status setting time exceeds the expiration time, the server 400 may delete the record or reset the presence status. For example, the on-line status may set an expiration time of 1 day in redis.
In some embodiments, if the device parameters support playing of the media asset data, the media asset data is sent to the display device 200 so that the display device 200 can normally play the recommended media asset item. And if the device parameters do not support playing the media asset data, sending an offline cue to the display device 200. The offline notification may be in the form of a push message, that is, the server 400 may cause the display device 200 to display the offline notification message after receiving the offline notification. For example, a prompt message "the current device does not support the movie playback, please select another movie" is displayed in the form of a pop-up window. The offline prompt may also be in the form of a control command, i.e., the server 400 may trigger the display device 200 to perform user interface switching, so that the display device 200 switches from the current display interface to the offline prompt interface. In the alert interface, alert words such as "the content has been offline, you can select other content to view" may be displayed.
In some embodiments, after obtaining the media data corresponding to the recommended media item, the server 400 may also send the media data to the display device 200, and determine, through the display device 200, whether to support playing of the media data, where when an abnormal condition occurs in the display device 200 that decoding cannot be performed on the media data, display is abnormal, playing is blocked seriously, and the like, and playing cannot be completed, it is determined that the current display device 200 does not support playing of the media data. At this time, the display device 200 may feed back error information to the server 400, so that the server 400 may update the status of the recommended media items on the device parameters according to the error information.
For example, when the display device 200 that does not support 3D video playing requests to play the 3D film source media asset B, the server 400 may first query the online information of the media asset B for the model of the display device 200, for example, the online information of the media asset B is a default value redis is 1, at this time, the server 400 may send the media asset data to the display device 200, and after receiving the media asset data, the display device 200 performs decoding on the media asset data according to the currently supported playing capability and plays the media asset data. Obviously, since the current display device 200 does not support 3D video playing, the decoding operation cannot be completed in the playing process, and at this time, the display device 200 may feed back error information to the server 400, which indicates 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 the default value redis to be 1 to redis to be 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 media asset arrangement data to the display device 200 to clear invalid recommended media asset items in the media asset recommendation interface when it is determined that the current device parameters do not support playing recommended media asset items. That is, after updating the status of the recommended media items on the device parameters, the server 400 may modify the recommended media layout data of the media recommendation interface according to the updated status, and then feed back the modified recommended media layout data to the display device 200, so that the display device 200 refreshes the media recommendation interface.
For example, as shown in fig. 12, when the display device 200 requests to display the media asset recommendation interface including 5 recommendation bits, respectively displaying the media asset a, the media asset B, the media asset C, the media asset D, and the media asset E, the user 1 controls the display device 200 to request to play the media asset C, and based on the play request, the server 400 determines that the current display device 200 does not support playing the media asset C, at this time, the online state of the media asset C may be modified according to the support state. And deleting C in the original media layout data. And simultaneously, acquiring a medium resource F with higher recommendation degree, and transmitting new recommended medium resource arrangement data formed by the medium resource F, the medium resource B, the medium resource D and the medium resource E to the display equipment 200, so that the display equipment 200 refreshes a medium resource recommendation interface according to the new recommended medium resource arrangement data, namely, as shown in fig. 13, the medium resource A, the medium resource B, the medium resource D, the medium resource E and the medium resource F are displayed on 5 recommendation positions in the refreshed medium resource recommendation interface for a user to select and play.
In addition, after triggering the display device 200 to refresh the media asset recommendation interface, the server 400 also stores the modified recommended media asset arrangement data with the device parameters as indexes. And a new set of media resource recommendation item combination is formed to replace the recommended media resource arrangement data originally used for the current model and version parameters. Thus, when the display devices 200 of the same model and version request to display the media recommendation interface, new recommended media arrangement data can be fed back to the display device 200, so that the display device 200 can directly form the media recommendation interface by adopting the new recommended media arrangement data.
In some embodiments, the online status stored in the server 400 also supports active adjustment, that is, as shown in fig. 14, the server 400 may obtain an adjustment instruction input by an operator for a recommended media item, update the online status of the recommended media item for the device parameter in response to the adjustment instruction, and store the updated online status of the recommended media item for the device parameter.
For example, during the caching period, the up status of the media item is changed, for example, the media item that is originally in the down status under the corresponding model version generates the status value of the down status in redis, and caches the data. However, because of the adjustment of the thematic content, the media asset becomes on-line in the version of the corresponding model, and at this time, the data cached in the redis and the real state deviate. In this case, the server 400 may monitor the arrangement process of the media asset item, and if there is a change in the content under the media asset, it triggers deletion of all key values of the media asset in redis, and gives a new online status, so as to avoid that the content cannot be issued to the display device 200 at the same time.
Based on the foregoing media 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. Wherein the storage module 410 is configured to store media asset data; the communication module 420 is configured to establish a communication connection with the display device 200; the control module 430 is configured to perform the following program steps:

detecting the supporting state of the equipment parameters on the playing media data;
and updating the online state of the recommended media items on the device 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 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:
Acquiring a control instruction input by a user based on a media asset recommendation interface and used for playing recommended media asset items;
responding to the control instruction, extracting a recommended media item designated by the control instruction, and detecting the current equipment parameter;
generating a play request, wherein the play request comprises recommended media resource items and equipment parameters;
sending a play request to a server so that the server inquires media asset data of recommended media asset items according to the play request, detecting a supporting state of equipment parameters on the play media asset data, and updating an online state of the recommended media asset items on the equipment parameters according to the supporting 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 solution, the server 400 and the display device 200 provided in the foregoing embodiments may query the media asset data of the recommended media asset item and detect the supporting condition of the device parameter for playing the media asset data when the display device 200 of one device parameter requests the media asset recommendation interface and plays the recommended media asset item in the media asset recommendation interface, so as to update the status of the recommended media asset item on the device parameter according to the supporting condition. The server 400 may record and maintain the compatibility between the recommended media resource items and the device parameters in real time, so that when other display devices 200 with the same device parameters request the media resource recommendation interface again, the invalid recommended media resource items in the recommended media resource arrangement data are directly filtered according to the uplink state, the problem that the invalid recommended media resource items occupy recommendation positions is solved, and user experience is improved.
The foregoing detailed description of the embodiments is merely illustrative of the general principles of the present application and should not be taken in any way as limiting the scope of the invention. Any other embodiments developed in accordance with the present application without inventive effort are within the scope of the present application for those skilled in the art.
