Fig. 1 is a schematic diagram of an operation scenario between a display device and a control apparatus according to an embodiment. As shown in fig. 1, a user may operate the display device 200 through the smart device 300 or the control apparatus 100.
In some embodiments, the control apparatus 100 may be a remote controller, and the communication between the remote controller and the display device includes infrared protocol communication or bluetooth protocol communication, and other short-range communication modes, and the display device 200 is controlled by a wireless or wired mode. The user may control the display device 200 by inputting user instructions through keys on a remote control, voice input, control panel input, etc.
In some embodiments, a smart device 300 (e.g., mobile terminal, tablet, computer, notebook, etc.) may also be used to control the display device 200. For example, the display device 200 is controlled using an application running on a smart device.
In some embodiments, the display device 200 may also perform control in a manner other than the control apparatus 100 and the smart device 300, for example, the voice command control of the user may be directly received through a module configured inside the display device 200 device for acquiring voice commands, or the voice command control of the user may be received through a voice control device configured outside the display device 200 device.
In some embodiments, the display device 200 is also in data communication with a server 400. The display device 200 may be permitted to make communication connections via a Local Area Network (LAN), a Wireless Local Area Network (WLAN), and other networks. The server 400 may provide various contents and interactions to the display device 200. The server 400 may be a cluster, or may be multiple clusters, and may include one or more types of servers.
In some embodiments, the display device may directly enter the display interface of the signal source selected last time after being started, or the signal source selection interface, where the signal source may be a preset video on demand program, or may be at least one of an HDMI interface, a live tv interface, etc., and after the user selects a different signal source, the display may display the content obtained from the different signal source.
In some embodiments, the signal source that the display device enters after being started is a live television interface, and the display device may acquire live stream data of a default channel of the live television interface from the server, and then play the live stream data, where the default channel may be a channel that the user last viewed.
In some embodiments, the live channel may be a movie live channel, and the server may schedule a plurality of movies for the movie live channel, such that the movie live channel plays the movies sequentially. However, some movies require higher device capabilities, resulting in some televisions with lower configurations or lower software versions that can cause a stuck or even failed playback of the movie, affecting the user's viewing experience. The device capabilities may include, among other things, configuration parameters of the television, such as resolution, range of the speaker, etc.
In order to solve the above problem, when the server issues live stream data to the display device, the server can screen live media assets and only send media assets supported by the display device to play.
In some embodiments, the server that interacts with the display device may be referred to as a terminal-oriented server, and the server on the display device side includes servers other than the terminal-oriented server, such as an operation server, a media asset library, and a device capability library. The operation server is used when operators program live media assets for each live channel; the media asset library is a server for storing media asset information, which may include equipment capabilities required by the media asset; the device capability library is used for storing the device capability information of each type of television, wherein the televisions can jointly determine the types according to the model versions and the software versions of the live television interfaces, and if the model versions of the two televisions are the same, the software versions of the live television interfaces can be considered to be the same, and the two televisions have the same device capability.
In some embodiments, the terminal-oriented server, the operation server, the media asset library, the device capability library, and other servers may be implemented on one device or may be implemented on multiple devices, which is not limited in the present application.
In some embodiments, the content stored in the device capability library is as shown in table 1:
TABLE 1
Referring to table 1, the device capability information may include a plurality of parameters, such as whether it is 4K asset, whether it is DRM asset, whether it is 3D asset, whether it is dolby asset, etc., where the above parameters are determined by both model version and software version, false indicates no, true indicates yes.
The meaning of table 1 is: the model version is TV1.0, and the software version is 01.102.139, the TV does not support the playing of 4k media assets, the playing of DRM media assets, the playing of 3D media assets and the playing of 1080p media assets.
In some embodiments, the device capability information is stored in the form of a collection. The set is illustratively referred to as a first set, denoted F dev . Table 1 corresponds toThe first set is: f (F) dev = {1080p }. For a display device A which does not support 4k playing, supports DRM playing, supports 3D media resource playing, supports dolby visual media resource and supports 1080p media resource, the corresponding set of the device capability information is F dev = { DRM,3D, dolby view, 1080p }. For a display device B supporting 4k playing, DRM playing, 3D media resource playing, dolby visual media resource and 1080p media resource, the corresponding set of the device capability information is F dev = {4k, drm,3d, dolby view, 1080p }. It can be seen that the parameter items in the set to which the device capability information corresponds may be different for different display devices, where the parameter items are elements in the set, such as 4k, drm,3d, dolby view, 1080p. In some embodiments, the content of the media asset data in the media asset library is as shown in table 2:
TABLE 2
| Field name | Field description | Field value example |
| media_id | Media asset ID | 50001001 |
| media_name | Media asset name | “A” |
| duration | Duration of media asset play | 60min |
| url | Media asset play address | xxxxx |
| is_4k | Whether or not 4k media assets | True |
| is_drm | Whether DRM media asset | False |
| is_3d | Whether 3D media assets | True |
| Is_dolby_vision | Whether dolby FOV (visual field medium resource) | False |
| … | … | … |
Referring to table 2, the device capability requirement information may include parameters of whether 4K asset, whether DRM asset, whether 3D asset, whether dolby asset, etc., where asset ID is asset identification, false indicates no, true indicates yes.
The meaning of table 2 is: the media asset ID is 50001001, the media asset name is "A", the media asset play duration is 60 minutes, the media asset play address is xxxxx, the media asset is 4k media asset, and the 3D media asset is not dolby visual media asset.
In some embodiments, the device capability requirement information is stored in a collection.The set is illustratively referred to as a second set, denoted as F req . The second set corresponding to table 2 is: f (F) req = {4k,3d }. It can be seen that the second set corresponding to Table 2 is a subset of display device B, i.eIn this case, the media assets corresponding to table 2 may be successfully played if they are played on the display device B, and will be failed if they are played on the display device a.
In some embodiments, an operator may create a live channel through the operation server, and when creating the live channel, the operator may designate a media asset to be selected for the live channel, and may update the media asset to be selected later. The media assets to be selected are media assets to be selected and played in the live channel, and for display equipment with higher configuration, all media assets to be selected can be played in the live channel, and for display equipment with lower configuration, media assets to be selected with lower requirement for selective playing in the live channel can be configured.
An exemplary method for creating a live channel is as follows: an operator establishes a live channel on an operation server through an OP page, configures the channel to be named as a scientific movie channel, and configures the time for the live broadcast of the channel to be 08:00 of XX month and XX day of XX year and 20:00 of XX month and XX day of XX year and XX month and end time. The operator sets the media asset IDs of 8 movies in the media asset list to be selected of the live channel, and after the configuration is completed, the operation server can generate and display the channel identification, namely the channel ID, of the live channel.
In some embodiments, the operation server generates a resource pool to be selected according to the information of the live channel and the channel identifier of the live channel input by the user, and stores the resource pool according to the channel identifier of the live channel.
In some embodiments, the content included in the candidate resource pool may be as shown in table 3:
TABLE 3 Table 3
Referring to table 3, the resource pool to be selected may include a channel ID of a live channel, a channel name, a channel playing start time, a channel playing end time, and a channel resource list to be selected, where the channel ID is a channel identifier, the channel resource list to be selected is live data to be selected, and the channel ID, the channel name, the channel playing start time, and the channel playing end time are live configuration data.
The meaning of table 3 is: a live channel with a channel ID of 10001, the channel being named "science fiction movie channel", the channel being configured to start playing from XX year XX month XX day 08:00 to XX year XX month XX day 20:00 ending playing, the channel having a media asset ID of 50001001,50001002,50001003,50001004,50001005,50001006,50001007,50001008 for all candidate media assets.
In some embodiments, after configuring one live channel, the operator may continue to configure the candidate resource pool for the next live channel.
After the operator configures the resource pool to be selected of a live channel, if the user plays the live channel, the terminal-oriented server can screen media supported by terminal equipment for playing from the resource pool to be selected for the terminal equipment of the user.
Referring to fig. 2, a flowchart of a method for playing a live channel according to some embodiments, where the method is used for facing a terminal server, as shown in fig. 2, the playing method may include the following steps:
step S110: a live channel play-up request is received from a display device, the live channel play-up request including a channel identification and a device capability identification of the display device.
In some embodiments, the terminal-oriented server extracts the channel identification and the device capability identification of the display device from the live channel play request after receiving the live channel play request.
Step S120: and responding to the live channel playing request, and acquiring live to-be-selected data corresponding to the channel identifiers, wherein each channel identifier corresponds to one set of live to-be-selected data, and the live to-be-selected data comprises a plurality of media identifiers.
In some embodiments, the terminal-oriented server may obtain, from the operation server, a media asset resource pool of a live channel corresponding to the channel identifier according to the channel identifier. The media asset resource pool comprises live broadcast standby data and live broadcast configuration data, the live broadcast standby data comprises a channel standby media asset list, the list comprises media asset identifiers of a plurality of standby media assets, and the live broadcast configuration data comprises a channel ID, a channel name, channel playing start time and channel playing end time.
Step S130: and matching the equipment capability information corresponding to the equipment capability identifiers with the equipment capability requirement information corresponding to each media asset identifier, and screening media asset identifiers successfully matched with the equipment capability requirement information from the live broadcast candidate data.
In some embodiments, the device capability identifier is matched with the media asset identifier, which means that the device capability information corresponding to the device capability identifier is successfully matched with the device capability requirement information corresponding to the media asset identifier, where the successful match may mean that the second set corresponding to the media asset identifier is a subset of the first set corresponding to the device capability identifier.
The device capabilities of display device a are: if_4k=false, if_drm=true, if_3d=true, and if_dolby_vision=false, i.e., the display device a does not support 4K, dolby view, and such a standby media can be played on the display device a as long as the standby media does not require 4K and dolby view.
I.e. display device a may support playback of media assets of the following nature:
(1)is_4k＝False、is_drm＝True、is_3d＝True、Is_dolby_vision＝False；
(2)is_4k＝False、is_drm＝False、is_3d＝True、Is_dolby_vision＝False；
(3)is_4k＝False、is_drm＝True、is_3d＝False、Is_dolby_vision＝False；
(4)is_4k＝False、is_drm＝False、is_3d＝False、Is_dolby_vision＝False。
if one or both of 4k and dolby view are required for the media asset to be selected, the media asset to be selected cannot be played on the display device a.
In some embodiments, the terminal-oriented server obtains device capability information of the display device from a device capability library according to the device capability identifier in the live channel playing request, and obtains the first set.
In some embodiments, the operation server stores the device capability requirement information of each media asset to be selected, and the terminal-oriented server may obtain the device capability requirement information of each media asset to be selected from the operation server to obtain the second set.
In some embodiments, only the media asset identifier and the media asset name of each media asset to be selected are stored in the operation server, and the terminal-oriented server can obtain the equipment capability requirement information of each media asset to be selected from the media asset library according to the media asset ID.
In some embodiments, after obtaining the device capability requirement information of each media resource to be selected and the device capability information of the display device, the terminal-oriented server may match the device capability information with the device capability requirement information, if the matching is successful, the media resource identifier is reserved, and if the matching fails, the media resource identifier is removed.
Referring to fig. 3, a flow chart of a method for screening media candidates according to some embodiments, referring to fig. 3, the method may include the following steps:
step S301: querying a first candidate media asset.
In some embodiments, the terminal-oriented server may obtain the media asset identifier of the first media asset to be selected from the channel candidate list in the live candidate data. For example, referring to table 3, the first candidate is identified as 50001001.
Step S302: the required device capabilities of the current media asset to be selected are queried.
In some embodiments, the terminal-oriented server may obtain, from the media asset library, device capability requirement information corresponding to the media asset identifier according to the media asset identifier. The device capability requirement information indicates the device capability required by the media asset to be selected.
Step S303: and judging whether the display equipment supports equipment capability required by the media resource to be selected.
In some embodiments, if the first set corresponding to the current candidate media asset is the same as the second set corresponding to the display device, the device capability required by the display device to support the candidate media asset is indicated.
In some embodiments, if the first set corresponding to the current candidate media asset is a subset of the second set corresponding to the display device, the device capability required by the display device to support the candidate media asset is indicated.
In some embodiments, if the first set corresponding to the current media asset to be selected is different from the second set corresponding to the display device, and the first set corresponding to the previous media asset to be selected is not a subset of the second set corresponding to the display device, the device capability required by the display device to not support the media asset to be selected is indicated.
Step S304: if so, adding the current media resource to be selected into the scheduling list.
In some embodiments, the display device supports the device capability required by the media asset to be selected, and may arrange a time schedule and add the media asset identifier to the time schedule, where the channel playing start time and the channel playing end time in the time schedule are obtained according to table 3.
Step S305: and judging whether the next media resource to be selected exists.
Step S306: and if the next media resource to be selected exists, processing the next media resource to be selected.
In some embodiments, if there is a next candidate media asset, the process returns to step S303 to start processing the next candidate media asset.
Step S140: and generating live channel data containing the channel identification and the screened media asset identification.
In some embodiments, after all the media assets to be selected are screened, live channel data including channel identifiers and screened media asset identifiers may be generated according to the screened media assets to be selected.
Step S150: and feeding the live channel data back to the display device.
In some embodiments, after feeding back the live channel data to the display device, the display device may begin playing the media asset of the live channel.
To further illustrate the interaction of the display device with the terminal-oriented server and the interaction of the terminal-oriented server with other servers in the above process, fig. 4 shows a schematic diagram of a play-up timing of a live channel according to some embodiments. As shown in fig. 4, if the terminal user plays a live channel on the terminal device, or the display device enters a default live channel after being started, the display device may generate a live channel play request, and send the live channel play request to the terminal-oriented server. Wherein the live channel play request may include a channel identifier and a device capability identifier of the display device, and the device capability identifier may include a model version and a software version shown in table 1.
