The following explains the media asset playing method provided in the embodiment of the present application in detail.
Fig. 7 is a flowchart illustrating a method for playing media assets, which is applied to the display device, and in particular, can be applied to a controller of the display device according to some exemplary embodiments. The following embodiments are explained only taking the display device as an execution subject. Referring to fig. 7, the method may include the following steps:
step 701: and receiving a control display instruction.
The control showing instruction can be sent by the control device under the control of a user.
As an example, in the process of playing the media asset by the display device, the user may send a control display instruction to the display device through the control device, and accordingly, the display device may receive the control display instruction.
Because the step is realized in the process of playing the media assets by the display equipment, the media assets can be played in the display equipment before the control display instruction is received.
In implementation, in response to detecting the play instruction, the display device may send a second request to the server, where the second request includes a media asset identifier of the media asset, and the second request is used to request the server to feed back the first play quality parameter supported by the media asset based on the media asset identifier. And receiving a first play quality parameter supported by the media assets sent by the server. And acquiring a code stream of the media asset and decoding and playing the code stream based on the first playing quality parameter and the reference playing quality parameter supported by the media asset.
Wherein, the asset identifier can be used for uniquely indicating one asset. For example, the asset identifier may be a name, number, etc. of the asset.
The playing quality parameter may be a resolution parameter or a sound quality parameter. As an example, if the currently played media asset is a video, the playing quality parameter may be a resolution parameter. If the currently played media asset is audio, the playing quality parameter may be a sound quality parameter.
The playing instruction can be generated based on the detected triggering operation of the playing control, and the triggering operation can be executed by the user through the control device.
The reference playback quality parameter refers to a playback quality parameter used when the display device is not set after being turned on. As an example, the reference playing quality parameter may also be referred to as a default playing quality parameter, which is a playing quality parameter automatically used by default after the display device is turned on.
That is, if the display device detects a play instruction, it may be considered that the user wants to play the asset, and a second request may be sent to the server, where the second request includes an asset identifier of the asset. After receiving the second request, the server may obtain, based on the asset identifier, a first play quality parameter supported by the asset indicated by the asset identifier, and feed back the obtained first play quality parameter supported by the asset to the display device. After receiving the first play quality parameter supported by the media asset fed back by the server, the display device can acquire a code stream of the media asset and perform decoding play according to the first play quality parameter supported by the media asset and the reference play quality parameter.
In some embodiments, after the user turns on the display device, the display device may display a first interface, where the first interface includes a plurality of asset controls, and each asset control corresponds to one asset. If the display device detects that the triggering operation of one of the plurality of asset controls indicates that the user selects the asset, the display device can acquire an asset identifier of the asset and then send an asset information acquisition request to the server, wherein the asset information acquisition request comprises the asset identifier of the asset, and the asset information acquisition request is used for requesting the server to feed back asset information of the asset corresponding to the asset identifier. After receiving the request for obtaining the media information, the server can obtain the media information corresponding to the media identifier based on the media identifier, wherein the media information includes a poster, a play address and the like of the media. After receiving the media information, the display device can switch from the first interface to display the second interface, and can display posters, brief introduction and the like of the media information, and can also display an option control and a play control on the second interface.
As an example, if the user wants to play the media asset, a triggering operation on the play control may be executed through the control device, a play instruction may be generated based on the triggering operation, if the display device detects the play instruction, a second request including the media asset identifier may be sent to the server, and after the server receives the second request, since the server stores a plurality of media asset identifiers and a first play quality parameter supported by each media asset identifier, the server may directly obtain, according to the media asset identifier, the first play quality parameter supported by the media asset corresponding to the media asset identifier. Then the server feeds back the determined first playing quality parameter supported by the media asset to the display device, and the display device can receive the first playing quality parameter supported by the media asset sent by the server.
In implementation, based on the first play quality parameter and the reference play quality parameter supported by the media asset, acquiring a code stream of the media asset and performing decoding play may include the following implementation manners:
in some embodiments, if the first playback quality parameter includes a reference playback quality parameter, a third request is sent to the server, where the third request includes a media asset identifier of the media asset and the reference playback quality parameter, and the third request is used to request the server to feed back, based on the media asset identifier and the reference playback quality parameter, a code stream of the media asset under the reference playback quality parameter. And receiving a code stream of the media assets fed back by the server under the reference playing quality parameter, and decoding and playing the code stream.
That is, if the asset supports the reference playback quality parameter, a third request including the asset identifier and the reference playback quality parameter may be transmitted to the server. After receiving the third request, the server may determine, based on the media asset identifier and the reference playback quality parameter, a code stream of the media asset under the reference playback quality parameter. And then feeding back the determined code stream to the display equipment, and the display equipment receives the code stream of the media asset under the reference playing quality parameter sent by the server and decodes and plays the received code stream to realize the playing of the media asset.
In some embodiments, as can be seen from the above embodiments, each asset identifier in the server may store multiple sets of corresponding relationships correspondingly. For a media asset, the server can also store multiple code streams of the media asset, and each code stream corresponds to a group of corresponding relations of the media asset. For example, for the asset X, assuming that 3 sets of corresponding relationships, namely 1080P and dolby vision, 1080P and HDR, 720P and SDR, are stored in the server, 3 kinds of code streams corresponding to the asset X may also be stored, one set is the code stream of the asset X under 1080P and dolby vision, one set is the code stream of the asset X under 1080P and HDR, and one set is the code stream under 720P and SDR.
As an example, assume that the first playback quality parameter is a resolution parameter. Assuming that resolution parameters supported by the media asset X are 4K, 1080P and 720P, and a reference resolution parameter is 1080P, it may be determined that the first playback quality parameter includes the reference playback quality parameter, and a third request including a media asset identifier X and the reference resolution parameter 1080P may be sent to the server, and after receiving the third request, the server may determine, according to the media asset identifier X, a plurality of code streams corresponding to the media asset, and then determine, according to 1080P, a code stream of the media asset X under 1080P. If 1080P and Dolby vision, and 1080P and HDR code streams exist under 1080P, one code stream can be randomly acquired and fed back to the display device, and a default code stream can also be fed back to the display device. And the display equipment receives the code stream of the media asset X under the reference resolution parameter 1080P, which is sent by the server, and decodes and plays the received code stream to realize the playing of the media asset.
In this implementation manner, if the media asset supports the reference playing quality parameter, the code stream corresponding to the reference playing quality parameter supported by the media asset can be directly acquired and decoded and played. Therefore, the quality of the played media assets is more in line with the watching habits of general users, so that the users can enjoy good visual experience.
In other embodiments, if the first playing quality parameter does not include the reference playing quality parameter, a fourth request is sent to the server in response to that a maximum second playing quality parameter supported by the display device is greater than or equal to a maximum first playing quality parameter in the first playing quality parameter, the second playing quality parameter is used for indicating the playing quality of the media assets played in the display device, the fourth request includes media asset identifiers of the media assets and the maximum first playing quality parameter, and the fourth request is used for requesting the server to feed back code streams of the media assets under the maximum first playing quality parameter based on the media asset identifiers and the maximum first playing quality parameter. And receiving a code stream of the media assets fed back by the server under the maximum first playing quality parameter, and decoding and playing the code stream.
The maximum second playing quality parameter is the second playing quality parameter which enables the playing quality of the media asset to be the best when the media asset is played on the display device in the second playing quality parameters supported by the display device. For example, if the second playback quality parameter is a resolution parameter, the maximum second playback quality parameter is a second playback quality parameter that maximizes the definition of the media asset when playing back on the display device among the resolution parameters supported by the display device.
The maximum first playing quality parameter is the first playing quality parameter which enables the playing quality of the media asset to be the best in the first playing quality parameters supported by the media asset. For example, if the first playback quality parameter is a resolution parameter, the maximum first playback quality parameter is the first playback quality parameter that maximizes the definition of the asset among the resolution parameters supported by the asset.
That is to say, under the condition that the media asset does not support the reference playback quality parameter, since the display device can support the playback quality parameter smaller than the maximum second playback quality parameter supported by the display device, if the maximum second playback quality parameter supported by the display device is greater than or equal to the maximum first playback quality parameter in the first playback quality parameters, it can be considered that the first playback quality parameter display device supported by the media asset supports all the playback quality parameters, that is, any code stream of the media asset can be played on the display device. In this way, a fourth request including the media asset identifier of the media asset and the maximum first playing quality parameter may be sent to the server, and after receiving the fourth request, the server may determine, based on the media asset identifier and the maximum first playing quality parameter, a code stream supported by the media asset under the maximum first playing quality parameter. And then feeding back the determined code stream to the display equipment, and the display equipment receives the code stream of the media asset under the maximum first playing quality parameter sent by the server and decodes and plays the received code stream to realize the playing of the media asset.
As an example, assume that the first playback quality parameter is a resolution parameter. Assuming that the resolution parameters supported by the asset X are 4K, 720P, and 360P, the reference resolution parameter is 1080P, and the maximum resolution parameter supported by the display device is 4K, it may be determined that the reference playback quality parameter is not included in the first playback quality parameter, and the maximum resolution parameter supported by the display device is 4K equal to the maximum resolution parameter supported by the asset X, which may be considered that the display device can support all the resolution parameters supported by the asset X. Therefore, a fourth request comprising the media asset identifier X and the maximum resolution parameter 4K may be sent to the server, and after receiving the fourth request, the server may determine, according to the media asset identifier X, a plurality of code streams corresponding to the media asset, and then determine, according to 4K, a code stream of the media asset X at 4K. If there are three code streams of 4K and dolby vision, 4K and HDR, and 4K and SDR under 4K, one code stream can be randomly acquired and fed back to the display device. And the display equipment receives the code stream of the media asset X under the maximum resolution parameter 4K, which is sent by the server, and decodes and plays the received code stream to realize the playing of the media asset.
In this implementation manner, if the media asset does not support the reference playback quality parameter, the code stream corresponding to the maximum first playback quality parameter supported by the media asset can be acquired for decoding playback on the premise of ensuring the support of the display device. Therefore, the quality of the played media assets is higher than the reference playing quality parameter, and better experience is brought to the user.
In still other embodiments, if the first playing quality parameter does not include the reference playing quality parameter, in response to that the maximum second playing quality parameter supported by the display device is smaller than the maximum first playing quality parameter in the first playing quality parameter, if the first playing quality parameter includes the maximum second playing quality parameter, a fifth request is sent to the server, where the second playing quality parameter is used to indicate the playing quality of the media asset played in the display device, the fifth request includes a media asset identifier of the media asset and the maximum second playing quality parameter, and the fifth request is used to request the server to feed back a code stream of the media asset under the maximum second playing quality parameter based on the media asset identifier and the maximum second playing quality parameter. And receiving a code stream of the media assets fed back by the server under the maximum second playing quality parameter, and decoding and playing the code stream.
That is to say, under the condition that the media asset does not support the reference playback quality parameter, since the display device may support the playback quality parameter smaller than the maximum second playback quality parameter supported by the display device, if the maximum second playback quality parameter supported by the display device is smaller than the maximum first playback quality parameter in the first playback quality parameters, it may be considered that the display device does not support the maximum first playback quality parameter supported by the media asset, that is, the code stream corresponding to the maximum first playback quality parameter supported by the media asset cannot be played on the display device. In this case, if the maximum second playback quality parameter supported by the display device also supports the media asset, a fifth request including a media asset identifier of the media asset and the maximum second playback quality parameter may be sent to the server, and after receiving the fifth request, the server may determine, based on the media asset identifier and the maximum second playback quality parameter, a code stream supported by the media asset under the maximum second playback quality parameter. And then feeding back the determined code stream to the display equipment, and the display equipment receives the code stream of the media asset under the maximum second playing quality parameter sent by the server and decodes and plays the received code stream to realize the playing of the media asset.
As an example, assume that the first playback quality parameter is a resolution parameter. Assuming that resolution parameters supported by the media asset X are 4K, 720P, and 360P, a reference resolution parameter is 1080P, and a maximum resolution parameter supported by the display device is 720P, it may be determined that the first playback quality parameter does not include the reference playback quality parameter, and the maximum resolution parameter supported by the display device is 720P smaller than the maximum resolution parameter 4K supported by the media asset X, and it may be considered that the display device cannot play a code stream under the maximum resolution parameter 4K supported by the media asset X. In this case, if the maximum second playback quality parameter supported by the display device also supports the media asset, a fifth request including a media asset identifier X and a maximum second playback quality parameter 720P may be sent to the server, and after receiving the fifth request, the server may determine a plurality of code streams corresponding to the media asset according to the media asset identifier X, and then determine a code stream of the media asset X under 720P according to 720P. If there are 720P and HDR, and 720P and SDR code streams under 720P, one code stream can be randomly obtained and fed back to the display device. And the display equipment receives the code stream of the media asset X, which is sent by the server, under the maximum resolution parameter 720P supported by the display equipment, and decodes and plays the received code stream to realize the playing of the media asset.
In this implementation manner, if the media asset does not support the reference playback quality parameter and the display device cannot play the code stream of the maximum first playback quality parameter supported by the media asset, if the first playback quality parameter supported by the media asset includes the maximum second playback quality parameter supported by the display device, the code stream corresponding to the maximum second playback quality parameter supported by the display device may be obtained for decoding and playing. Therefore, although the quality of the played media assets is not high, the played media assets are the highest playing quality which can be supported by the display device, the situation that code streams with poor playing quality appear in the display device can be avoided, and the playing quality of the played video can be ensured.
Step 702: and responding to the control display instruction, and acquiring a first play effect parameter supported by the currently played media asset, wherein the first play effect parameter is used for indicating the play effect of the media asset.
The playing effect parameter can be a picture quality parameter or a sound effect parameter.
As an example, if the currently played media asset is a video, the playing effect parameter may be a picture quality parameter and/or a sound effect parameter. If the currently played media asset is audio, the playing effect parameter may be a sound effect parameter.
As an example, if the currently played media asset is a video and the playing quality parameter is a resolution parameter, the playing effect parameter is an image quality parameter and/or a sound effect parameter; if the currently played media asset is audio and the playing quality parameter is a sound quality parameter, the playing effect parameter is a sound effect parameter.
In implementation, if a control display instruction is received, it may be considered that a user wants to switch a first play effect parameter of a currently played media asset, but if the currently played media asset does not support a certain play effect parameter, the switching cannot be implemented, and therefore, the first play effect parameter supported by the currently played media asset needs to be obtained first.
In implementation, the specific implementation of obtaining the first play effect parameter supported by the currently played media asset may include: and sending a first request to a server, wherein the first request comprises a media asset identifier of media assets and a current first playing quality parameter, the first playing quality parameter is used for indicating the playing quality of the media assets, and the first request is used for indicating the server to feed back a first playing effect parameter supported by the media assets based on the media asset identifier and the first playing quality parameter. And receiving a first play effect parameter supported by the media assets fed back by the server under the first play quality parameter.
That is, after receiving the control display instruction, the display device may send a first request to the server, where the first request may include a media asset identifier of a currently playing media asset and a current first playing quality parameter. After receiving the first request, the server may obtain a first play effect parameter supported by the currently played media asset under the current first play quality parameter based on the media asset identifier and the current first play quality parameter, and feed back the first play effect parameter to the display device.
In some embodiments, the server may store a plurality of asset identifiers of assets, and may also store a correspondence between a first play quality parameter and a first play effect parameter of each asset, that is, each asset identifier may store a plurality of sets of correspondences, where each set of correspondences includes a first play quality parameter and a first play effect parameter.
As an example, assuming that a media asset X can support a first playing quality parameter a and a first playing quality parameter B, can support a first playing effect parameter a and a first playing effect parameter B under the first playing quality parameter a, and can only support the first playing effect parameter a under the first playing quality parameter B, for the media asset X, 3 sets of corresponding relationships may be stored in the server, where the first set is the first playing quality parameter a and the first playing effect parameter a, the second set is the first playing quality parameter a and the first playing effect parameter B, and the third set is the first playing quality parameter B and the first playing effect parameter a.
Illustratively, if the currently played media asset is a video, the first playing quality parameter is a resolution parameter, and the first playing effect parameter is an image quality parameter. It is assumed that resolution parameters supported by the asset X are 1080P and 720P, and at 1080P, picture quality parameters supported by the asset X are dolby vision and HDR (High-Dynamic Range), and at 720P, picture quality parameters supported by the asset X are SDR (Software Defined Radio). Then for asset X, there may be 3 sets of correspondences stored in the server, the first set being 1080P and dolby vision, the second set being 1080P and HDR, and the third set being 720P and SDR.
In some embodiments, after receiving the first request, the server may directly obtain a plurality of sets of corresponding relationships corresponding to the media asset according to the media asset identifier, then determine, according to the current first playing quality parameter, a first playing effect parameter corresponding to the current first playing quality parameter from the corresponding relationships, send the determined first playing effect parameter to the display device as a first playing effect parameter supported by the media asset under the current first playing quality parameter, and the display device may obtain the first playing effect parameter supported by the currently played media asset under the current first playing quality parameter.
As an example, assuming that a media asset identifier received by the server is X, and the current first playing quality parameter is a first playing quality parameter a, according to the media asset identifier, the server may determine a corresponding relationship between 3 sets of the first playing quality parameter a and a first playing effect parameter a, the first playing quality parameter a and a first playing effect parameter B, and the first playing quality parameter B and the first playing effect parameter a. Then, according to the first playing quality parameter a, the first playing effect parameter corresponding to the first playing quality parameter a can be determined to be the first playing effect parameter a and the first playing effect parameter b from the 3-group corresponding relationship. And then the server determines the first playing effect parameter a and the first playing effect parameter b as a first playing effect parameter supported by the currently played media asset under the current first playing quality parameter, and feeds the first playing effect parameter back to the display device, and the display device can acquire the first playing effect parameter supported by the currently played media asset under the current first playing quality parameter.
Illustratively, if the currently played media asset is a video, the first playing quality parameter is a resolution parameter, and the first playing effect parameter is an image quality parameter. Assuming that a media asset identifier received by the server is X, a current resolution parameter is 1080P, according to the media asset identifier, the server may determine a corresponding relationship between 1080P and 3 groups of dolby vision, 1080P and HDR, 720P and SDR, then according to 1080P, it may determine that an image quality parameter corresponding to the current resolution parameter is dolby vision and HDR, the server may determine dolby vision and HDR as a first playing effect parameter of the media asset X at 1080P, and feed back dolby vision and HDR to the display device, and the display device may acquire image quality information supported by the currently played video at the current resolution.
In other embodiments, the server may store a plurality of asset identifiers of assets, and may further store a corresponding relationship between a first playing quality parameter of each asset and a first playing effect parameter, that is, each asset identifier may store a plurality of groups of corresponding relationships, each group of corresponding relationships includes one first playing quality parameter and two first playing effect parameters, and the two first playing effect parameters are a parameter related to an image of a video and a parameter related to an audio of the video, respectively, that is, the two first playing effect parameters are an image quality parameter and an audio effect parameter, respectively.
Illustratively, if the currently played media asset is a video, the first playing quality parameter is a resolution parameter, and the first playing effect parameter is a sound effect parameter and an image quality parameter. It is assumed that resolution parameters supported by the asset X are 1080P and 720P, image quality parameters supported by the asset X are dolby vision and HDR (High-Dynamic Range) under 1080P, sound effect parameters supported by the asset X are dolby sound and panoram sound, image quality parameters supported by the asset X are SDR (Software Defined Radio) under 720P, and sound effect parameters supported by the asset X are panoram sound. Then for asset X, there may be 3 sets of correspondences stored in the server, the first set being 1080P, dolby vision and dolby sound, the second set being 1080P, dolby vision and panned sound, the third set being 1080P, HDR and dolby sound, the fourth set being 1080P, HDR and panned sound, the fifth set being 720P, SDR and panned sound.
As an example, after receiving the first request, the server may directly obtain a plurality of sets of corresponding relationships corresponding to the media asset according to the media asset identifier, then determine, according to the current first playing quality parameter, a first playing effect parameter corresponding to the current first playing quality parameter from the corresponding relationships, send the determined first playing effect parameter to the display device as a first playing effect parameter supported by the media asset under the current first playing quality parameter, and the display device may obtain the first playing effect parameter supported by the currently played media asset under the current first playing quality parameter.
Illustratively, if the currently played media asset is a video, the first playing quality parameter is a resolution parameter, and the first playing effect parameter is a sound effect parameter and an image quality parameter. Assuming that the asset identifier received by the server is X, the current resolution parameter is 1080P, based on the asset identification, the server can determine 4-set correspondence of 1080P, dolby vision and dolby sound, 1080P, dolby vision and panned sound, 1080P, HDR and dolby sound, and 1080P, HDR and panned sound, then the image quality parameters corresponding to the current resolution parameters may be determined to be dolby vision and HDR from 1080P, the sound effect parameters corresponding to the current resolution are dolby sound and panoramic sound, the server can determine dolby vision and HDR, and dolby sound and panoramic sound as the first playing effect parameters of the media asset X under 1080P, and the dolby vision and HDR, and the dolby sound effect and the panoramic sound are fed back to the display equipment, and the display equipment can acquire the image quality information and the sound effect information supported by the currently played video under the current resolution.
Step 703: and determining a target playing effect parameter based on the first playing effect parameter and a second playing effect parameter supported by the display equipment, wherein the second playing effect parameter is used for indicating the playing effect of playing the media assets in the display equipment, and the target playing effect parameter is contained in the first playing effect parameter and the second playing effect parameter at the same time.
The target playing effect parameter is a playing effect parameter determined from the intersection of the first playing effect parameter and the second playing effect parameter, and the target playing effect parameter is included in both the first playing effect parameter and the second playing effect parameter. That is, the target play effect parameter is included in both the first play effect parameter and the second play effect parameter, i.e., the target play effect parameter is a play effect parameter supported by the display device and the currently played media asset.
The second play effect parameter supported by the display device may be set by a technician before the display device leaves a factory, and may be stored in the server. For example, the display device may send a parameter acquisition request to the server, where the parameter acquisition request includes a device identifier of the display device. After receiving the parameter obtaining request, the server may determine, based on the device identifier of the display device, a second playing effect parameter supported by the display device, and feed back the determined second playing effect parameter to the display device.
In an implementation, determining a specific implementation of the target play effect parameter based on the first play effect parameter and the second play effect parameter supported by the display device may include: and determining the intersection of the first playing effect parameter and the second playing effect parameter supported by the display equipment to obtain the candidate playing effect parameter. And if the number of the candidate playing effect parameters is multiple, determining the candidate playing effect parameter with the minimum arrangement sequence number in the multiple candidate playing effect parameters as the target playing effect parameter. And if the number of the candidate playing effect parameters is one, determining the candidate playing effect parameters as the target playing effect parameters.
As an example, the candidate playing effect parameter is an intersection of the first playing effect parameter and the second playing effect parameter, that is, the candidate playing effect parameter is a playing effect parameter that is supported by the display device and the currently playing media asset at the same time.
Because the first playing effect parameter supported by the media asset under the first playing quality parameter is not necessarily supported by the display device, for the first playing effect parameter unsupported by the display device, the display device cannot play the code stream under the first playing effect parameter unsupported by the display device, so that the user cannot watch the media asset. Therefore, it is necessary to determine an intersection of a first playing effect parameter supported by the media asset under the first playing quality parameter and a second playing effect parameter supported by the display device, so as to obtain a candidate playing effect parameter. And selecting the playing effect parameter which enables the playing effect of the currently played media asset to be the best from the candidate playing effect parameters as a target playing effect parameter.
Illustratively, the play effect parameter is assumed to be a picture quality parameter. Assuming that the first play effect parameters supported by the media asset under the first play quality parameters include dolby vision, HDR, and SDR and the second play effect parameters supported by the display device include dolby vision and HDR, it may be determined that the intersection of the first play effect parameters and the second play effect parameters are dolby vision and HDR, i.e., the candidate play effect parameters are dolby vision and HDR.
In some embodiments, the display device stores a ranking number of the supported second play effect parameters, where the ranking number is inversely related to the play effect corresponding to the corresponding second play effect parameter. That is, the smaller the sequence number is, the better the playing effect corresponding to the corresponding second playing effect parameter is.
As an example, if the play effect parameter is a picture quality parameter, assuming that the second play effect parameter supported by the display device includes dolby vision, HDR, and SDR, and the arrangement number of dolby vision is 1, the arrangement number of HDR is 2, and the arrangement number of SDR is 3, it can be determined that the order of the play effects from good to bad is dolby vision, HDR, and SDR.
In some embodiments, if the number of the candidate play effect parameters is multiple, the target play effect parameter that makes the play effect of the media asset best can be determined from the multiple; if there is one candidate playing effect parameter, the candidate playing effect parameter can be directly determined as the target playing effect parameter.
Continuing with the above example, it is assumed that the playback effect parameter is an image quality parameter, the candidate playback effect parameters include dolby vision and HDR, and the arrangement number of dolby vision is 1 and the arrangement number of HDR is 2 in the arrangement numbers of the second playback effect parameters supported by the display device. Thus, the candidate playback effect parameter with the smallest arrangement number can be determined as dolby vision, which is a candidate image quality parameter that makes the image quality effect of the media asset presentation the best and the clearest, and can be determined as the target playback effect parameter. Assuming that the candidate play effect parameters include only dolby vision, dolby vision may be directly determined as the target play parameter.
In some embodiments, the playing effect parameter and the playing quality parameter are two different playing parameters, both of which have an influence on the audio-visual effect during the playing of the media asset, and one playing quality parameter and one playing effect parameter correspond to the same code stream. For the media asset corresponding to the same media asset identifier, multiple first playing quality parameters can be supported, for any one supported first playing quality parameter, multiple code streams meeting any one playing quality parameter can be stored in the server, and each code stream corresponds to different playing effect parameters; or, for the media asset corresponding to the same media asset identifier, multiple first playing effect parameters may be supported, and for any one of the supported first playing effect parameters, multiple code streams satisfying the any one of the playing quality parameters may be stored in the server, and each code stream corresponds to a different playing quality parameter.
For example, assume that the playback effect parameter is a picture quality parameter and the playback quality parameter is a resolution parameter. It is assumed that the first play effect parameters supported by the asset corresponding to the asset identifier a include dolby vision, HDR, and SDR, and the supported first play quality parameters include 4K, 720P, and 360P. The code stream stored in the server corresponding to the media asset identifier a includes: the video coding method comprises the steps of coding a video stream with a dolby vision and a resolution parameter of 4K, coding a video stream with a dolby vision and a resolution parameter of 720P, coding a video stream with a dolby vision and a resolution parameter of 360P, coding a video stream with an HDR and a resolution parameter of 4K, coding a video stream with an HDR and a resolution parameter of 720P, coding a video stream with an HDR and a resolution parameter of 360P, coding a video stream with an SDR and a resolution parameter of 4K, coding a video stream with an SDR and a resolution parameter of 720P, and coding a video stream with an SDR and a resolution parameter of 360P.
In other embodiments, the same stream corresponds to one play quality parameter and two play effect parameters. For example, it is assumed that the playback effect parameter is a sound effect parameter and a picture quality parameter, and the playback quality parameter is a resolution parameter. Assume that the first image quality parameters supported by the media asset corresponding to the media asset identifier a include dolby vision and HDR, the first supported sound effect parameters include dolby sound and panorar, and the first supported resolution parameters include 4K and 1080P. The code stream stored in the server corresponding to the media asset identifier a includes: the image quality parameter is dolby vision, the sound effect parameter is a code stream with dolby sound and a resolution parameter of 4K, the image quality parameter is dolby vision, the sound effect parameter is a code stream with dolby sound and a resolution parameter of 1080P, the image quality parameter is dolby vision, the sound effect parameter is a code stream with panoramic sound and a resolution parameter of 4K, the image quality parameter is dolby vision, the sound effect parameter is a code stream with panoramic sound and a resolution parameter of 1080P, the image quality parameter is HDR, the sound effect parameter is a code stream with dolby sound and a resolution parameter of 1080P, the image quality parameter is HDR, the sound effect parameter is a code stream with panoramic sound and a resolution parameter of 4K, the image quality parameter is HDR, the sound effect parameter is panoramic sound and a resolution parameter of 1080P.
In some embodiments, the playback effect parameter may be a picture quality parameter, and the playback quality parameter may be a resolution parameter. In a corresponding example, the code stream may include multiple image quality parameters at the same resolution, and after receiving a control display instruction of a user, a control name corresponding to the code stream with the best image quality effect at the current resolution may be displayed.
Step 704: and displaying the control corresponding to the target playing effect parameter.
In some embodiments, after the target play effect parameter is determined, a control corresponding to the target play effect parameter may be presented in a control list, so as to facilitate selection by a user.
For example, referring to fig. 8, assuming that the target play effect parameter is a dolby horizon, a control corresponding to the dolby horizon may be presented in a control list of the display device.
In some embodiments, as shown in fig. 8, it is assumed that the playback effect parameter is a picture quality parameter and the playback quality parameter is a resolution parameter. In the current resolution, for example, when the first image quality parameter includes dolby vision, HDR, and SDR, and the second image quality parameter includes dolby vision and HDR, the target image quality parameter may be determined to be dolby vision that maximizes the image quality effect of the media asset, and a corresponding image quality control "dolby view" may be displayed according to dolby vision.
In some embodiments, as shown in fig. 8, it is assumed that the playback effect parameter is a picture quality parameter and the playback quality parameter is a resolution parameter. In the current resolution, for example, when the first image quality parameter includes dolby vision and SDR, and the second image quality parameter includes dolby vision, HDR, and SDR, the target image quality parameter may be determined to be dolby vision that maximizes the image quality effect of the media asset, and a corresponding image quality control "dolby view" may be displayed according to dolby vision.
In some embodiments, as shown in fig. 9, it is assumed that the playing effect parameter is a sound effect parameter, and the playing quality parameter is a resolution parameter. Under the current resolution, for example, when the first sound effect parameter includes the dolby sound effect, the a sound effect and the B sound effect, and the second sound effect parameter includes the dolby sound effect and the B sound effect, the target sound effect parameter can be determined to be the best dolby sound effect of the media asset, and the corresponding sound effect control "dolby sound effect" can be displayed according to the dolby sound effect.
In some embodiments, as shown in fig. 10, it is assumed that the playback effect parameter is a picture quality parameter and the playback quality parameter is a resolution parameter. In the current resolution, for example, when the first picture quality parameter includes dolby vision, HDR, and SDR, and the second picture quality parameter includes HDR and SDR, the target picture quality parameter is HDR that makes the picture quality effect of the medium best, and the corresponding picture quality control "HDR" may be displayed according to the HDR.
In some embodiments, as shown in fig. 10, it is assumed that the playback effect parameter is a picture quality parameter and the playback quality parameter is a resolution parameter. In the current resolution, for example, when the first picture quality parameter includes HDR and SDR and the second picture quality parameter includes dolby vision, HDR and SDR, the target picture quality parameter is HDR that makes the picture quality effect of the media asset the best, and the corresponding picture quality control "HDR" may be displayed according to the HDR.
In some embodiments, as shown in fig. 11, if there are two target playback effect parameters, which are the image quality parameter and the audio effect parameter, both the two target playback effect parameters can be displayed on the display screen. Assuming that the image quality parameter is HDR and the sound effect parameter is panoramic sound, the image quality control "HDR" and the sound effect control "panoramic sound" may be respectively displayed in a control list of the display device.
In some embodiments, if the playback effect parameter is a picture quality parameter, in the embodiments of the present application, a picture quality parameter with the best picture quality effect may be selected and displayed to the user; or, if the playing effect parameter is a sound effect parameter, in the embodiment of the present application, a sound effect parameter with the best sound effect may be selected and displayed to the user; alternatively, if the playback effect parameters are the image quality parameters and the sound effect parameters, in the embodiment of the present application, the image quality parameters with the best image quality and the sound effect parameters with the best sound effect may be selected and displayed to the user. Namely, by the method of the embodiment of the application, the playing effect parameter which enables the playing effect of the media assets to be the best can be determined, and the control is displayed to the user, so that the user can quickly switch to the code stream with the best playing effect to play, the operation of the user is reduced, and the use experience of the user is improved.
Further, if the control list further includes a switching control corresponding to the first play quality parameter, in response to detecting a trigger operation on the switching control, an option corresponding to a candidate play quality parameter is displayed, where the candidate play quality parameter is used to indicate a play quality parameter supported by the currently played media asset on the display device. Responding to the selection operation of the option corresponding to any one of the candidate playing quality parameters, and acquiring the code stream of the media asset under any one of the candidate playing quality parameters based on the media asset identification and any one of the candidate playing quality parameters. And decoding and playing the acquired code stream.
Wherein the triggering operation of the switching control can be executed by the user through the control device.
As an example, the candidate playback quality parameter is an intersection of the first playback quality parameter and the second playback quality parameter, that is, the candidate playback quality parameter is a playback quality parameter that is supported by the display device and the currently played media asset at the same time. Wherein the second playing quality parameter is used for indicating the playing quality of the playing media assets in the display device.
As an example, different current resolutions may be selected by switching the control, and image quality effect parameters supported by corresponding code streams may be different in different resolutions.
That is, if the control list further includes a switching control corresponding to the first playing quality parameter, if the triggering operation on the switching control is detected, it indicates that the user wants to switch the first playing quality parameter of the currently played media asset. The display device can display the options corresponding to the candidate playing quality parameters, and if the selection operation of the option corresponding to any candidate playing quality parameter is detected, the code stream of the media asset under the selected candidate playing quality parameter can be acquired.
As an example, referring to fig. 11, assuming that the playback quality parameter is a resolution parameter, a switching control corresponding to the resolution parameter may be displayed on the display device, and when the switching control is displayed on the display device, the switching control may be displayed as a "definition" control, where the control corresponds to settings of different resolutions. The resolution ratio during the initial media asset playing can be preset by a server, or can be determined according to the bandwidth of the display device and the current network, and a user can switch the resolution ratio of the media asset through the definition control, so that code streams at different resolution ratios can be played.
In some embodiments, after detecting the trigger operation of the switching control, the display device may determine, according to a first play quality parameter supported by the media asset and a maximum second play quality parameter supported by the display device, a play quality parameter supported by both the media asset and the display device, that is, a candidate play quality parameter. And then displaying options corresponding to each candidate playing quality parameter, if the selection operation of the option of any candidate quality playing parameter is detected, acquiring a code stream of the media asset under any candidate playing quality parameter based on the media asset identifier and the selected any candidate quality playing parameter, and decoding and playing the acquired code stream.
The maximum second playing quality parameter is the second playing quality parameter which enables the playing quality of the media assets to be the highest in the second playing quality parameters supported by the display equipment. For example, if the second playback Quality parameter is a sound Quality parameter, assuming that the sound Quality parameters supported by the display device include an HQ (High Quality) sound effect and an SQ (Super Quality) sound effect, the maximum sound Quality parameter can be determined to be SQ, where the maximum sound Quality parameter is the sound Quality parameter with the best audio-visual effect.
As an example, determining a specific implementation of the candidate playback quality parameter based on the first playback quality parameter supported by the media asset and the maximum second playback quality parameter supported by the display device may include: and if the first playing quality parameters supported by the media assets comprise first playing quality parameters which are greater than the maximum second playing quality parameter, determining the first playing quality parameters except the first playing quality parameters which are greater than the maximum second playing quality parameter in the first playing quality parameters supported by the media assets as candidate playing quality parameters. And if the first playing quality parameters supported by the media assets do not comprise the first playing quality parameters which are larger than the maximum second playing quality parameter, determining the first playing quality parameters supported by the media assets as candidate playing quality parameters.
That is, if the first playback quality parameters supported by the asset include the first playback quality parameters that are not supported by the display device, the first playback quality parameters that are not supported by the display device in the first playback quality parameters supported by the asset may be deleted, and since the remaining playback quality parameters are smaller than the maximum second playback quality parameters supported by the display device, that is, the remaining playback quality parameters are supported by the display device, the remaining playback quality parameters may be determined as the candidate playback quality parameters. If the first playing quality parameters supported by the media assets are all smaller than or equal to the maximum second playing quality parameters supported by the display equipment, namely the first playing quality parameters supported by the media assets are all supported by the display equipment, therefore, the first playing quality parameters supported by the media assets can be directly determined as candidate playing quality parameters.
Illustratively, the media asset is taken as a video, and the first playing quality parameter is taken as a resolution parameter. It is assumed that the supported resolution parameters of the media assets are 4K, 1080P and 720P, and the supported maximum resolution parameter of the display device is 1080P. It may be determined that the resolution parameters supported by the media asset include 4K that is not supported by the display device, and the others are 1080P and 720P, and since the maximum resolution parameter supported by the display device is 1080P, the display device may also support 720P, and therefore, resolution parameters other than 4K, that is, 1080P and 720P, in the resolution parameters supported by the media asset may be determined as candidate playback quality parameters. It is assumed that the supported resolution parameters of the media assets are 4K, 1080P and 720P, and the maximum supported resolution parameter of the display device is 4K. It may be determined that the resolution parameters supported by the media asset do not include the resolution parameter that is not supported by the display device, and then the resolution parameters 4K, 1080P, and 720P supported by the media asset may be determined as candidate playback quality parameters.
As an example, after determining the candidate playback quality parameters, an option for each candidate playback quality parameter may be presented in the display device. If the user wants to switch to a candidate playing quality parameter, the user can select the candidate playing quality parameter through the control device or the gesture.
As an example, after detecting the selection operation of any of the candidate quality playing parameters, the display device may send a seventh request to the server, where the seventh request may include the asset identifier and any of the selected candidate quality playing parameters. After receiving the seventh request, the server may determine, based on the media asset identifier and any selected candidate quality playing parameter, a code stream of the media asset under any candidate playing quality parameter, and since there may be code streams corresponding to multiple playing effect parameters under any candidate playing quality parameter, a code stream corresponding to a target playing effect parameter under any candidate playing quality parameter may be selected, and the selected code stream is fed back to the display device, and the display device may decode and play the obtained code stream after receiving the code stream fed back by the server.
Further, after the control corresponding to the target playing effect is displayed, the media asset can be played based on the target playing effect parameter in response to the triggering operation of the control corresponding to the target playing effect parameter.
That is to say, after the control corresponding to the target playing effect parameter is displayed, if the trigger operation on the control corresponding to the target playing effect parameter is detected, it can be considered that the user wants to play the code stream under the target playing effect parameter, and therefore, the media asset can be played based on the target playing effect parameter.
As an example, referring to fig. 8, assuming that the target playing effect parameter is a dolby view, as can be seen from fig. 8, after the trigger operation of the control corresponding to the dolby view is detected, the display device may further display an open option and a close option, if the user selects the open option through the control device, the display device may play the media asset based on the target playing effect parameter, and if the open option is in a selected state, it indicates that the picture quality of the dolby view has been successfully switched to.
Further, after the switching is completed, the display device may further display a window for prompting the user that the switching is completed.
In implementation, in response to a triggering operation on a control corresponding to a target playing effect parameter, a sixth request may be sent to the server, where the sixth request includes a media asset identifier, a current first playing quality parameter of the media asset, and the target playing effect parameter, and the sixth request is used to instruct the server to feed back a code stream of the media asset indicated by the media asset identifier under the current first playing quality parameter and the target playing effect parameter. And receiving the code stream fed back by the server and decoding and playing the received code stream.
