The hardware or software architecture in some embodiments may be based on the description in the foregoing embodiments, and in some embodiments may be based on other similar hardware or software architectures, which may implement the technical solutions of the present application.

In some embodiments, the media provided by the video on demand APP (application) may come from a third party media platform, such as a cool, loving, messenger, etc. media platform. The video on demand APP establishes connection with a plurality of third party media resource platforms through the server, and obtains and displays the media resource on the third party media resource platforms. Some assets on the third party asset platform may be provided with multiple resolutions, such as 480p,720p,1080p, etc. The server can establish different data connection with the third party media resource platform to acquire media resources with different resolutions, when a user requests the media resources in the video-on-demand APP, the display device can select default resolution to play the media resources according to the network environment, for example, 480p is set to be the default resolution according to the network environment which is a mobile data environment, and 720p is selected to be the default resolution according to the network environment which is a WiFi environment.

In some embodiments, the user may input the resolution adjustment signal on the display device to perform resolution adjustment, change the resolution of the media asset to be higher or lower, and when the user inputs the resolution adjustment signal on the display device, the display device needs to notify the server to disconnect the current data connection and establish a new data connection, so as to obtain the media asset consistent with the resolution in the resolution adjustment signal for playing. However, since the server disconnects the data connection and reestablishes a new data connection, a certain time is required for the display device to stop playing during the time, which results in a pause or a black screen of the screen, and affects the viewing experience of the user.

In order to solve the technical problem, the application transmits the playing progress by establishing auxiliary connection between the display equipment and the server, the server updates the data channel in real time according to the playing progress, so that the data channel is abutted to media resources with different resolutions, after a user inputs a resolution adjustment signal on the display equipment, the server temporarily acquires the media resources with corresponding resolution through auxiliary connection according to the transmission playing progress and provides the media resources with new resolution for the display equipment, so that the user can acquire the media resources with new resolution in time, the resolution switching efficiency is improved, and the user watching experience is improved.

Referring to fig. 6, an interaction diagram in a resolution switching process according to some embodiments of the present application is shown. As shown in fig. 6, in some embodiments, the player may be a functional module capable of playing media resources on a controller of the display device, the client may be a functional module capable of acquiring media resources from a server on the controller of the display device for the player to play, and the video on demand APP may include the player and the client. The server may be a server, and may be capable of obtaining media assets from a third party media asset platform.

When the user opens the video on demand APP, the player of the video on demand APP is initialized, and the initialization may include checking whether the function of the player is normal, whether the hardware configuration of the display device such as the memory is normal, and the like.

After the player is initialized, a user can click on a media asset in the video-on-demand APP to generate a media asset on-demand request, wherein the media asset clicked by the user can be called a target media asset. The player sends a signal for requesting to establish connection to the client according to the media information request, the client establishes a first connection with the server according to the signal for requesting to establish connection to generate a first connection channel, wherein the server can be provided with a plurality of internal data channels, the server can respectively point the plurality of internal data channels to a plurality of resolution files of target media information on the media information platform through pointers, and then one of the internal data channels is utilized to transmit media information of the resolution files. The internal data channel for the server to transmit the media asset data may be selected according to the resolution provided by the client when requesting to establish the first connection, and when the client does not provide the resolution when requesting to establish the first connection, the server may select a default internal data channel to transmit the media asset data with the corresponding resolution.

In some embodiments, the first connection may be an http connection and the first connection channel is an http connection channel. Assuming that after the server establishes the first connection with the display device, the resolution of the transmitted media data is the first resolution, where the first resolution may be a resolution supported by any target media such as 480p,720p,1080 p.

In some embodiments, the media data sent by the server to the client may be M3U8 clips, and the M3U8 clip may be a TS clip with a playback duration of 10 seconds, where the M3U8 clip may be referred to as a first resolution media clip.

After receiving the M3U8 fragment, namely the first resolution media asset fragment, the client can control the player to play the first resolution media asset fragment, so that the user can see the target media asset with the first resolution on the video on demand APP.

After the player starts to play the target media with the first resolution, the client can establish a second connection with the server to generate a second connection channel.

In some embodiments, the second connection may be a tcp connection and the second connection channel may be a tcp connection channel. After the tcp connection channel is established, the client can acquire the playing progress of the player in real time and send the playing progress to the server. The playing progress may be index information of the first resolution media asset segment, such as the number of the 3U8 segment or the start playing time corresponding to the M3U8 segment.

After receiving the playing progress, the server can point the current internal data channel to a plurality of media resource fragments with different resolutions corresponding to the playing progress in real time.

When a user views a target asset of a first resolution on a video on demand APP, if the user is not satisfied with the first resolution, the resolution can be switched on a display device, and a resolution switching request is generated. The player transmits the resolution switching request to the client, and the client sends the resolution switching request to the server through the second connecting channel, so that the tcp synchronous switching state is realized.

The server obtains a second resolution real-time fragment of the target media asset, wherein the second resolution real-time fragment is a second resolution media asset fragment corresponding to the playing progress, and returns the second resolution real-time fragment to the client through a second connecting channel, and the second resolution real-time fragment is also an M3U8 fragment. Before the resolution switching request is received, one data channel of the server points to the real-time media resource fragments with different resolutions in advance, so that the server can quickly acquire the real-time fragments with the second resolution in a short time, and the server sends the real-time fragments with the second resolution to the client through the established second connection channel, thereby ensuring the sending efficiency.

And after receiving the second resolution real-time fragment, the client controls the player to immediately play the second resolution real-time fragment. Because the speed of the server for acquiring the second resolution real-time fragment and the speed of the server for transmitting the second resolution real-time fragment are both very fast, the second resolution media fragment can be played in a shorter time after the resolution is switched by the display device, and the user can hardly feel that the picture of the display device is black or paused, thereby realizing seamless switching play and improving the user experience.

Further, the client disconnects the first connection with the server, establishes a new first connection with the server, and generates a new first connection channel.

After the new first connection channel is established, the client switches channels, namely, channels for acquiring media data are switched from the second connection channel to the updated first connection channel, and then media fragments after the real-time fragments with the second resolution are pre-downloaded.

After the player plays the real-time fragment with the second resolution, the client sends the pre-downloaded media fragment to the player for playing, and then continues to download the subsequent media fragment with the second resolution. Because the client downloads the second resolution media asset fragment after the second resolution real-time fragment is pre-downloaded when the player plays the second resolution real-time fragment, after the second resolution real-time fragment is played, the player can play the second resolution media asset fragment after the second resolution real-time fragment is played in time, and the playing fluency of the target media asset of the second resolution is ensured.

Further, the client may further send the playing progress to the server through the second connection channel, so that the server may update the pointer of the internal data channel.

Referring to fig. 7, a schematic diagram of a server data channel according to some embodiments is shown. As shown in fig. 7, the data channel pointer of the server includes a pointer 1, a pointer 2, and a pointer 3, wherein the pointer 1 points to M3U8 slice data 1 of resolution 1, the pointer 2 points to M3U8 slice data 1 of resolution 2, and the pointer 3 points to M3U8 slice data 1 of resolution N. Resolution 1 may be 480p, resolution 2 may be 720p, and resolution N may be 1080p.

After the current playing fragment changes, the data channel pointer of the server points to the latest current playing fragment again, for example, when the current playing fragment is updated to MSU8 slicing data N, pointer 1 points to M3U8 slicing data N of resolution 1 again, pointer 2 points to M3U8 slicing data N of resolution 2, and pointer 3 points to M3U8 slicing data N of resolution N.

To further explain the above resolution switching process, the embodiment of the present application further provides a method for rapidly switching resolution, which is used for a display device, referring to fig. 8, and the method may include the following steps:

step S110: and responding to the received media request input by the user, establishing a first connection channel with the server, acquiring media fragments with first resolution through the first connection channel, and controlling the display to play the media fragments with the first resolution.

In some embodiments, the media asset on-demand request is generated after the user clicks on a target media asset on the video-on-demand APP of the display device. The controller of the display device establishes a first connection channel with the server according to the media request, receives the media fragment with the first resolution sent by the server through the first connection channel, and controls the display to play the media fragment with the first resolution.

For example, the first connection channel may be an http connection channel, the first resolution is any resolution supported by target media resources such as 480p, 720p, 1080p, etc., for example, the media resource segments of the first resolution are M3U8 segments, and each M3U8 segment may be a TS segment with a play duration of 10 seconds.

Step S120: and establishing a second connection channel with the server, acquiring the media asset playing progress of the display, and sending the media asset playing progress to the server through the second connection channel.

In some embodiments, the display device establishes a second connection channel with the server after the video on demand APP begins playing the media break of the first resolution of the target media. The display equipment obtains the media resource playing progress of the first resolution media resource fragment played in real time by the video on demand APP, and sends the media resource playing progress to the server.

For example, the second connection channel may be a tcp connection channel, and the media playing progress may be index information of the media clips, such as the number of the M3U8 clip or the start playing time corresponding to the M3U8 clip. For example, at time t1, the time corresponding to the media clips of the first resolution played in real time according to the video on demand APP is 03:00-03:10, namely, the content from the 3 rd minute to the 3 rd minute for 10 seconds, acquiring the index information of the content to be 03:00, and sending the index information to a server; at time t2, the corresponding time of the media resource fragment of the first resolution played in real time according to the video on demand APP is 03:10-03:20, namely, the content from the 3 rd minute 10 second to the 3 rd minute 20 second, acquires the index information of the content to be 03:10, and sends the index information to the server.

Step S130: and responding to the resolution switching request input by a user, acquiring a real-time fragment with a second resolution corresponding to the playing progress through the second connecting channel, and controlling the display to play the real-time fragment with the second resolution, wherein the second resolution corresponds to the resolution switching request.

In some embodiments, after the user adjusts the resolution on the video on demand APP, a resolution switch request is generated, which the display device sends to the server through the second connection channel.

The display device receives the second resolution real-time fragment from the server through the second connecting channel, controls the display to play the second resolution real-time fragment, and realizes seamless connection of the first resolution media resource fragment and the second resolution real-time fragment.

For example, at time t2, when the user adjusts the resolution of the target asset from 720p to 1080p, the display device sends a resolution switching request containing 1080p to the server through the tcp connection channel. According to the latest index information of 03:10, the server sends 1080p target assets of 03:10-03:20 as second resolution real-time fragments to the display equipment, and the display equipment switches the 720p target assets of the previously played 03:10-03:20 into 1080p target assets of 03:10-03:20.

Step S140: updating the first connection channel, and acquiring the media resource fragment with the second resolution after the playing progress through the updated first connection channel.

In some embodiments, the display device disconnects the first connection with the server, establishes a new first connection with the server, and obtains the target media asset of the second resolution through the new first connection when playing the real-time clip of the second resolution.

For example, when the display device plays 1080p target media of 03:10-03:20, a new http connection channel is established according to the display device and the server, the data receiving channel of the display device is switched to the new http connection channel, and 1080p target media after 03:20 is pre-downloaded through the new http connection channel.

Step S150: and controlling the display to play the media asset fragments with the second resolution after the playing progress according to the completion of the playing of the real-time fragments with the second resolution.

In some embodiments, the server sends the second resolution media asset segment subsequent to the second resolution real-time segment to the display device. After playing the second resolution real-time segment, the display device plays the second resolution media asset segment after the second resolution real-time segment.

For example, after receiving 1080p target assets of 03:10-03:20 of tcp channel, 1080p target assets after 03:20 are played.

Further, the display device may further obtain a media playback progress of the display, and send the media playback progress to the server through the second connection channel.

Corresponding to fig. 8, the embodiment of the present application further provides a resolution fast switching method, which is used for a server, and referring to fig. 9, the method may include the following steps:

step S210: and establishing a first connection channel with the display equipment, acquiring a media resource fragment with a first resolution, and sending the media resource fragment with the first resolution to the display equipment through the first connection channel.

In some embodiments, the server establishes a first connection channel with the display device according to a first connection establishment request of the display device, obtains a first resolution media asset fragment of the target media asset, and sends the first resolution media asset fragment to the display device through the first connection channel.

For example, after establishing an http connection channel with the display device, the server acquires the 720p media asset fragment of the target media asset, and sends the 720p media asset fragment to the display device for playing by the display device.

Step S220: and establishing a second connection channel with the display equipment, and acquiring the media playing progress of the display equipment through the second connection channel.

In some embodiments, the server establishes a second connection channel with the display device according to the second connection channel establishment request of the display device, and receives index information sent by the display device through the second connection channel.

Step S230: and setting the internal data channels of the server to respectively point to media clips with different resolutions corresponding to the media playing progress according to the media playing progress.

In some embodiments, the server continuously perceives the media clips played by the display device in real time according to the index information sent by the display device, and directs the internal data channels to the media clips with different resolutions corresponding to the index information to form a one-to-many relationship.

For example, the server points the data channel to the 480p media resource segments of 03:00-03:10, the 720p media resource segments of 03:00-03:10 and the 1080p media resource segments of 03:00-03:10 according to the index information of 03:00; according to the index information of 03:10, pointing the data channel to 480p media resource fragments of 03:10-03:20, 720p media resource fragments of 03:10-03:20 and 1080p media resource fragments of 03:10-03:20.

Step S240: and according to the received resolution switching request of the display equipment, acquiring a real-time fragment with a second resolution corresponding to the media playing progress through the internal data channel, and sending the real-time fragment with the second resolution to the display equipment through the second connecting channel.

In some embodiments, the server receives the resolution switch request through a second connection channel, obtains a second resolution real-time fragment corresponding to the resolution request, and sends the second resolution real-time fragment corresponding to the index information to the display device through the second connection channel.

For example, after receiving the resolution switching request, the server sends 1080p media clips of 03:10-03:20 to the display device through a tcp connection channel according to the latest index information of 03:10 and the second resolution of 1080p in the resolution request.

Step S250: updating the first connection channel, and sending the second resolution media clips after the second resolution real-time clips to the display device through the updated first connection channel.

In some embodiments, the server establishes a new first connection with the display device in response to a request for the display device to establish the new first connection, and sends a second resolution media asset segment subsequent to the second resolution real-time segment to the display device over the new first connection.

For example, after a new http connection channel is established between the server and the display device, 1080p media resource fragments after 03:20 are sent to the display device through the new http connection channel, so that the display device can play 1080p media resource fragments after 03:10-03:20 are played.

The present embodiments also provide a server that may be configured to perform the methods described in steps S210-S250.

As can be seen from the foregoing embodiments, in the embodiments of the present application, after a first connection channel is established with a server to transmit media data, a playing progress of a display device is transmitted to the server in real time by establishing a second connection channel with the server, so that the server points an internal data channel to media data with different resolutions of the same progress in real time according to the playing progress, after a user switches resolutions, media data with updated resolutions can be temporarily provided for the display device through the second connection channel, after a new first connection is established between the display device and the server, media data with updated resolutions is provided for the display device through the new first connection, thereby solving the problem that the display device needs to wait for the media data with the first connection of the display device for a long time, so that a black screen or a screen is blocked on the display device, and improving viewing experience of the user.
