The framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system and obtain the services of the system in execution through the API interface.

At present, when playing a video, an Android system generally undergoes operations such as player initialization, video path setting, video file information analysis, player start playing and the like. If switching to (i.e. playing) the next video is to be performed, the current video playing is stopped, and then the operations of setting the video path, parsing the video file information, starting playing and the like are performed. The whole process consumes relatively long time, and in the process of stopping the current video playing, the phenomenon of screen blacking can occur on a television product, so that the user experience is poor.

Referring to fig. 5A, a schematic flow chart of playing a next video in the prior art is shown. Firstly stopping playing the current video, then setting the next video address, preparing to play and acquiring media information, then initializing a decoder and configuring the decoder, and finally starting playing the next video by the player. For the operation of stopping playing of the current video, the schematic flow diagram of stopping playing of the player shown in fig. 5B can be referred to.

Specifically, the downloading and the protocol parsing (i.e. the downloading and the protocol parsing operation of the current video by the downloading and the protocol parsing module in the player) are stopped first, the demultiplexing (i.e. the demultiplexing operation of the current video by the demultiplexing module in the player) is stopped, the decoding (i.e. the decoding operation of the current video by the decoder in the player) is stopped, then the decoder is released, and then other resources of the player are released. Different applications may have slight differences in the above logic implementation, but there are processes of stopping the protocol parsing module, stopping the demultiplexing module, and releasing the decoder. However, the process of releasing the decoder, and initializing the decoder and configuring it again in fig. 5A, may cause a short black screen on some platforms. In addition, the process of preparing to play in fig. 5A requires re-downloading the video played for the second time, and the stopping operation of each module of the player is required to stop the current video playing in fig. 5B, both are serial, which will consume a certain amount of time, and therefore, the whole process also consumes a long time.

Therefore, in order to solve the above problems, the technical idea of the present application is to change the processing logic of the player from serial to parallel processing by the controller when switching the film sources, that is, the foreground decodes and displays the first film source, but the background has downloaded and parsed the second film source, but the decoder does not stop, and the current buffer data of the decoder is cleared and the data of the next film source is sent to decode and display, that is, the next film source is played, until the demultiplexing module takes the data of the next film source. The scheme that the next video can be played without stopping the current player is achieved, the playing speed of the next video is accelerated, seamless switching between the two videos can be achieved, and user experience is improved.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

As shown in fig. 1 to 4, the present application provides a display device including: a display;

a controller configured to:

responding to a trigger operation for requesting video switching, and maintaining the operation of decoding and displaying the current video film source on the display while downloading and analyzing the protocol of the next video film source requesting video switching;

and playing the next video film source according to the demultiplexed data.

In this embodiment, the display device is a television device, and a user may use a remote controller or an intelligent terminal (for example, a smart phone) to control the television device to play a next video (where, a video is a video source), or the television device may automatically switch to the next video when a current video is about to be played. When the next video needs to be played, the television equipment receives an instruction for indicating the playing of the next video and then informs the player to start processing.

Specifically, after receiving a trigger operation for requesting video switching, a controller in the television equipment starts downloading and protocol parsing of a next video film source, reads data of the next video film source, and simultaneously, does not stop a decoder from decoding a current video, thereby ensuring that the current video continues to be played.

In practical application, when the film sources are switched, the processing logic of the installed player is changed from serial to parallel processing through the controller, namely, the foreground decodes and displays the first film source, but the background downloads and analyzes the second film source.

And after reading the data of the next video film source, demultiplexing the next video film source through the demultiplexing module to obtain the demultiplexed data. The multiplexing/demultiplexing technology here is to collect data on multiple transport connections to one network connection for transmission, so that a network with high throughput, high rate, low transmission delay, and high cost can support the requirement of low transmission cost for users. The purpose is to separate different audio and video streams from an audio and video signal source; in addition, demultiplexing generally belongs to an active operation, namely, the demultiplexing is taken out from an audio and video signal source.

And after the data after demultiplexing is obtained, stopping decoding and displaying the current video film source, and further seamlessly switching to the next video.

The de-multiplexing module de-multiplexes the next video film source to obtain de-multiplexed data, and the subtitle output module, the video output module and the audio output module are used for outputting subtitles, videos and audios so as to play the next video film source.

The display device provided by the embodiment comprises a display and a controller, and the controller responds to a trigger operation for requesting video switching, downloads and analyzes a next video film source requesting video switching, keeps the operation of decoding and displaying the current video film source on the display, realizes the parallel processing logic of continuously playing the current video film source and simultaneously downloading and analyzing the next video film source by a protocol, does not need to stop a current player, then demultiplexes the next video film source to obtain demultiplexed data, stops decoding and displaying the current video film source, plays the next video film source, realizes seamless switching between two videos, and can play the next video without stopping the current player, so that the playing speed of the next video is accelerated.

In some embodiments, the controller is specifically configured to:

determining the address of the next video film source in response to a trigger operation for requesting video switching;

In this embodiment, after receiving a trigger operation for requesting video switching, the controller first determines an address of a next video source, then downloads and analyzes a protocol of the next video source based on the preset address of the next video source, reads data of the next video source, and simultaneously does not stop a decoder from decoding a current video, thereby ensuring that the current video continues to be played.

In this embodiment, the downloading and protocol analyzing and demultiplexing module in the controller and the decoding module are asynchronously processed. When playing the next video source, the downloading and protocol parsing module and the demultiplexing module stop operating the current video source (i.e. the current video source), release the relevant resources, and then download and parse the next video source (i.e. the next video source), but the decoder does not stop, i.e. continue playing the current video source.

In some embodiments, the controller is further configured to:

before downloading and analyzing the next video film source which requests video switching, controlling the downloading and protocol analyzing module to stop operating the current video film source and releasing the resource of the protocol analyzing module;

In this embodiment, after receiving a trigger operation for requesting video switching, the controller first determines an address of a next video source, and at the same time, the player in the controller automatically stops the download and protocol parsing module and releases resources, stops the demultiplexing module and releases resources, and does not stop the operation of the decoder. Then the next film source is downloaded and parsed.

Therefore, the downloading and protocol analyzing module, the demultiplexing module and the decoding module (namely a decoder) are asynchronously processed, so that the time in the whole video switching process is saved, and the time consumption is low.

In some embodiments, the controller is specifically configured to:

and after determining that the demultiplexed data is obtained, clearing the current buffer of the decoder to stop decoding and displaying the current video film source.

In this embodiment, after downloading and protocol parsing a next film source, the demultiplexing module is initialized, so that the demultiplexing module demultiplexes the next film source until the demultiplexing module takes data of the next film source, that is, demultiplexed data, and then the current buffer of the decoder is cleared, that is, the decoding operation of the current video is stopped.

In some embodiments, the controller is further specifically configured to:

In this embodiment, after the demultiplexing module takes the data of the next slice source, the data of the next slice source is sent to the decoder, and the decoder decodes and displays the data of the next slice source.

Fig. 6 is a flowchart illustrating a video switching method according to an embodiment of the present application. As shown in fig. 6, the method may include:

s601: and responding to the triggering operation for requesting the video switching, downloading and analyzing the protocol of the next video film source requesting the video switching, and simultaneously keeping the operation of decoding and displaying the current video film source.

In the following, a television device with a player is taken as an example, and how to implement seamless switching between videos on the television device is described in detail.

In this embodiment, a user may use a remote controller or an intelligent terminal (e.g., a smart phone) to control the television apparatus to play a next video (where the video is a video source), or the television apparatus may automatically switch to the next video when the current video is about to be played. When the next video needs to be played, the television equipment receives an instruction for indicating the playing of the next video and then informs the player to start processing.

Specifically, after receiving a trigger operation for requesting video switching, the television device starts downloading and protocol parsing of a next video source, reads data of the next video source, and simultaneously does not stop a decoder from decoding a current video, thereby ensuring that the current video continues to be played.

In practical application, when a film source is switched, the processing logic of the player is changed from serial to parallel processing, namely, a foreground decodes and displays a first film source, but a background downloads and analyzes a second film source.

Therefore, the application provides a video switching method, when switching the film source, the processing logic of the player is changed from serial to parallel processing, and the next film source is downloaded and analyzed, and the decoder does not stop, until the demultiplexing module takes the data of the next film source, the current cache data of the decoder is emptied, and the data of the next film source is sent to be decoded and displayed, the current player does not need to be stopped, the next video can be played, the playing speed of the next video is accelerated, and the decoder used by the current player does not need to be released, so that the black screen phenomenon can not occur on a television product, the seamless switching between two videos can be realized, and the user experience is improved.

In some embodiments, the present embodiment describes S601 in detail on the basis of the above embodiments. The operation of downloading and parsing the next video film source requesting video switching while maintaining decoding and displaying of the current video film source in response to the triggering operation for requesting video switching can be realized by the following steps:

step a1, responding to a trigger operation for requesting video switching, and determining the address of the next video film source.

And a2, according to the address of the next video film source, downloading and analyzing the next video film source, and simultaneously keeping the operation of decoding and displaying the current video film source.

In this embodiment, after receiving a trigger operation for requesting video switching, the television device first determines an address of a next video source, then downloads and analyzes a protocol of the next video source based on the preset address of the next video source, reads data of the next video source, and simultaneously does not stop a decoder from decoding a current video, thereby ensuring that the current video continues to be played.

In some embodiments, before downloading and parsing the next video source, it is also necessary to stop the operation of some modules in the player on the current video to release the resources and re-enable the operation of these modules on the next video. Wherein, the player can include: download and protocol analysis module, demultiplexing module and decoder. In this embodiment, a video switching method is described in detail based on the above embodiments. The video switching method can also be realized by the following steps:

and carrying out asynchronous processing on the downloading and protocol analyzing operation of the downloading and protocol analyzing module, the demultiplexing operation of the demultiplexing module and the decoding operation of the decoder.

Specifically, the downloading and protocol analyzing and demultiplexing module and the decoding module are processed asynchronously. When playing the next film source, the downloading and protocol analyzing module and the demultiplexing module stop the operation on the current film source (namely the current video film source) and release the relevant resources, and then download and analyze the next film source (namely the next video film source), but the decoder does not stop, namely, the current video film source is continuously played.

In some embodiments, how asynchronous processing is implemented may be implemented by:

b1, before downloading and analyzing the next video source requesting video switching, controlling the downloading and protocol analyzing module to stop operating the current video source and releasing the resource of the protocol analyzing module.

And b2, controlling the demultiplexing module to stop operating the current video film source and releasing the resources of the demultiplexing module.

In this embodiment, after receiving a trigger operation for requesting video switching, the television device first determines an address of a next video source, and at the same time, a player in the television device automatically stops the downloading and protocol parsing module and releases resources, stops the demultiplexing module and releases resources, and does not stop the operation of the decoder. Then the next film source is downloaded and parsed.

In some embodiments, the present embodiment provides a detailed description of S602 on the basis of the above embodiments. The demultiplexing is performed on the next video film source to obtain demultiplexed data, and the decoding and displaying of the current video film source are stopped, which can be implemented through the following steps:

step c1, initializing the demultiplexing module, and demultiplexing the next video film source to obtain demultiplexed data.

And c2, after the data after demultiplexing is determined to be obtained, clearing the current buffer of the decoder to stop decoding and displaying the current video film source.

In this embodiment, after downloading and protocol parsing the next film source, the demultiplexing module is initialized, so that the demultiplexing module demultiplexes the next film source until the demultiplexing module takes the data of the next film source, that is, the demultiplexed data, and then the current buffer of the decoder is cleared, that is, the decoding operation of the current video is stopped.

In some embodiments, the present embodiment describes in detail S603 on the basis of the foregoing embodiments. The playing of the next video source according to the demultiplexed data can be implemented by the following steps:

In this embodiment, after the demultiplexing module takes the data of the next film source, the data of the next film source is sent to the decoder, and the decoder decodes and displays the data of the next film source.

Specifically, referring to fig. 9, fig. 9 is a schematic flowchart of a video switching method according to still another embodiment of the present application.

And then downloading and protocol analyzing the next film source, initializing the demultiplexing module, demultiplexing the next film source by the demultiplexing module until the data of the next film source is taken by the demultiplexing module, clearing the current cache of the decoder, and sending the data of the next film source to the decoder for decoding and displaying.

According to the method and the device, the operation of decoding and displaying the current video film source is kept while the next video film source requesting video switching is downloaded and the protocol is analyzed in response to the triggering operation for requesting video switching, so that the current video film source is continuously played, the parallel processing logic of the next video film source is downloaded and analyzed simultaneously, the current player does not need to be stopped, then the next video film source is demultiplexed to obtain demultiplexed data, decoding and displaying of the current video film source are stopped, the next video film source is played, seamless switching between two videos is achieved, the next video can be played without stopping the current player, the playing speed of the next video is accelerated, and therefore the problems that the time consumption of the process of switching the videos in the prior art is relatively long, and in the process of stopping playing the current video, due to the fact that a decoder used by the current player needs to be released, a black screen phenomenon exists on a television product are solved, and user experience is improved.
