Problems solved by technology

Especially for TV software middleware, it is generally impossible to know when the third-party application will release the audio and video decoder, so it must wait until the third-party application completely exits before performing the channel switching action, so that the third-party application switches to DTV, HDMI and other signal sources. longer time
[0003] At present, it takes about 2.5s for a smart TV to switch between signal sources, and it takes about 4s to switch between third-party applications and DTV, HDMI and other signal sources. During the switching process, the TV is in a black screen state, which affects users. to experience

Embodiment Construction

[0038] like figure 1 As shown, it is a schematic diagram of the player structure for audio and video playback in the prior art. For a smart TV system, each signal source and third-party application will create a player player when playing audio and video. When playing audio and video, each Players need to exclusively occupy the audio decoder and video decoder, so only one player can exist at the same time. For example, when exiting to DTV from a third-party application, you need to destroy AppPlayer first and then create DtvPlayer. Since it takes a certain amount of time to exit the player, the TV will be in a black screen state during the switching process, affecting user experience.

[0039] In view of the above problems, embodiments of the present invention provide a method and device for switching audio and video applications. In the embodiment of the present invention, by setting the audio and video resource management module to manage the audio decoder and video decode...

Abstract

The invention discloses an audio and video application switching method and device. The method comprises the steps that when an instruction for switching a first audio and video application to a second audio and video application is received, an audio and video resource management module stops decoding the first audio and video application and allocates a second memory to the second audio and video application to store frame data of the second audio and video application; and in addition, the audio and video resource management module releases a first memory allocated to the first audio and video application. The time needed for switching the first audio and video application to the second audio and video application is shortened, therefore, the blank screen time in the switching process is shortened and even avoided, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of digital television, in particular to a method and device for switching audio and video applications. Background technique [0002] At present, there are many audio and video applications on smart TVs, such as signal source DTV, HDMI, etc., and third-party applications Youtube, Netflix, Amazon, etc. Users often need to switch between different audio and video applications. Since audio and video applications need to exclusively occupy the audio and video decoders when playing audio and video signals, when switching from one audio and video application to another, the previous audio and video application needs to release the audio and video decoders first , the next audio and video application can open the audio codec and video codec. Especially for TV software middleware, it is generally impossible to know when the third-party application will release the audio and video decoder, so it must wait ...
