| titleOfInvention | Audio channel switching method, device and system |
| abstract | The invention provides an audio channel switching method, device and system. The method includes the following steps that a request for audio channel switching is received; sending of video data to a video decoder and sending of audio channel data to an audio decoder are stopped; a stream buffering area of the audio decoder is emptied, and a frame buffering area of the audio decoder is not emptied; new audio channel data in the audio channel switching process are read from file or network streams and sent to the stream buffering area of the audio decoder. The audio channel switching method saves memory space and is relatively applicable to low-end products with low memory configuration, normal output of audios can be ensured, and the phenomenon of clamping and pausing can be avoided. Due to the fact that read new audio data can be joined with the audio channel data of the frame buffering area of the audio decoder, the phenomenon of clamping and pausing in the audio channel switching process is avoided and the phenomenon that audio output does not occur within a short time is avoided. Thus, smooth transition of audio track switching can be achieved. |
