Abstract: A method for audio/video synchronization and an apparatus thereof are provided. At least one dynamic synchronization checkpoint is disposed on the playback sample number axis of a video. Whether or not the audio and the video are synchronized is checked when the playback sample number of the video is set the dynamic synchronization checkpoint. The video is paused playing if the playback speed of the video is too fast, and those delayed playback sample number of the video having not been played are skipped if the playback speed of the video is too slow. Furthermore, the location of the dynamic synchronization checkpoint and the frequency of performing synchronization detection are adjusted according to the playback time jitter between the audio and the video.

Abstract: Disclosed is a method and apparatus for dynamically adjusting the playout delay for audio signals, which mainly includes three parts of dynamic adjustment, i.e., playout delay, silence length, and jitter buffer size. In the invention, the time for playout delay is real-time adjusted according to the probability distribution of the number of packets buffered in a jitter buffer. A voice active detection mechanism is taken to detect silence within a voice packet. By dynamically adjusting the silence length in the voice packets, the present invention reduces the network variation impact on the voice quality. It also overcomes the drawback of conventional techniques for estimating playout delay, and reduces the whole computation complexity of the playout delay for the voice packets.
