摘要： Systems and methods of adjusting synchronization of audio media streams and video media streams in 3G mobile communications systems that can mitigate the effects of temporal skew due to intervening processing elements associated with media channels carrying the respective media streams. The systems and methods are operative to adjust the synchronization of audio media streams and video media streams by receiving control messages that report delays due to such intervening processing elements, calculating a relative amount of delay using the reported delays for each media channel, and applying a delay factor based on the relative amount of delay to the faster media channel to place the audio media streams and the video media streams in proper temporal alignment. The delay factor is applied to the faster media channel at those locations within the mobile communications systems where the audio and video media streams are combined and/or separated for subsequent transmission.
