This paper proposes a new method for multiplexing — demultiplexing of AVS video and AAC audio stream that uses frame numbers as time stamps for achieving lip synchronization during playback. The packetization layers adopted for multiplexing the video and audio streams before their transmission conform to the MPEG-2 systems framework.
In this paper, an efficient multiplexing/demultiplexing scheme while achieving lip synchronization after decoding and playback of video and audio is presented. This has been achieved using MPEG-2 transport streams. Dirac video and AAC audio codecs have been used for compression.
