Abstract :
Television broadcasting applications sack as ATSC-M/H, DVB require that the encoded audio and video streams to be transmitted across a network in a single transport stream containing fixed sized data packets that can be easily recognized and decoded at the receiver. MPEG 2 part1 specifies two layers of packetization to achieve a transport stream suitable for digital transmission. This paper presents a scheme to multiplex the elementary streams of H.264 video and HE AAC v2 audio using the MPEG2 systems specifications, then de-multiplex the transport stream and playback the decoded elementary streams with lip synchronization or audio-video synchronization.
