Design of Audio and Video Multiplexing Based on Intellectual Property Module

Specific to audio and video data multiplexing in Broadcast and TV system, a scheme of intellectual property module based on FPGA was advanced in this paper. After introduction to the related standards, the architecture of audio and video data multiplexing IP module and design processing were introduced. Through the experimental results, it is shown that the IP module could effectively multiplex audio data to video stream and achieve audio and video synchronization. Finally, the IP module output multiplexed stream through SDI.
