Design of audio demultiplexing intellectual property module based on SDI

Specific to serial digital interface (SDI), this paper advanced a scheme of audio demultiplexing intellectual property module based on FPGA. After explaining the related standard protocols, the kernel architecture of audio demultiplexing IP module and design processing were introduced in detail. Finally, this paper gives an application of audio demultiplexing system based on IP module in SDI. It is shown through the experimental results that the scheme of audio demultiplexing IP module could effectively demultiplex audio data from SDI data stream and achieve synchronization of audio and video.
