As the processing and transmitting of the video and audio signal in different ways

the video and audio signals have different delay time

and the sound and image are asynchronous. In order to solve the problem effectively mentioned above

a video-audio signal conversion system based FPGA is proposed in this paper

in which main circuits

control circuits and the peripheral I/O interface are disigned

and software is adopted to embed the digital video signals into SDI audio signal

so the video and audio can trans...
