| Abstract: | 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 transmit in the same way. This technique achieves good results in practical application. |
