Description
technical field [0001] The application belongs to the technical field of video signal transmission, and in particular relates to a conversion circuit for converting an S-separation video signal into a composite video signal. Background technique [0002] S-separation video signal (also known as S-Video signal) is a signal that separates and transmits luminance and chrominance, which can avoid the mutual interference of luminance and chrominance during mixed video signal transmission, and is widely used in various laboratories and experiments. Video signal transmission for platforms and onboard equipment. A composite video signal is a composite signal including a luminance signal and a chrominance signal, and is widely used in acquisition and display. [0003] However, in the process of aircraft signal collection and display, due to the need to collect and monitor multiple channels of data, and the signal transmission distance is not the same. In order to ensure the transmi...
