Identify the S-Video port in the image given below.
S-Video, also known as Y/C video, stands for Super-Video. It is a technology for video transmission.
Using this technology, the video is transmitted into two separate signals. One is used forcolor, and the other for brightness. Sometimes S-Video signals are considered as a type of component video signal. However, its quality is inferior to other complex component video schemes such as RGB. This technology produces sharper images than those produced by composite video, which carries the entire set of signals in a single line. For using S-Video, the device sending the signal must support SVideo output and the device receiving the signal needs to have an S-Video input jack.
