S-VHS
Super VHS, commonly abbreviated as S-VHS, is an analog video cassette format introduced by JVC in 1987 as a more developed version of the VHS (Video Home System) format. S-VHS improved image quality by increasing the bandwidth of the luminance (brightness) signal, allowing for a resolution of approximately 400 horizontal lines, compared to the 240 lines typical of VHS. The format used the same physical cassette shell as VHS but required higher-grade magnetic tape and compatible recording and playback equipment.
