S-VHS - Computer Definition
(Super-VHS) A VHS recording and playback system that increased resolution from 240 to 400 lines and used a higher-quality cassette. S-VHS introduced the S-video interface, which separated the luma from the color (see S-video). Introduced in the mid-1980s, there is little noticeable difference between VHS and S-VHS when taping programs off-the-air. However, if the source material is higher quality (camcorder, satellite, etc.), S-VHS recordings are visibly superior. S-VHS VCRs also play regular VHS tapes, and S-VHS-ET (Expansion Technology) machines are able to record S-VHS content on regular VHS tapes. See D9.
