S-VHS FORMAT (IEC60B(Sec)199)
Super VHS uses higher coercivity tape in standard VHS outline cassettes together with a higher luminance carrier frequency and bandwidth. The result is improved picture definition (>400 horizontal lines), which challenges the performance of many domestic TV receivers and better signal to noise. The longitudinal and FM audio features are as normal VHS. S-VHS cassettes have an ident hole to enable S-VHS recorders to switch automatically between VHS and S-VHS standard according to the tape inserted.
