Improved version of VHS
S-VHS (スーパー・ヴィエイチエス), the common initialism for Super VHS, is an improved version of the VHS (VHS standing for video home system) standard for consumer-level video recording.[1] Victor Company of Japan introduced S-VHS in Japan in April 1987, with their JVC-branded HR-S7000 VCR, and in certain overseas markets soon afterward. By the end of 1987, the first S-VHS VCR models from other competitors included the Hitachi VT-2700A, Mitsubishi HS-423UR, Panasonic PV-S4764, RCA VPT-695HF, and Toshiba SV-950. It has been standardized as IEC 60774-3 and IEC 60774-4.[2][3]
