Digital-S (or D-9) was a professional digital video tape cassette format introduced by JVC in 1995.
The cassette shell was very similar to JVC’s VHS format, but despite this Digital-S is not compatible with the later consumer D-VHS format as the tape formulation and data format are different.
Digital-S competed with other professional formats such as DVCAM, DVCPRO and Digital Betacam, and was a commercial failure. However, it saw some use in the US, Asia, and Europe, including at the BBC.
Digital-S was given the designation D-9 by the SMPTE in 1999. A high-definition version, D-9 HD, was announced but doesn’t appear to have been launched.
D-9 doesn’t appear to have lasted much beyond the early 2000s.
