Digital-S (or D-9) was a professional digital video tape cassette format introduced by JVC in 1995.
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.
