SMPTE 278M-1996 (Archived 2004)

This standard specifies the content of the data blocks which form the helical records as specified in ANSI/SMPTE 277M on 19-mm tape in cassettes as specified in ANSI/SMPTE 226M. Part of this standard is the specification of the time and control code record, which forms the longitudinal index track as specified in ANSI/SMPTE 277M. Digital video and audio data derived from various image standards are recorded with a data rate of approximately 1 Gbit/s. All image standards recorded by this format employ the identical track pattern, inner and outer block structure, and modulation code.
