This standard specifies a digital time and control code for use in television, film, andaccompanying audio systems operating at nominal rate of 60, 59.94, 50, 30, 29.97, 25, 24 and23.98 frames per second. This standard specifies a time address, binary groups, and flag bitstructure. In addition, the standard specifies a binary group flag assignment, a linear time codetransport, and a vertical interval time code transport.This standard defines primary data transport structures for linear time code (LTC) and verticalinterval time code (VITC). This standard specifies the LTC modulation and timing for all videoformats. This standard also defines the VITC modulat
