ST 318:1999 - SMPTE Standard - For Television and Audio — Synchronization of 59.94- or 50-Hz Related Video and Audio Systems in Analog and Digital Areas — Reference Signals

This standard specifies the use of a derivative of a color black signal as a reference for the synchronization of all forms of composite or component, digital or analog equipment using a system standard related to 59.94 Hz (60/1.001) or 50 Hz. — It also provides the option for the reference signal to carry VITC. This will allow the reference to distribute local or UTC time data. — In the case of the reference for 59.94-Hz related signals, the signal may carry optionally a ten-field sequence identification signal. This facilitates interworking with equipment operating at related rates (e.g., 23.97 Hz (24/1.001) or 48 kHz).
