    Also referred to as house or video sync. Derived from video editing where video decks and cameras needed to proceed from one frame to other with absolute synchronization, the term is now finding use amongst audio professionals as they find the need for their digital workstations to lock to picture when working on film or video projects. A black burst generator simply outputs a video signal with no picture content. All the equipment that need synchronization is connected to this generator, and since they are all receiving the same clock signal, they remain locked to each other. Not to be confused with SMPTE time code, which is used for positional reference.
