MUSC 566: Video Sync Setup

Time Base

The Video Sync generator is the time base (speed) master. It is hard wired to the video sync inputs of the Digital Time Piece and the VTR. The DTP creates the video-referenced word clock which you will patch to the DM-4800 console. The Word Clock out of the DM-4800 is normalled to the Digidesign 192 I/O (ProTools).

Address Base

The Digital Time Piece is address base (location) master. It drags the VTR around via 9-pin remote control. ProTools chases MIDI Time Code (MTC) by being put online.
