To be used in conjunction with Field Dominance. The DIVO-DVC option board has two GPI connectors, each associated with one of the serial digital video ports. Each port has two transmit and two receive channels. Each tick of the clock consists of a unique signal that represents a time code. The code itself occupies lines in the vertical blanking interval of each field of the video signal.
People use the user bits to store information such as reel and shot number for indexing footage.
Under certain circumstances, the original VITC recorded with footage can go along with that footage as it is edited, so that you can produce an edit list or track assets for a final prototype edit. DIVO-DVC option always extracts VITC information from the fields as they are captured and pass this information to the application as buffer information associated with the dmBuffer. Inline controls specify control changes to happen between buffers. For example, if you want to play out two video clips that have different packing formats in memory, the application would set up the path, queue the buffers from the first clip, set up inline controls to match the next clip, and queue the buffers from the second clip. In this syntax, refnode is the reference node, identifying a unique connection in a path with more than two nodes.
