Timing Sources

What this does not do, is synchronise a non-Delta LTC player with any other device. So if an LTC source is

used that is not genlocked, then the LTC player system clock will inevitably drift from that of the Delta

server(s). Over shorter play durations this should not matter, but for longer shows, the drift more will

eventually become apparent.

Genlocking

Frame synchronisation, therefore, may not be enough. The many independent clock devices in items of

digital equipment, accurate as they may be, can disagree about the precise length of a unit of time, and

drift apart. However, by giving them all the same 'pacemaker', in the form of genlocking, they can all be

kept in precise clock sync.

In this diagram, all the hardware systems are genlocked, and all servers are playing in sync with a

common LTC, which is itself genlocked.

Note that display devices also carry different degrees of latency, and this will depend also on how much

internal processing they have.
