Genlock: Synchronizing Devices

Sync Generators: for Display, and More

'House sync' modules (also known as black-burst or sync generators), such as these examples, with the

required number of outputs, generate a configurable square-wave sync pulse for genlocking the sync

cards and other timing-dependent devices, such as show controllers, live capture cards, and separate

audio systems:

The smaller unit, above, can be used to provide a reference pulse simply for display synchronisation.

We commonly recommend a tri-level sync pulse of an appropriate format for the required display

resolution and refresh rate.

The larger unit also provides an audio-synchronising 'word clock'. This is a digital signal at 44.1 or 48 kHz

designed for keeping digital audio devices in sync with a constant, precisely-timed bit-rate. Since LTC is

broadcast via an audio source, a word clock will keep all devices including the LTC source in sync. A sync

generator such as this will therefore meet the needs of both GPU display sync, and server playback sync

via LTC.
