What is the function of frame synchronizing bit in a T 1 digital system?
Frame synchronization is necessary to identify the timeslots within each 24-channel frame. Synchronization takes place by allocating a framing, or 193rd, bit. This results in 8 kbit/s of framing data, for each DS1.
Do I need genlock?
Why use genlock? In terms of avoiding drift and providing syncing points for postproduction, wireless timecode is a great tool, but if you want really accurate synchronisation for long takes and all day shooting, it's important to also genlock the cameras to a common sync source.
