Timing and Synchronization in a Multi-Standard, Multi-Format Facility
Successful creation, transmission, and recovery of a video picture depends on each of the devices in the system (e.g. cameras, VTRs, editors, switchers, and other video equipment) operating in synchronization with every other device. Inside a large studio or post-production plant, a master Sync Pulse Generator (SPG) provides synchronization signals. Equipment that is synchronized by a master generator is often referred to as being generator locked, or "genlocked" for short. |
