IP to the Camera - Completing the Broadcast Chain

Extending studio data networks to cameras located anywhere around the globe is the logical endpoint of work currently underway to develop standards for future studios. Not only does this reduce the number of signal formats that need to be supported, but also enables significant cost savings by reducing or eliminating the need to deploy people and equipment to remote venues for live productions. Mobile production and ENG teams can reduce or eliminate their dependency on mobile production trucks. This paper will describe technical details of the Stagebox system developed by BBC R&D including: – Multicamera video and audio synchronization enabled by IEEE 1588 PTP – Video and audio encapsulation – Support for ancillary services including timecode, talkback, tally, and camera control – Direct integration into live workflows, including editing, archiving, and live-to-air production – Direct Deployment on the camera back with battery power — This paper will describe several live events around the globe that have already been successfully produced using this system, including “lessons learned” along the way.
