System design for broadcast and live production, multicamera signal flow, livestream architecture, sync and comms planning, and the documentation crews rely on.
Live production is systems engineering at showtime
A multicamera production is a small broadcast plant: acquisition, switching, playback, record, monitoring, comms, and transmission, all interlocked. The systems that survive live conditions share one habit, every path is drawn, every path has a backup you've actually tested.
Start with the multicamera livestream signal-flow example, a worked architecture from cameras to encoder, with the record and monitoring paths most first drawings forget. The same documentation method scales from a two-camera stream to a truck show.
Draw program, preview, record, and monitoring as separate paths, they fail separately.
Sync and timecode are system-level decisions, not per-device settings.
Comms is a signal path too: channel plans belong in the tech pack, not in someone's head.
