Signal chain
ENG-06CAMERA
SDI 3G / 12G, camera control unit, fibre back to the OB van.
No picture: check CCU fibre, SFP levels and the base-station power. Sparkles usually mean a dirty fibre connector.
Core concepts
REF-IPSingle coax carrying video, embedded audio and ancillary data.
Separate essence flows for video, audio and metadata over IP.
