IBC 2014: The European Broadcasting Union (EBU) is hosting a live IP demonstration using Stagebox, a BBC R&D-developed camera mounted unit that transmits HD video and audio with genlock, timecode and tally using standard IP protocols.
Launched at last year’s NAB, Stagebox-equipped cameras can stream footage to a computer for live edits locally or at a remote location.
It has been used by the BBC for coverage of Glastonbury and the recent local elections.
Some of the benefits highlighted by Stagebox’s developers include remote operation, potentially reducing the need for outside broadcast equipment.
The IBC demonstration will show how a Cisco Nexus 3548-based network infrastructure enables Stagebox devices to deliver video, audio, tally and a remote camera control over IP.
Using the built-in hardware support for the IEEE 1588 Precision Time Protocol (PTP) in the Cisco Nexus 3548 switch, combined with the Tektronix hybrid Sync Pulse Generator / PTP Grandmaster delivering facility reference signals and ensuring a stable timing source, the demonstration uses Stagebox as a PTP slave clock to produce the same genlock functionality found in traditional live broadcast infrastructure.
Meanwhile, Trilogy Communications is showing its Gemini IP intercom system working with Stagebox.
Trilogy sales director Ewan Johnston said: “Gemini, already being an IP-based comms system, has taken a major step toward all-inclusive IP production with the successful completion of integration testing of its talkback system and Stagebox on a Cisco-based Wide Area Network (WAN).”
