Fire & Safety
In the event of a fire, the evacuation siren, which is a continuous sound, will be
activated
You should proceed to the nearest fire exit and assemble on Covent Garden Piazza,
opposite the main entrance of the Museum where you will be directed by London
Transport Museum staff
From foyer exit via main museum entrance
From theatre, exit front right

• Interface redundancy at source and destination
• Stream sent along two independent paths
• Seamless switching in case of failure in one transport path
• No impact on output video signal path

Looking to the future of media contribution
• Evolution of broadcast campus to IP• Increase in Remote production requirements• Higher spatial & temporal resolutions• Coupling of Real-Time & Non-Real-Time• More direct end-user control – inc. API• On-demand connectivity – inc. NRT (& charge)• ‘SDN’ for flexibility, speed & cost• IP handoff between organisations• High availability (with low latency) – NG
