Flipped RGB colours in a TV

[pbuk]

And was switching between studios preserving frame sync really ever done?
How were the signals generated by the cameras in different studios synced in the first place?

However the Central Apparatus Room was on the second floor of the 'central wedge'

Does that mean that the cables were not originally routed via the hub? I can't find hard evidence either way about what equipment was actually there. I will ask around.

I have found a document that answers all these questions about Television Centre and more: http://www.tech-ops.co.uk/tech_guide.pdf (sorry about the hijack).

In summary:

• There was indeed a central sync generator in the CAR which was fed to each studio.
• Feeds from each studio went to the CAR where switching was performed and fed to the broadcast system.
• There were separate feeds from each studio to the tele-recording suite under the central hub.

Excellent sleuthing, young man. So now we are up to date with the history of TC. Doing it 'that way round' makes a lot of sense . Everything was analogue in those days and long video delays were a lot of trouble so at least starting with good timing at each source was handy. I wonder how that layout design was arrived at (i.e. technical input). The result was a pretty iconic building which is identifiable from the air.
