 From the launch of the branding, live in-vision continuity was generally broadcast by a dedicated team of presenters from a small self-op Presentation studio within the BBC1 network control area at Television Centre.The presenter would talk, interact with other characters, and view children’s pictures and letters, many of which would end up on the dressed back wall of the booth.They would also operate sound and vision mixers to partially direct their own links, although overall responsibility for transmission belonged to duty transmission staff in the adjacent network control room (NC1).
