1970 BBC feature on 30 line television
 

A fascinating item here from a BBC programme shown in April 1970, looking back at the production of the first televised play in 1930. At the time of this item most of the original cast and crew were still around to re-enact it... in colour!

I'm pretty sure when 'The Man With The Flower In His Mouth' was broadcast, the procedure was to show a few minutes of vision, followed by a blank screen with the audio as both could be not be transmitted at the same time. Is that correct?

Steve
Thankyou for flagging this up I found it fascinating.

Yes it's excellent Chris, although rather sobering when you consider the 1970 recording is itself older (at 52 years) than the 40 year old broadcast they were discussing!

Hello

The first public BBC 30 line experimental television transmission took place on the 30th September 1929 using the 2LO transmitter in London.
As you suggest, as there was only one transmitter, speech and vision could not be transmitted at the same time so the sound was broadcast first for a few minutes to be followed by the vision.

However by the 31st of March 1930 the BBC twin wavelength station at Brookman's Park had opened so from that date sound and vision were normally transmitted simultaneously using the twin wavelengths.
.
The first BBC television play, "The man with a Flower in his Mouth", was broadcast on the 14th July 1930.

Yours Richard

Well worth investigating the BBC Archive channel on Youtube as they turn up some fascinating material. A new clip is added every day. I've subscribed so I don't miss anything!
