I love the little "boop boop BEEP" tune during the test card, although I can see how it would be disconcerting if you weren't expecting it. Also I had no idea they did a 3D test card, too bad George Hersee didn't use a stereo camera to photograph her daughter back in the day.

@@leannewalker539 thats because bbc are tying to shut the bbc hd channel And mostly use test card F (the screen with the loud beeps on 7:45 )is used to be mostly used when BBC'S channels are off air or no longer Avalable thats why
The different tones are testing stereo and surround sound audio. If you notice at the beginning you'll see it indicates this by flashing up "L" (Left), "R" (Right) "C" (Centre) "LFE" = ?? Possibly the subwoofer section of Surround sound and then "Ls" & "Rs" = Left & Right rear speakers.
These idents feel like the type of idents sky would use...don't understand why they don't make the BBC ONE AND BBC TWO current idents feel this premium...
That's kind of the point. The testcard tone was there to test speakers, so by alternating the tone between left and right (later adapted for Dolby Surround) you could identify which speakers, or indeed which ears, weren't working.
It does exactly what it says it does - allowing the viewer, or more specifically, the engineer, to see whether the audio and video have drifted out of synchronisation.
The Video/Audio Late card can sometimes be seen on BBC Two during the early hours of the morning right before the channel resumes normal operations, I've seen it on there before
@@oscarcookies4870 There's actually a slightly modified version of this that is in current use, without the 5.1 audio test and the BBC HD logo is replaced with just the BBC logo (and text saying HD). Saw it recently when BBC Three relaunched.
Not sure which year(s), but my guess is it would have been used internally at the BBC since the days of the development of widescreen, so mid-late 1990s. But you can Google all this, right?
