BBC Two Shows Testcard

This morning about 5.00am BBC Two showed Testcard 7 (I think that's what it's called) Why did they do that? Normally they'd just show Ceefax. Anyway Ceefax did come on about 5.30am.

Another question, why when they show a testcard does it have those 'blips' for sound. http://web.ukonline.co.uk/tv.home/forum/emoticons/confused.gif

The funny blips are an audio test signal called GLITS (see definitions). They're used by engineers to check that what is being transmitted on the left leg is being received on the left etc. Also that both the left & right legs are not out of phase.

Hope this helps

Thanks Techy Peep. Do you know why they showed the test card instead of Ceefax. Technical problems perhaps? http://web.ukonline.co.uk/tv.home/forum/emoticons/confused.gif

Probably doing a line-up of the transmitting chain

Testcard 7? Dont you mean TCJ?

Well if it was widescreen Testcard J,if not-Testcard W. There is no such thing as testcard 7.

That's another 10 quid on its way to Carole Hersee then.....

Does she get royalties from doing that?

Mixed up Billy. 4:3- TCJ, 16:9-TCW. I miss TCF Though:( bring it back.

Is anyone able to do a capture of what the test card 7 or whatever looks like?

This is TCJ:
