Does anybody know of any recent changes to the UK Broadcast video format (terrestrial 625 line)?
I have just been doing some experiments with a video sync seperator to strip the 15.625 kHz line sync pulses (suitably filtered for flyback 1/2 lines) but I seem to be getting 15.600 kHz.
This is true for all four proper terrestrial channels (forget Channel 5 - they are all over the place - Fisher-Price video mixer desk ?).
I wondered if something was happening on the quiet to 'ease us into the digital age' or something, if the good old 625 standard was being sneaked out? A direct email to Auntie was just ignored, so no help there then!
I would be surprised if anything has happened but I can't find a better explanation for THREE frequency meters all being wrong to exactly the same degree.
