and did L-R channel swap if the fade/pan warble tone was on the wrong leg - and could add Apology etc ... the ITC said you had to have one! .....
It was not only made to work AES3 for ITV and Embedded Audio (for BBC and others) and had a Broadcasters Mix output (for DSAT)
but also could take AD audio in and a Footswitch plus fade/pan? byte to do Live AD for itv
It was a 1 U box made by MRG Systems (better known for clever Teletext)
But I dont think the Live feature was in the Card based version done years later by AXON
The BBC view was that Live AD was too complex - but work was done to get major event Comentators aware of those that would benefit from AD and be a bit more descriptive - something the general audience found useful (by Audience research not quite focus groups!) Or to look for a Red button Alternative
- at the same time we got EastEnders and others programmes aware that you need a gap to drop the AD in "so don't do wall to wall dialogue"
