Terry, I'll do a 405 "sound in syncs" if you're not careful
AFAIK, SIS was only done on 625 and was never broadcast. Do you know if there was ever an accident where it escaped? My only involvement with SIS was to design a SIS stripper, to get rid of SIS and produce a clean video waveform.

SIS was a brilliant invention. Saved the cost of sound circuits from the studio to the TX, made sure that sound and vision stayed together and gave improved quality compared to analogue sound circuits.
