It always surprised me that ITV didn't start using SIS on their
circuits until 1989, when they were forced to because of stereo audio
transmission. You'd have thought it would have made live far easier, as
their contribution and distribution often altered every 30 mins or so ?

Problem comes of course if you wish to treat the two signals separately at
any point - like say route the audio through a mixer to adjust levels,
etc. You need to decode then re-encode. And the equipment was expensive.
It may in the early days have been BBC only too.
