Re: How the Sony non-PAL decoder works
A jolly good explanation, thank you.
I worked at Mitsubishi during the years when they used the same method. I believe we had a cross-patent with Sony on this. Teleton also had a clever non-PAL method but I never fully understood it.
The interesting feature of using Bruch blanking for ident is that a little while after the sets were on the market, Ampex developed a disk recorder for instant sports replays and slo-mos. When the broadcaster plays the the slo-mo, the frames are out of order which creates ident havoc.
If the hue/tint control is not central the hue correction switches from side to side during the slo-mo, causing a disturbing effect.
