But let me tell you how seriously broke this whole mess is. Too many companies wanting a piece of the royalty pie will end up ruining or seriously slowing down this whole mess. Because all the other companies were trying to prop up Zenith, who went chapter 11 and ended up a totally foreign company. Not that that is bad mind you, Zenith needed a head chopping. Zenith always had reasonably good engineering, but the management stunk, and that goes back to the early 1970's.
Lets start with component video.
First take the R,G and B signals directly from the DACS, and add and subtract them to generate Y, Pr Pb using analog opamps, degrading the signal. How about a firewire directly out of the tuner directly into the tv. Naw, thats too easy and makes sense. And why component video anyway, because its a different standard that forced people to buy another display device. If it was RGB instead you could hook it up to any SVGA display monitor.
