Since the Prop2 can generate HDTV signals in Y/Pb/Pr component format, I thought I'd share a link to the
document covering HDTV signal generation. I offer this because it is almost impossible to find if you don't know what to ask for. I haven't tried recently, but when I started doing work to support HDTV, I could not find anything that described the signal format from many, many searches. Somehow, after much time, I discovered that what I needed to know was in "RECOMMENDATION ITU-R BT.709-3". It's all here:
I will post some Prop2 code here soon that does 1080p video generation. It just takes three pins on the Prop2 configured as DACs. The output signals are called Y (luma), Pb (blue difference), and Pr (red difference). These are typically connected via RCA (or phono) cables.
