All-in-Wonder Pro/128 architecture

    There is very little technical info on the earlier All-in-Wonder architecture.
    I know there is info on the Rage chipset, and I have the Bt829 manual.
    However, there must be lots of custom logic.

    I assume there is parallel bus on the Rage for the extra devices. The 128
    seems to have mpeg hardware that the Pro doesn't.

    Since both use the Bt829, why does the 128 capture at higher resolution?

    YUV9/12/16 seem to be ATI terms. What do they mean?

    Were does the audio signal come from on the video out cables?

    Were does the audio on the video in cables go to, an on-board ADC? I assume
    that is what the TV audio device is for, which adds a video slider to Volume
    Control.

    I have to make a video-out cable for my Pro, and don't want to waste effort.
    Apparently the card can tell if TV is hooked up, how is this possible?

    Good paper, terrible scanning.

    Do I have this right? With 8-bit sampling, 4:2:2 is YUV16 and 4:2:0 is YUV12.
    With 6 bit sampling 4:2:0 is YUV9, and looks like crap?

    Do all the popular distribution formats (Mpeg-*, Windows Media) use 8-bit (or
    less) sampling?

    The ati card can sense a load on the cabling and this is how it can tell if a
    tv or video device like a vcr is hooked up

    Why build a cable when you can get one for cheap many places like here?
