Is that what you really want? A video decoder? Not a graphics card?
The current situation is that a user must purchase a high end video card
suitable for serious game or 3D CAD usage to get h.264 HiP 1080p/30. A
market niche, therefore, exists for a video card that *can* decode video
and which provides basic 2D & 3D acceleration for normal GUI based apps.
If we build a card based on a set-top box chip/media processor chip,
this is what we will have -- video decode with basic graphics.
If you want a graphics card, I think what you'll need is some
combination of a processing element (some processor) and a small FPGA
to send the video data. Most likely, you'll want a DSP with a bus
on it for memory, not a built-in memory controller, because we'd most
likely want to do the memory through the FPGA so that we have enough
bandwidth for video.
IIRC, some DSPs allow external access to the memory bus or we could use
the DSP's DMA controllers to output the video data.
Minimize, minimize, minimize.
Yes, HDMI and either VGA or DVI should do it. I suggest an add on board
for separate audio output. Note that HDMI to DVI + PSDMI boxes do exist.
