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.

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. -- JRT _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
--- what about the Cell Broadband Engine Family? IBM wants folks to sign on pretty badly. It may simplify getting the "processing power/bandwidth" needed. I doubt it would make the design overly easy. --- As far as audio, i hear Dolby has some sweetheart incentives going to get better PC market penetration. --- Display Port just recently was upgraded. I hear they may even support Optical connections. --- There probably will be a market for H.264 and MPEG 4. Basicly you would be trying to enter the home entertainment pc market. With basic video card functions. --- Probably better think about DRM legalities. Interesting proposals. Gary
