maybe you could try some sophisticaded dithering scheme, but it will probably look ugly and I'm not sure whether it's worth the efforts. And then there is another problem: some MHP expect single-buffered displays, so you need to copy the OSD surface continously for them...IIRC you need a full-color display. A more serious problem is that the MHP spec requires at least an OSD, a video and a stillpicture layer, maybe even multiple still layers (maybe these could get faked using the window stack). But that's just like I remind things, if anybody here has the specs handy please check and report whether my memory is true...@Holger: would a full screen, 256 color OSD be sufficient for MHP, or does it requite even more?
The three layers are background, video and graphics. Colour model is stated to be "logical truecolor"... as we have to keep in mind, that multiple jpegs are allowed and even mpeg2 video driplets (but this I don't remember very exactly)
, 256 colors are not suffisant.
