Many times it's a word like "multimedia". In other words, it means whatever the marketing guy is thinking about that day ;-). > Does that mean a FULL SCREEN? Yeah. Just no one wants to type out "full screen, full motion". > Does a Dpaint III anim count? Umm. _I_ wouldn't think so. It might, if you meant fullscreen animation. > Does it mean VIDEO RESOLUTION/COLORS? > Does any format/resolution/palette count as long as it is > digitized from a video source? Depends on whose machine it is, of course. A Mac user might be talking about B&W (or full color!), someone else might mean a limited set of colors and/or no overscan, some might include interlace and so on. But generically it means "as close to a normal TV picture as possible". This usually indicates realtime decompression of predigitized video frames. In the case of CDROM stuff, it all has to do with the fact that only about 150K/sec can come off the disc. Divide that up and you can see that serious (de)compression is needed to get a fullscreen at full speed. > What is 'Partial motion video'? Anything not full screen or at 30 frames/second. Eg: displaying back in a 1/4 screen area at 10fps. > .... jus' wondering :-) Don't worry... I'm sure you'll get several definitions (see first above :-). Just priming the pump, myself. cheers - kevin
