Why? There is absolutely no space in the market for something between DVD and whatever new HD format prevails. UMD w/ MPG4 may use half the bandwidth, but it has half the volume too (at least), so there's no gain other than physical size. Unless you believe they cost less to manufacture than DVDs, even at this stage.Panajev2001a said:You bet. I also think that they might be planning Sony Electronics PSP's with video-out and maybe optional add-onms to the PSP to provide secure video-out as 720x480 is a high-enough resolution for DTVs.
Presumably, if the video is stored at 720x480, the PSP will have to do quite a bit of work to resample it down to 480x272. Video playback on the PSP faces a number of problems - constant disc access, MPG4 being CPU-intensive, and the fact that you can't get away with using reduced brightness for watching a lot of films too. It's going to be tricky getting people to buy them, IMHO.They said that SCE's PSP was not the only device using UMDs, so why lock the UMD video resolution to 480x272 ?
