Do we need yet another new HD format disk? The new entry will be able to use a red laser to hold 30GB per disk. That's pretty impressive. HD-DVD and Bluray both use blue lasers (which has a shorter wavelength).


HD VMD discs, which hold up to 30GB on a single side, are encoded with a maximum bit rate of 40 megabits per second; that's within halfway between HD DVD's 36 mpbs and Blu-ray's 48 mbps. The format uses MPEG-2 and VC1 video formats to encode at 1080p resolution for the time being, and will possibly move to the H.264 format in the future. Levich said the video quality is "at least as good" as that of the other formats. Using a projection system, HD VMD reps showed me clips of "We Were Soldiers" and "Apocalypto." The movies looked very good--not as stunning as I expected, but I'd just arrived from the CEDIA show floor, where every television vendor uses phenomenal, highly doctored content to show off their products.
