QuoteHD 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.
QuoteToshiba has submitted a triple-layer, 51GB HD DVD-ROM disc to the standard's overseer in the hope the technology will be adopted as a standard by the end of the year. If approved, it allow the format to exceed the 50GB storage capacity of rival medium Blu-ray Disc. The HD DVD standard currently defines single- and dual-layer discs capable of holding 15GB and 30GB of data, respectively. That's plenty, say the format's supporters, for a movie encoded in 1080p HD resolution and a stack of extras.
