v1.0 of HD-DVD Physical Specs Approved

Posted by CmdrTaco on from the the-race-is-on dept.

Repran writes "The DVD Forum this week approved HD-DVD 1.0, a specification that will compete with Blu-Ray which is not yet approved for the future of the DVD disc format. This effectively gives manufacturers a green light to begin producing devices. In related news Microsoft's VC-9 codec has been included in the official HD-DVD specs."

    HD-DVD format uses a 405nm-wavelength blue-violet laser technology, in contrast to the 650nm-wavelength red laser technology used in traditional DVD formats. The rewritable Blu-ray disc, with a data transfer rate of 36Mbps, can hold up to 27GB of data on a single-sided single layer disc (compared to the traditional DVD's 4.7GB capacity), which amounts to about 12 hours of standard video or more than 2 hours of high-definition video.
    AOD is pretty much the same, except it has a storage capacity of 20GB on a single-layer disc
