(2) (High Definition DVD) A short-lived, high-capacity optical disc that held four hours of HD video on a single-sided, single-layer 15GB disk. Sanctioned by the DVD Forum in 2003, HD DVD gave way to Blu-ray within a few years.

Based on the Advanced Optical Disc (AOD) technology from Toshiba and NEC, HD DVD used a blue-violet laser that read pits half the size of a DVD on tracks more tightly packed. Like Blu-ray, HD DVD supported 1080p resolution and advanced video codecs (see H.264 and VC-1). An advantage for media manufacturers was that, unlike Blu-ray, traditional DVD stamping machines needed only minor modifications to make HD DVDs.

The first HD DVD drives were sold in the U.S. in 2006, and Microsoft offered the drive as an Xbox option. Despite its features and support, in 2008, the majority of movie studios and retail outlets chose Blu-ray over HD DVD, and the "format war" was over.

HD DVD Formats
HD DVD-ROMs were pressed for commercial movies, while HD DVD-Rs were recorded once by the user and HD DVD-RWs were rewritable. A few dual-format HD DVD/Blu-ray players were developed, and hybrid HD DVD/DVD discs were planned. See Blu-ray, HD formats, DVD and DTV.
