HD DVD (short for Heich-Defineetion/Density DVD) is a discontinued heich-density optical disc format for storin data an heich-defineetion video.[1] Supportit principally bi Toshiba, HD DVD wis enveesioned tae be the successor tae the staundart DVD format. In Februar 2008, efter a protractit format war wi rival Blu-ray Disc, Toshiba abandoned the format, annooncin it na langer developed or manufactured HD DVD players or drives.[1] The HD DVD physical disc specifications (but nae the codecs) wur still in uise as the basis for the Cheenae Blue Heich-defineetion Disc (CBHD) formerly cried CH-DVD.
