Total Hi Def

From Wikipedia, the free encyclopedia

Total Hi Def Disc, also called a Total HD or THD, was to be an optical disc that included both rival high-definition optical disc formats, Blu-ray Disc and HD DVD.^[1] It was officially announced January 8, 2007 at Warner Bros. / Warner Home Video's press conference held at CES 2007.^[2] One side was to contain a single or dual-layer Blu-ray Disc, and the other was to contain a single or dual-layer HD DVD.^[3]

However, in November of 2007, Warner Brothers cancelled development of the Total HD discs ^[4] after several delays. Finally, on January 4, 2008, Warner Bros. Pictures announced that they are discontinuing HD DVD support, putting an end to any possible future of THD.^[5]
