DVD Forum punts blue laser HD-DVD
The DVD Forum has begun to promote its second-generation DVD specification to Taiwanese drive manufacturers.
The organisation, which oversees the DVD format, approved a blue laser-based format, to be called HD-DVD, last November. The technology came from Toshiba and NEC, rather than the Blu-ray format backed by Sony, Pioneer, Samsung, Matsushita Electric, Philips and others.
Unlike Blu-ray, the Toshiba/NEC system retains backwards compatibility with today's DVD specification, allowing HD-DVD machines to play older discs and ensuring disc manufacturers can more easily re-tool their production lines for the new format.
By contrast, Blu-ray requires all-new equipment. However, supporter companies are already offering Blu-ray machines. Sony shipped its pro-oriented rewriteable 23GB Professional Disc for Data (PDD) last December, and is preparing a second-generation 50GB consumer version which it will use in a TiVo-style personal video recorder later this year. Similar models from other Blu-ray supporters - most notably Philips and Matsushita/Panasonic - are expected this summer to coincide with the Olympic Games.
