DVD Forum OK's HD-DVD 1.0 for Next-Gen Debate11 Jun, 2004 By: Erik Gruenwedel
As expected, the DVD Forum, a Tokyo-based association of hardware manufacturers and software firms promoting the DVD format, has authorized HD-DVD 1.0 as a ROM specification contender against rival Blu-ray Disc.
The new specification — approved Thursday — represents a codex upgrade from MPEG-2 (HD-DVD 0.9) to MPEG-4 (HD-DVD 1.0) that would allow a capacity of 15 gigabytes (GB) per a single-layered side or 30GB for a dual-layered side.
Approval of HD-DVD 1.0, which is backed by Toshiba and NEC, does not constitute an increase in capacity, rather it is endorsing improved codex used to encode digital content, according to Jon Peddie, president of Jon Peddie Research, Tiburon, Calif.
“By using an MPEG-4 type codex, you are getting the effective storage capacity of 15GB or 30GB on a conventional 4.7GB DVD disc,” Peddie said.
Rival Blu-ray — backed by Sony, Dell and Hewlett-Packard, among others — uses MPEG-2 and an aperture that is alleged to be 80 percent more concentrated than a current DVD. The Blu-ray Disc claims storage capacity exceeding 50GB of data.
Blu-ray specifications and actual disc will be introduced in mid-July, according to company officials.
