The HD-DVD (High Definition/High Density-DVD) next-generation
optical disc format got a boost Monday with the announcement by
Toshiba Corp. and NEC Corp. that they plan to launch compatible
products next year and with word that a major Japanese content producer
is backing the format.
Toshiba and NEC announced their plans to launch
HD-DVD hardware during the 2005 calendar year as a three-day event
aimed at promoting the standard to Japan's entertainment industry
got under way in Tokyo. Toshiba plans a home player and possibly
a recorder while NEC said it plans a drive for use with computers.
At the same event Pony Canyon Inc., Japan's largest
distributor of DVDs, said it plans to release content in the format
and named the first eight discs it plans to produce.
The promotional effort aims to push HD-DVD toward
victory in what has been until now a one-sided race to become the
format of choice for high-definition video content.
To date demonstrations of HD-DVD have been largely
confined to prototype models on show at technical seminars and some
events. In contrast recorders based on the competing Blu-ray Disc
are already on the market. Sony commercialized the first in 2003
and Matsushita Electric Industrial Co. Ltd., better known as Panasonic,
will put the second on sale in Japan this weekend.
The HD-DVD group, which is mainly led by Toshiba
and NEC, is using the technological differences between the two
formats as the basis for its argument that HD-DVD makes more sense
than Blu-ray Disc and hopes the entertainment industry, both in
Japan and elsewhere, is listening.
The industry is a tough crowd to please, said Toshio
Yajima, a senior executive advisor to Microsoft Corp.'s Japan unit,
Microsoft Co. Ltd. "They like to say no," he said.
But both sides in the format battle know that without
the support of movie studios and entertainment companies their respective
formats could be dead in the water.
Toshiba and NEC are appealing to the collective
wallets of the industry.
Because HD-DVD discs are almost physically identical
to current DVD discs, the same production lines can be used to produce
both discs, thus saving the expense of building new factories, said
Masato Ootsuka, senior manager of the engineering development department
at optical disc maker Memory-Tech Corp.
A pilot line at the company's factory in Tsukuba,
north of Tokyo, can be switched between DVD and HD-DVD in five minutes
and production of a dual-layer 30GB HD-DVD disc takes 3.5 seconds,
compared to 3 seconds for a DVD, Ootsuka said. Yields are also above
90 percent.
Hardware will also be cheaper to make because its
closeness to DVD means it is less complicated, the companies say.
While Toshiba and NEC wouldn't comment Monday on
the likely price of their first products, Hisashi Yamada, chief
fellow of technology at Toshiba and also a chairman at the DVD Forum,
said at an event in Los Angeles earlier this year that he expects
the first players to cost around ¥100,000 (US$910), according
to the company. Panasonic's Blu-ray Disc recorder due on sale this
week will cost around ¥300,000.
The group is also pushing the message that, while
HD-DVD offers a lower data storage capacity than Blu-ray Disc, HD-DVD
can store more high-definition programming. That's because it uses
the MPEG4.AVC and VC9 codecs, the former based on the H.264 codec
and the latter on Microsoft's Windows Media 9 codec.
HD-DVD's codecs are more efficient than the MPEG2
system used in Blu-ray Disc can reduce the file size by two thirds,
said Microsoft's Yajima. That means one 15GB disc can hold 180 minutes
of high-definition video. A 29GB Blu-ray Disc can hold around 132
minutes of video, which is not long enough for around 5 percent
of movies, he said.
One stumbling block to widespread support is the
lack of a strong copy-protection and digital rights management system.
However this work is underway and details are expected to be published
soon, Yajima said.
The problem of illegal copying was highlighted
in a recent report by the Motion Picture Association of America
Inc. that said an average of 24 percent of Internet users in eight
major countries have downloaded a movie and estimated losses to
the movie industry from such piracy run into billions of dollars.
With the promotional event in Tokyo this week and
Panasonic's imminent launch of its Blu-ray Disc player it appears
the long-anticipated battle between the two sides is now beginning.
The Blu-ray Disc camp is targeting recording of
high-definition programs, but this could hamper it in markets where
high-definition programming has yet to take off. The HD-DVD team
is seeking victory through the backing of entertainment companies
for prerecorded content and hoping users are more interested in
watching such content than time-shifting television.
