Titolo: HD il prossimo anno

Sarà il 2005 l’anno del debutto della nuova tecnologia Dvd a laser blu
(Hd-Dvd). Lo annuncia il Dvd Forum, riunitosi a Tokyo, che raccoglie
tutti i produttori aderenti al nuovo standard.
Questa nuova tecnologia, che utilizza frequenze più ristrette e ha
quindi la possibilità di archiviare e leggere dati a una densità
maggiore rispetto alla vecchia tecnologia a laser rosso, presenta
anche diversi punti di forza nei confronti della concorrente blu-ray.
Da non trascurare, per esempio, il fatto che sia compatibile con gli
attuali lettori Dvd, che potrebbe consentire un passaggio più graduale
e costi inferiori degli apparecchi; inoltre, è in grado di supportare
più formati video, oltre al Mpeg2 in uso per il blu-ray, tra cui
l’H.264. Questo lo renderebbe più appetibile soprattutto nell’ambito
della registrazione di video e film in tempo reale.
A dare man forte a questo nuovo standard, la recente dichiarazione di
Microsoft che intende supportare il formato sul nuovo sistema
operativo Longhorn. In realtà, la posizione della società americana è
meno sbilanciata, dato che è vero che supporterà questo standard, ma
non ha negato nemmeno l’appoggio alla tecnologia concorrente blu–ray.
I produttori che hanno aderito all’Hd-Dvd, tra cui Toshiba e Nec che
sono le aziende che hanno dato vita allo standard, sono fiduciose di
poter superare la concorrenza e nel giro di cinque anni poter
diventare lo standard alla base della videoregistrazione digitale.

Lasers may be the weapon of choice for sci-fi movie heroes when the
fate of the galaxy hangs in the balance. But back here on Planet
Earth, lasers are at the center of a movie battle of another kind: the
one among Japan's giant electronics manufacturers over the next
generation of DVD technology. The winners will get to set the course
of the home-video entertainment industry for perhaps the next decade
or longer — and reap billions in licensing royalties in the process.
With the convergence of the TV and the PC finally becoming a reality,
the technical specifications of tomorrow's DVDs have the potential to
affect the development of not just movies but also console video games
like the Xbox and PlayStation, the operating systems of Macintosh and
Windows computers and a host of other interactive technologies. And
Sony's recent successful bid for MGM Studios (and its rich backlist of
classic films) underscored just how crucial DVDs are in the
entertainment and electronics businesses. The current scuffle might
not be settled before two competing (and incompatible) standards reach
stores, potentially blossoming into a confusing standards war like the
VHS-vs.-Betamax videotape clash of the late 1970s and early '80s.
At issue are two blue-laser technologies that will drive tomorrow's
DVD players. Both formats enable far more information to be packed
onto discs the same size as traditional DVDs (which are read by red
lasers). The two new varieties also offer strong copyright protection
and far greater picture clarity, making them well suited to
high-definition television as well as to computer screens. Beyond
that, there are differences in price, storage capacity and other
technical details.
Spearheading one camp is Sony, which is promoting a technology it
calls Blu-ray. Sony quickly enlisted Matsushita, Philips and Pioneer,
among others, as allies in its cause. All was going well in this
spirit of selfless cooperation, Sony claims, until Toshiba decided to
ruin the party. "We have had many, many meetings with Toshiba," says
project director Kiyoshi Nishitani. But when it came to explaining the
benefits of joining the alliance, he adds with a shake of his head,
"we could not get them to understand."
Toshiba's DVD executives cheerfully avow that they spurned the Blu-ray
consortium's advances, deciding to develop their own HD-DVD technology
instead. The proud victor over Sony in setting the standards for the
first generation of DVDs in the 1990s, Toshiba is in no mood to
concede its lead. Toshiba team leader Hisashi Yamada, a key player in
the first DVD war, seems to delight in playing the role of the spoiler
yet again in the face of what many at Toshiba perceive as Sony's
arrogance. "The way of Sony is very simple," says Yamada. "'Our format
is best,' they say. 'You should adopt it,' they say. Only that. No
compromise." But, he adds with a mischievous grin, "we did not think
Sony's is the right technology at the right time. We think ours is
better."
Both companies claim they have attracted a critical mass of
supporters. Sony has enlisted Hitachi, Samsung, Sharp, LG and Dell,
among others. Toshiba trumpets the fact that Microsoft has pledged
that its next Windows operating system will be compatible with HD-DVD.
There is one thing that everyone agrees is essential to victory:
Hollywood support. "The vote is in Hollywood's hands," says Warren
Lieberfarb, a former head of Warner Home Video and currently a
consultant for Toshiba. Home rentals and sales can generate as much as
50% of a film's revenue, and in the DVD-format wars, the studios all
want to bet on a winner.
