This seems to be the year when the real fight to the
finish over next-generation DVD technology begins. To
date, groups led by Sony and Toshiba, championing the
Blu-ray Disc and the HD DVD format, respectively, have
been locked in a kind of phony war, each maneuvering for
position without much actual combat.
To be sure, the Blu-ray camp got off the first shots
several years ago with the release of some bare-bones
recorders in Japan. Then followed a long standoff, as
the opposing groups sought to find a technological
compromise to bridge their incompatible systems. After
last-ditch talks failed last year, the truce came to an
end this March when Toshiba Corp. shipped the industry’s
first HD DVD players, sparking a barrage of product
announcements and releases from the Blu-ray group.

To get a sense of how those first offerings stack up
against each other and whether next-generation DVD is
all it’s cracked up to be, IEEE Spectrum visited with
Reiji Asakura [photo], a noted digital media reviewer
and critic in Japan who already possesses all available
next-generation recorders and players released there.
Asakura, 55 years old, teaches music theory and the
history of music at the prestigious Tsudajuku
University, in Tokyo. He is the author of 15 books,
including Revolutionaries at Sony: The Making of the
Sony PlayStation and the Visionaries Who Conquered the
World of Video Games (McGraw-Hill, 2000), which has been
translated into Chinese and Korean as well as English.
In what otherwise appears to be a normal family house
on a quiet street in suburban Kawasaki, Asakura has
commandeered the entire first floor of his two-story
home for his hobby-cum-work, forcing his wife and two
children to retreat upstairs. The rooms on the first
level and even the entryway are literally crammed to the
ceiling in some cases, with electronic consumer gear
dating back to a Sony Betamax videocassette recorder;
stacks of industry magazines, technical journals, and
books on hobbies; and about 2000 VHS and Betamax
videotapes. Piled up alongside these are boxes of
records, laser-disc albums, and miscellaneous
incongruous objects like large model airplanes and
bottles of wine.
In the midst of this chaos, Asakura has made space to
set up a home theater, the center of which is a
magnificent motorized roll-up 380-centimeter screen. The
screen is flanked by two towering speakers, part of an
equally impressive 6.1-channel surround-sound audio
system [see photo, “Doing It
at Home”].
Asakura began the visit by demonstrating both
terrestrial and satellite high-definition TV shows he
had recorded on the first-generation Blu-ray recorders.
Sony released the first such recorder in the Japanese
market in April 2003, at a price of 450 000 yen, or
around US $4000 at the time. Panasonic and Sharp
followed with similar recorders the next year, also in
Japan only, and Sharp’s model incorporated a hard disk.
All these products targeted early adopters.
The ability to record high-definition television is
potentially much more than just a geeky interest in
Japan. The country’s national TV network, Japan
Broadcasting Corp., or NHK, has been broadcasting HDTV
programs via satellite since 2000 and began additional
terrestrial HDTV service in 2003. Currently, more than
90 percent of all its prime-time programming is in high
definition. NHK aims to increase this to 100 percent
well before the government deadline of 2011, when Japan
is due to change over to all-digital broadcasting.
The other five major Japanese TV networks are also
broadcasting regularly in high definition, though they
lag somewhat behind NHK. Meanwhile, flat-panel
televisions, capable of displaying movies in the proper
full-width format, are outselling boxy CRT sets, and the
clear trend is for all televisions to incorporate
high-definition tuners.
Asakura played a couple of clips of news programs
recorded in the 1080-line, interlaced high-definition
format. These recordings didn’t do much to make the
talking heads more interesting. But when Asakura slotted
in a Blu-ray cartridge containing a recent live
rendition of the Eagles’ “Hotel California” in high
definition, the result can only be described as the next
best thing to being there. The Blu-ray recording had an
impressive clarity of sound and video, more gradations
of light and shadow, and a wealth of detail down to the
sweat and wrinkles on the faces of the aging rockers.
“When it comes to TV broadcasting, this is not just a
step-up, it’s another world,” says Asakura. “Though to
really appreciate the benefits, you need a large screen
and surround sound.” The impact, he adds, is far less
“if you watch it on a TV of, say, 30 inches.”
Of the three Blu-ray recorders, he prefers using the
Sharp machine, with its hard drive. “This lets you
easily edit and index a program before transferring it
to disc for archiving,” he explains.
To sample Toshiba’s HD DVD technology and
demonstrate how it stacks up against standard DVD,
Asakura used the more expensive of the two
consumer-oriented players that the company launched
earlier this year in the United States: the HD-A1 and
the HD‑XA1, surprisingly low-priced at $499 and $799,
respectively. Asakura chose to compare how the 2004
movie The Phantom of the Opera looked and sounded in the
standard DVD and the HD DVD formats.
Bear in mind that although Asakura was doing the
demonstration on large-scale, state-of-the-art
equipment, average consumers increasingly have the
ability to view DVDs in the wide-screen movie theater
format as well, if that format is available on the disc.
So for those people with LCD or plasma displays, the
difference between a DVD movie and one recorded in the
next-generation format is strictly a question of
resolution, not one of screen shape and size.
In Asakura’s demonstration, while the HD DVD movie
provided more detail, the overall differences—for this
writer at least—were not significant and lacked the
impact of watching the recorded high-definition TV
programs contrasted against a standard TV broadcast
recording. Asakura subsequently explained, however, that
while he uses a standard DVD player, he also uses
additional video-enhancement equipment to upgrade the
viewing of standard DVDs to high-definition quality—a
feature that is incorporated in the Toshiba HD DVD
player and will be in Blu-ray players as well.
Unfortunately, therefore, Asakura’s comparison was
not entirely faithful to what the average consumer’s
experience would be, moving from standard unenhanced DVD
to next-generation video recording.
Still, the way he did the demonstration drew
attention to an important point: the video enhancement
feature in the next-generation players will be a bonus
for early adopters, for they will be able to virtually
turn their current DVD movie collection into
near-high-definition renditions.
This video enhancement feature built into the
next-generation disc players could well encourage
videophiles to buy early models, despite remaining
questions about several issues. Among them are
copy-protection schemes that are still being finalized;
absence of a guarantee that current products can be
updated later to reflect new developments in copy
protection; a dearth of prerecorded movies; and, of
course, concern over whether one of the optical systems
will eventually suffer the same fate the Sony Betamax
videotape format met, when it lost out in the market
against the VHS format in the 1980s.
In light of those uncertainties and despite the
intrinsic appeal of the next-generation players, many
consumers may opt for the time being to keep their
wallets closed and their eyes open.
