Many of you already have a DVD
burner in your computer. Yet at 4.7 GB it still seems small
when trying to backup hard drives of 100 GB or larger. Even
with the new dual layer DVD burners this is still a problem.
With Sony and JVC having video cameras in the new HDV format
corporate, governmental, educational, event, and high-level
amateur videographers will be able to produce high definition
videos. There are predictions that in less than five years
HDV cameras will replace standard definition DV cameras at
the consumer level. Yet the current standard DVD format can
only have half an hour of high definition video put on them.
The upcoming blue laser DVD formats may be the answer to these
issues. However, there are forces that are expected to provide
some chaos and confusion in their introduction, which will
include another format war.
There are some blue laser DVD type of recording devices already
on the market, but like DVD-RAM that came early in the DVD
product life cycle, they are targeted toward a narrow market
and wide use is not to be expected. There are three different
viable blue laser DVD formats proposed, but all will use disks
that are the same diameter as standard DVDs.
The first is HD-DVD. This is from the DVD Forum, the same
people that brought you the DVD. The storage space on this
is up to 20 GB single layer and 40 GB dual layer (15 GB &
30 GB for ROM and recordable, 20 GB & 40 GB for rewritable).
Some companies were not satisfied with what was going on
within the DVD Forum in regards to HD-DVD. This group was
lead by Sony, which came up with the Blu-ray Disc. The storage
space on it is up to 25 GB single layer and 50 GB dual layer,
with the possibility on increasing the number of layers to
as many as eight later. Both HD-DVD and Blu-ray Disc players
will be able to play standard DVDs and CDs. Both formats will
at least use the video codecs MPEG-2 Hi-Def/Standard-Def,
MPEG-4 AVC High Profile, and Windows Media 9. They will also
have native multi-track surround sound to be used in 5.1 sound
systems or higher.
There is also a standard being used in mainland China called
EVD. It was developed as an alternative to DVD so the Chinese
would not have to pay the DVD licensing fees and to keep local
control of the technology. It has made its way to some surrounding
countries. The plan is to extend the standard to incorporate
blue laser and other more up-to-date technologies making it
comparable to the other two viable competing high definition
DVD formats.
The winner should be either HD-DVD or Blu-ray Disc. The blue
laser EVD is only expected to be a widely used format in Asia.
Blu-ray has the backing of more hardware manufacturers (Sony,
Dell, Hewlett Packard, LG, Panasonic, Pioneer, Philips, Sharp,
Samsung, & others) than HD-DVD (Toshiba, NEC, Sanyo, and
others). Both have lined up Hollywood studios amounting to
about half of the current DVD movie sales (HD-DVD: Universal,
Paramount, Warner Brothers, & New Line Cinema. Blue-ray:
Sony, Twentieth Century Fox, & Disney).
Right now Blu-ray Disc is considered to have a slight competitive
edge over HD-DVD, but it could go either way in the expected
long drawn out fight like there was between VHS and Betamax
videotape formats.
For the price to come down on high definition DVD players
and writable/rewritable drives to the consumer and general
office use levels there needs to be a perception by the manufacturers
that there will be a high demand for these products (mass
production begets low costs). Last time it was the release
of major Hollywood movies on the DVD format that caused this
demand, so the manufacturers are thinking it will be the same
this time. This allows the Hollywood studios to have great
influence over the next generation DVD formats.
The movie standards for both HD-DVD and Blue Ray Disc are
finalized. However, the standards for interactivity on the
disk and Internet/Web are not expected to be finalized until
early 2006, which mean they won't be included in players until
late 2006. Some of the Hollywood studios have expressed that
they do not want players out there that will not have the
full functionally that they would wish. This is a problem
of them not wanting to make decisions on a mixed installed
base and then requiring first adopters to have to replace
their player to get full functionally of the format within
two years. This also allows them more time to work on their
new 128 bit encrypted disk copying protection/digital rights
management system called Advanced Access Control System (AACS).
However, many of both the HD-DVD and Blu-ray manufactures
have announced they plan to release players by late 2005.
Hewlett Packard says they also want to start including Blu-ray
writable drives in their desktop computers starting in late
2005 and notebooks in 2006. Sony's Playstation 3 to come out
in 2006 will be able to use Blu-ray discs.
However, there is a question about how many movies will be
released in the formats, the lack of which could delay the
launch of the players. Yet it is likely the competition between
HD-DVD and Blue-ray will mean the players will launch on schedule
anyway.
The proposed next generation DVDs will have 4-5 times the
storage capacity of current standard DVDs. It is expected
that there will be another face off between standards, this
time between HD-DVD and Blue Ray Disc. There could be a delay
in the wide scale distribution of players and recorders because
of Hollywood's influence and the delay in interactivity standards
for the formats, but competitive forces will probably mean
the late 2005 launch will go ahead as scheduled. It is too
early to tell which format will win.
