western market consumers deal with HD DVD, Blu-ray Disc, and perhaps soon HD
VMD, the Chinese market will get its own separate high-definition optical
format specific to its region.
Optical Memory National Engineering Research Center (OMNERC), a laboratory
dedicated to optical disc research at Tsinghua University in
Beijing, announced last week CH-DVD – which stands for China High Definition
DVD – as a new generation high definition DVD format.
than developing a completely new technology, CH-DVD is based on HD DVD
technology, which means the employment of blue-violet lasers rather than the
red lasers used in regular DVD.
development and realization CH-DVD technology is supported by the Chinese
government. It is currently unclear if the DVD Forum – those responsible for
the HD DVD specification – had any part in developing the format. The Chinese
group behind CH-DVD, however, is partnering with the DVD Forum and other
related bodies to form the China High Definition DVD Industry Association.
in hopes of keeping the abundance of piracy in China at bay, CH-DVD is said to
adopt an “advanced copy protection technology” that the Chinese government
hopes to effectively prevent the spread of pirated copy. It’s unknown if CH-DVD
is using a new form of copy protection, though the AACS scheme used
by Blu-ray Disc and HD DVD was defeated earlier this
China High Definition DVD Industry Association said that it will “make a big
push to launch CH-DVD player into the Chinese market in 2008” and “encourage
all related industries to... to make the transition from standard definition
DVD to high definition DVD.”
the development of a foreign high-definition format may be relatively
meaningless to North American and European consumers, the fact that China is
formally adopting a blue-violet laser technology could have far reaching
effects on production costs of Blu-ray Disc and HD DVD hardware.
that the optical assemblies for CH-DVD are similar, manufacturers of HD DVD and
Blu-ray Disc players may be able to take advantage of the scale of Chinese
production. Inexpensive, made-in-China high-definition machines have already
been begun showing up on the radar with Venturer Electronics’
HD DVD player along with the hint of Wal-Mart’s
own special HD-player deal.
