Encountering the third generation of DVD format
Author: Dana Scripca
It won't last too long until the third generation of DVD format
to be unveiled. Your DVD player will play a well-performing disc
with high-storage capacity. The upcoming Media-Tech Expo, Las
Vegas, USA, will surely clarify this topical issue.
The upcoming Media-Tech Expo May 10–12, 2005 in Las Vegas, USA
will be a crucial moment in deciding what DVD format will be the
succesor of the actual DVDs. It will be HD-DVD? Or the Blu-ray
Disk? Before the end of 2005, more likely in 2006, the standard
format will be decided for good. The competition between the
HD-DVD and Blu-ray is in full swing now.
The overwhelming increase of portable DVD players led to a even
higher rise of DVDs industry. In 2003, almost 4 billion
prerecorded DVDs were produced. This number is calculated to
increase to 7 billion in 2006. The same for recordable DVDs
market: DVD±R, DVD±RW. While in 2003 just 908 million disks were
produced, it is estimated a double growth rate in 2004 (and
about 4 billion estimated in 2006).
This year edition, from Frankfurt, manufacturing technology for
the third generation of optical storage media has been debated.
More than 1,400 people joined 2004 edition. At upcoming 2005
edition, concepts for replication lines and single components
for the manufacturing of HD-DVD and Blu-ray Disc will be
introduced. Media-Tech Expo is the leading annual tradeshow for
the media manufacturing industry.
As for these two vying formats, both use a blue laser (contrary
to red laser for DVDs). The blue laser has a shorter wavelength
leading to finer signal markings on the optical media. Moreover,
a shorter wavelength, associated with advanced compression
process, prompts a higher storage capacity. Whereas HD-DVD holds
30 gigabytes, Blu-ray holds 50 gigabytes on a double-layer disc.
Professional video industry is one of the most prosperous. Not
surprisingly, engineers and manufacturing professionals,
producers, video and audio professionals, web developers,
broadcasters, directors, DVD authors, editors, graphic artists,
gather on annual worldwide electronics and digital video
exhibitions to learn the newly techniques, technologies,
capabilities, advantages related to their industry. There are
seven major exhibitions: DV-Expo, Mediacast, DVD Europe, DVD
Replication Exhibition, DVD Summit - Midle East Asia,
