SANYO Develops a Breakthrough
LSI for HD DVD
Thursday, August 18, 2005
The world?s first HD DVD, DVD and CD compatible
one chip LSI.
As we have already posted in our site ,
Sanyo has made HD-DVD recording an option previously
considered years away.
Of course, we do not know if this can be put
easily into mass production and when this, beyond
wishful marketing, can be done! (Given the bad
company past record of pushing into market near-obsolete
technologies, like 1.4GB CD recording when the
consumer's attention had already been shifted
toward DVD recording, a mistake that finally
forced the company to get out of the DVD-+R
business prematurely!)
Below is the official Sanyo release about the
new LSI. (Fortunately, this Japanese company
does not use Systran for translating its releases
to human readable English:)
SANYO Electric Co., Ltd. (SANYO) has developed
a signal processing LSI for HD DVDs, the next
generation consumer disk system. SANYO achieved
on one chip, playback and recording of HD DVDs,
current DVDs, and CDs. By utilizing this LSI,
it is possible to lower costs and reduce the
size of the HD DVD drive and HD DVD player hardware.
?SANYO is proud of the role we continue to play
in developing HD DVD based system level solutions
and components including our own branded player
to be launched in fiscal year 2005.? stated
Dr. Keiichi Yodoshi Deputy General Manager of
SANYO?s R&D Headquarters, ?HD DVD is advantageous
because of its superior compatibility with current
generation DVDs and low cost production for
ROM disks. This will prove to be a big edge
in popularizing HD DVD ROM contents?.
SANYO plans to release this key component LSI
to the market the second quarter of 2006.
With the expected rapid proliferation of products
in the consumer electronics field, HD DVD players
and recorders that utilize this LSI will quickly
appear in the market.
Major Features
The HD DVD encoder/decoder circuit, the DVD
and CD encoder/decoder circuit and the CPU were
all integrated in one chip. This simplified
circuitry enables the record and playback of
HD DVDs, DVDs and CDs.
The newly developed HD DVD digital read channel
circuit and adaptive control circuit, enables
high quality signal playback for each HD DVD,
DVD and CD disk.
Successfully made the LSI size compact by integrating
the DVD/CD circuit and the HD DVD circuit with
the error correction circuit block. By optimizing
various signal processing architectures, SANYO
achieved full backwards compatibility. As a
result, along with making the overall circuit
area smaller, SANYO was able to achieve compatibility
with HD DVD, DVD and CD, which will lead to
a reduction in costs and lower power consumption.
