WD’s 1394 A/V HD, Incorporating Technology Developed by Sony U.S. Research
Designed to Further Enable Digital Consumer Electronics and In-Home

Western Digital Corporation demonstrated its IEEE-1394 audio/video hard
drive (A/V HD) technology at the Consumer Electronics Show (CES), January
6-9, 2001 at the Las Vegas Convention Centre.

Western Digital’s 1394 A/V HD is the first technology to deliver both
asynchronous and isochronous capabilities by using IEEE-1394 digital
interface technology developed by Sony’s Interconnect Architecture
Laboratory (IAL), one of the U.S. Research Laboratories of Sony
Inc. The unique combination of these capabilities enables a rich set of
functionality for the future development of both a computer peripheral and
consumer entertainment product.

"The 1394 interface has seen increasing visibility in both PC and consumer
applications. Western Digital’s A/V hard drive is a clear example of a
device that uses 1394 to cross the narrowing line between these two
industries." said Scott Smyers, vice president of Sony’s San Jose,
Calif.-based Interconnect Architecture Laboratory.

The 1394 A/V HD technology enables simultaneous recording and playback of
MPEG2 video (high definition and standard definition), DV (Digital Video)
and audio streams, making it an ideal solution for delivering optimum
performance and ease-of-use for in-home networks, digital video recorders
and other digital consumer electronics. Implementing an embedded file
system to manage and control the streaming content also adds to the
capabilities and performance of the HD. This technology also includes the
"5C" DTCP copy protection technology in order to prevent the unauthorised
use of copy-protected content that the A/V HD might store.

"Industry insiders are carefully watching 1394-capable storage technology,
as they ready their digital product plans for 1394 interconnection," said
Robert A. Perry, director of marketing, Mitsubishi Digital Electronics
America, Inc. "It seems clear that 1394-capable digital A/V devices will
achieve critical mass very quickly, with 2001 being the formative year."

Several companies have realised the benefit that Western Digital’s 1394
HD technology brings to the consumer electronics market and will be
showcasing the product as part of their CES demonstrations. Among the
companies that will be utilising the technology in their demos are Keen
Personal Media (booth #24823), Texas Instruments (booth #2015), TeraLogic
(suite at the Mirage), VividLogic (#24937 - HAVi suite at the Four Seasons
Hotel) and Digital Harmony (booth #3747).

VividLogic, a leading supplier of IEEE-1394 and HAVi (Home Audio Video
interoperability) software, will display a sample home A/V network
demonstrating multi-device, multi-vendor interoperability using HAVi
software that includes Western Digital’s 1394 A/V HD technology. The demo
will showcase VividLogic’s FireBus IEEE-1394 and HAVi software which
the 1394 A/V HD technology to have a graphical interface that runs on
devices such as digital TVs, set-top boxes and residential gateways in the
home network.

"The coupling of Western Digital’s A/V HD technology with VividLogic’s
based FireBus technology will enable seamless interoperability for CE
devices within home networking infrastructures," said Shiva Patibanda,
executive officer, VividLogic Inc. "This technology delivers an unmatched
ease-of-use for CE devices. The consumer simply connects the cables."

By implementing both HAVi technology and 1394 A/V HD technology digital
entertainment system OEMs will be able to easily develop applications and
systems that can stream content to and from other HAVi-enabled devices.

"There is a huge opportunity for this 1394 technology to benefit the
CE devices and in-home networking infrastructures," said Samuel A.
Muscariello, senior director of marketing with Western Digital. "We see
components such as set-top boxes, television sets, game consoles, juke
boxes, and ultimately the end-user benefiting from this technology as it
will provide the capability for additional features not commonly available
today. As 1394 continues to become the dominating consumer electronics
external attach interface, we fully expect an increased demand from CE
manufacturers for 1394 A/V HD technology."
