LAS VEGAS, Nev. ¡X In response to a growing demand among
consumer-electronics manufacturers for digital-audio receivers to run
several decoding algorithms, Zoran Corp. is unveiling a digital-audio
processor, ZR38650, at the Consumer Electronics Show to be held here this
week.

Although it's based on the company's three generations of
digital-audio-processor architecture, Paul Goldberg, vice president of audio
products, said, "We designed this new audio processor as the first true
multi-format decoder."

Featuring a faster processing speed and larger on-chip memories, the
processor is designed to process numerous complex digital-audio
compression schemes besides Dolby Digital, including Digital Theater
Systems (DTS), MPEG-2 Multichannel, MP3, MPEG-2 Advanced Audio
Coding (AAC) and Meridian Lossless Packing (MLP).

According to Zoran, the demand is growing for a multi-format digital-audio
processor for high-end audio receivers, DVD players and a variety of
entertainment systems with a broad range of audio/video quality features.
"From a boom box to a regular CD/DVD player, to a high-end DVD-Audio
player, your chip coming out in 1999 needs to address the entire spectrum of
various audio-decoding requirements," said Goldberg.

For the audiophile market, DVD-Audio, whose spec is finally coming
together, is expected to present new challenges to a lot of system and chip
vendors in 1999. MLP, for example, has been chosen as a lossless packing
technology required for DVD Audio.

Meanwhile, MPEG-2 AAC, which has been chosen as the audio
requirement for satellite-based Japanese Digital TV service, is now seen as
a low-bit-rate audio algorithm ideal for delivery of downloadable CD-quality
music over the Internet, satellite or cable. And MP3-a virtual de facto
audio-compression algorithm used on the Internet to download music
today-continues to exist, despite the latest efforts by the Recording Industry
Association of America (RIAA) to set an audio standard for secure digital
music sent over the Internet.

As the distribution of music over the Internet becomes more popular, the
importance of a multi-format decoder could become even more relevant.
Especially in the future, when consumer-electronics-system vendors start
thinking about building such a new standalone consumer device as "Internet
Radio," the ability of that system to decode multiple audio algorithms should
become a must, the Goldberg predicted.

Today, such algorithms as MP3, AAC and MLP are still in development at
Zoran. The DTS is in the process of final approval, Goldberg said.

The ZR38650 has such expanded on-chip memories as 2 kword
program/data RAM, 10 kword data RAM and 20 kword program/data
ROM. The larger on-chip program RAM, for example, is used to store
Dolby Digital, Dolby Prologic and MPEG-2 Multichannel audio, as well as a
base management algorithm.

Further, by featuring a full 32-bit external bus to connect to SRAM, the new
digital-audio processor can directly access off-chip program/data memories.
The external memory becomes essential "if users want to run very large
programs such as DTS, MLP and AAC," said Goldberg. "As the price of
SRAM is going down, it's becoming very feasible."

The ZR38650, running at 100 MHz, has 50 Mips DSP processing power.
The company's previous digital-audio processor, ZR38600 offered 40 Mips
processing power, running at 80 MHz. "The 10 extra Mips can now allow us
to process a number of different virtual-surround-sound schemes as well,"
said Goldberg.

The chip, manufactured by using a 0.31-micron process technology, is
available today. The chip will be priced "less than $12" for customers
wanting it for large-volume quantity, said Goldberg.

The TV will become an important product area that offers greater growth
potential.

At CES, the TV becomes the network

By Junko Yoshida

LAS VEGAS - As the top design managers of the major consumer
electronics companies descend on the Winter Consumer Electronics show
here next week (Jan.7-10), the winds of change seem to be blowing from a
new direction. The quest to design a killer convergence product such as a
PC/TV is over. Instead, engineers at the top suppliers have set about
developing a host of distributed, connected digital devices in an environment
where networking, Java-and a good deal of partisan politics among
technology factions-are on the rise.

“Political infighting or a lack of compromise among those participating in
the industry groups' discussions is my biggest concern,” said Rodger Lea,
vice president of the Distributed Systems Laboratory at Sony U.S. Research
Laboratories (San Jose, Calif.). “I'm concerned that a real message to our
consumers could easily get lost,” Lea said. “We are not telling them what
the real added value of digital TV is.”

Sources said politics is also to blame for the fact that the OpenCable
specification for a standard digital set-top box has fallen seriously behind
schedule-a fact that Paul Liao, chief technology officer and president of
Panasonic Technologies Inc. (Princeton, N.J.), said is his biggest lingering
concern. The culprit, Liao said, is “different companies refusing to work
together.”

Surveying the landscape of nascent digital consumer products, Cees Jan
Koomen, president of the digital video group at Philips Consumer
Electronics, spies an imminent crisis for manufacturers, given that “analog
TVs [are] maturing and the demand for PCs [is] also maturing.” Koomen
predicted that technology issues surrounding many digital consumer devices
would remain “fluid” throughout 1999.

One area where consensus appears to be forming is in the need for
connectivity, generally enabled by Java. Though sources said no one
company or technology will dominate the digital consumer space in the way
Wintel has ruled the PC, Java “has gained dominance in the last six months
” in the consumer-electronics industry, said Koomen.

For example, said Sony's Lea, key consumer players along with several
other companies are working to define a digital-TV application programming
interface, tentatively called Java.TV. Though many of its activities are still
under wraps, the Java.TV collaboration has speeded up since Sun opened up
its licensing policy a few months ago, according to sources close to the
project.

Java.TV is not a subset of PersonalJava or EmbeddedJava, but rather “a
set of APIs defined [to be] suited for television,” said Lea. Although
becoming a PersonalJava licensee is not a requirement to participate in the
discussion, Panasonic's Liao, whose parent company recently took a
PersonalJava license, said, “it always helps facilitate things.”

Not everyone is sold on Java, however. Microsoft Corp. and Thomson
Consumer Electronics, for example, are working together to define what's
necessary for the next-generation television, which they have dubbed eTV.
“A Java-like solution is certainly under consideration, but we haven't got it
all defined yet,” said Ed Milbourn, manager of advanced-TV product
planning at Thomson.

Beyond the TV effort, a Java Virtual Machine is expected to go inside many
advanced digital consumer systems, serving as a glue and as a run-time
environment. The result, said Sony's Lea, will be “a higher level
interoperability” among devices compliant with the HAVi (Home
Audio-Video interoperability) home networking spec agreed upon last year
by eight consumer electronics companies. They are Grundig, Hitachi,
Matsushita, Philips, Sharp, Sony, Thomson Multimedia and Toshiba.

A set of HAVi APIs based on Java will give an independent consumer
system the power to remotely execute applications, provide a graphical user
interface or upload Device Control Modules written in Java byte code. Such
applications or modules need not be pre-installed in each embedded system;
the HAVi API enables each device to send the capabilities it needs to other
devices over the home network.

Indeed, networking is becoming a mantra for consumer companies. Their
object is to build a home network infrastructure so that “suddenly, a newly
bought digital consumer appliance is no longer just another standalone box,”
irrelevant to the rest of the systems, said Lea. Connectivity-or distributed
computing power on the home network-should breathe new life, new value
and new capabilities into home digital consumer electronics, he said.

Industry-wide efforts to lay the groundwork for a home networking
infrastructure have only begun. This spring, Panasonic plans to launch a
5.7-GHz wireless PC multimedia transceiver system called MicroCast.
However, Liao acknowledged that Panasonic remains totally undecided
which technologies-RF, telephone or power lines, IR or cable-may become
the mainstream pipe to deliver audio, video and data within the home
network.

Nevertheless, the birth of HAVi this year laid the cornerstone for “a much
more complete paradigm for networked and distributed computing,” Liao
said. He sees the network as the key driver “to draw the technologies
together” in 1999 and beyond.

But debate is raging over just what that network should be or do. “The
added value of home networking needs to be more than just something
engineers in Silicon Valley want to do at home,” said Simon Dolan, vice
president of marketing at the consumer division of LSI Logic Corp. (Milpitas,
Calif.).

Philips' Koomen argued that the vision for home networking exists at a much
more fundamental level. When a consumer buys a new multichannel audio
receiver, for example, the system itself-through the home network-should be
able to register its presence and capabilities. It should introduce itself to the
rest of the digital entertainment systems already installed, letting them know
what it does and how the others can use the receiver's new multichannel
capabilities.

“The system should be able to take care of itself, without having consumers
get involved in complex setup procedures,” he said.

Sony's Lea goes a step further. “A user ultimately shouldn't even have to
care which device within the home needs to be activated in order to listen to
his or her favorite song,” he said. Showing the HAVi-based in-house
network system demo that's installed in his lab, Lea said, “We can just
display a list of contents to consumers. All consumers have to do is to
choose what they want to hear or watch.”

In the new era of networked devices, most consumer electronics makers
have tossed aside the model of one powerful server as each home's sole link
to the outside world. And even though many remain skeptical of PC/TV
convergence products, LSI Logic's Dolan predicted that 1999 will be a year
of “experiments” for many system vendors to launch such combo boxes
as DBS/DVD, WebTV/set-top or DVD/WebTV.

“We think that two factors-cost savings and enhancement of consumer
functions-will drive consumer platform convergence,” said Les Kohn, a
fellow and chief architect at C-Cube Microsystems. He envisioned video
storage being integrated into DVD, digital-TV or WebTV boxes.
