Divicom Debuts New Digital Video Encoder

By LESLIE ELLIS

Denver -- Divicom Inc. is set to take the wraps off a new digital video encoder today, targeted to optimize transmission bandwidth for broadcast, satellite and cable operators.

The new MediaView MV40 encoder, based on MPEG-2 DV silicon from Divicom's parent, C-Cube Microsystems Inc., includes a "look-ahead" capability that distinguishes it from other video encoders, said executives during a briefing here Feb. 13.

Tom Lookabaugh, president of Divicom, said the new feature means that potential customers "can save money by increasing the efficiency of their transmission bandwidth and increasing their revenue streams by offering more channels of programming over the same amount of bandwidth."

The "look-ahead" technology works by harnessing the power of two complete encoding chips, one of which keeps looking at the complexity of incoming content so that it can predict exactly how much bandwidth will be needed, said Ben Stanger, marketing manager of Divicom. The second chip actually encodes the material.

"Other encoders work by reacting to digitized content and taking more of an averaged approach to bandwidth prediction," he said. "This way, you optimize and manage available bandwidth by tracking it precisely."

Stanger said analog or digital content enters the encoder, it is processed by an adaptive field-frame decoder and it then moves through an adaptive preprocessor and noise reducer.

After that, about 16 frames of video at a time flow into a buffer, so that the first encoding chip can "look ahead" and determine the required bit rate. The second encoding chip then performs the actual encoding, with the appropriate bit rates, and the content is then passed off to a transport-stream-formatting and control chip before exiting the encoder.

The MV40 encoder is designed to work with Divicom's "MediaNode" statistical multiplexer, so that up to 32 encoded bit streams can be placed together.

Users of the encoder can specify minimum and maximum bit rates, from 700 kilobits per second up to 8 megabits per second, Stanger said.

The encoder will be commercially available early next month, at prices ranging from $55,000 to $70,000, executives said.

US West getting ready for DSL................................

U S West, Software Giants Team Up for High-Speed Data

By FRED DAWSON

The telcos continue to get serious about competing in the high-speed-data market.

U S West Communications last week enlisted the support of several computer-industry giants to help develop a next-generation data-network infrastructure that can exploit the full potential of high-speed access in the mass market.

U S West said agreements with Sun Microsystems Inc., Microsoft Corp., Hewlett-Packard Co., Digital Equipment Corp., Oracle Corp. and Novell Inc. would lead to implementation of software capabilities in the network that will foster development of services of every description, including IP (Internet protocol) telephony, electronic commerce and interactive multimedia.

The telco is building on its plans to offer DSL (digital subscriber line) access rates at 256 kilobits per second and higher in more than 40 cities by midyear.

At the same time, the company said it had expanded the reach of its data services outside of its telephone-operating territories. U S West will use long-haul fiber lines supplied by Qwest Inc. to connect to 25 markets, adding to 21 markets already covered in a long-line agreement with Williams Communications Inc. that was announced last month.

The two pacts give U S West access to 24,000 fiber optic miles for interconnecting out-of-region markets to services offered by the U S West Interprise Networking unit, officials said.

These long-haul lines all operate beyond U S West's territory, allowing it to avoid restrictions on entry into long-distance service.

More problematic is a request that the telco is weighing to the Federal Communications Commission for permission to operate long-haul data networks within its operating territory, on the grounds that this is the best way to ensure that rural communities will have access to Internet services, said John Charters, vice president of Internet services for the carrier.

U S West is using DSL equipment to extend high-speed-data services into the consumer and SOHO (small-office/home-office) markets within its 14-state operating territory, but it will stop there. The telco does not intend to exploit DSL capabilities outside of its territories, as it could under new options that are open to competitive local-exchange carriers, Chambers said.

"We don't believe that the folks in Florida have the first clue about who U S West is, but businesses there and elsewhere do, and that's where we're putting our focus," he said.

The company is using DSL hardware from Paradyne Inc. and NetSpeed Inc.

In many respects, what U S West is doing represents what could become a template for the telco approach to offering data communications in the residential market, as well as the business market. That's in contrast to the model being developed in cable, noted Kel Jones, manager of business development for Sun.

"What we're doing here represents for the telephone industry what the set-top initiative announced by TCI [Tele-Communications Inc.] and Sun last month represents for cable," he said.

The cable model focuses on the ability of the cable industry to derive revenues as both a media developer and a transport supplier. The infrastructure under development at U S West is aimed at drawing in as many developers as possible to expand the range of applications and, therefore, the network's ability to generate revenues. While U S West might get into some areas of content development itself, that is not on the plate at this point, Charters said.

"What we're doing in data is analogous to what we've done in voice, where we've used an array of adjunct processors in conjunction with the 5Es and DS100s [switches] to support provisioning of all kinds of services, including things like caller ID, three-way calling and voice mail, as well as more specialized services," Charters said. "We're creating an environment for third parties to write whatever applications they believe they can find a market for, much as Microsoft, Sun and Oracle have done."

While U S West's approach is typical of what can be expected from other telcos, the carrier is well ahead of the pack at this point, Jones said.

"We're talking to others that are in various stages of movement toward this model, but we've been involved with U S West over a much longer period of time, dating back to April of last year," he said.

A wide range of consumer services tied to the use of Sun's Java software language in a network-centric computing environment are moving rapidly toward commercial introduction, as was evident in a Sun display at the recent Consumer Electronics Show in Las Vegas. Products nearing rollout include Internet screen phones from Alcatel and Nortel; Internet set-top boxes from TV/COM, The Vestel Group, Sampo Corp., Network Computer Inc. and others; and a wide range of personal digital assistants and palm-top computers.

"We have between 400 and 500 companies developing applications in this space," Jones said. "Many of these entities are working on services that will use subscription or pay-per-view payment models."

DSL speeds will be too slow, at least in the near term, to support a full venue of video-entertainment services, Jones noted. But, he said, the Java-enabled devices now in the pipeline, in combination with the network capabilities developed by U S West, will create a platform for video-enhanced IP services that will complement services offered over cable.

"U S West will be able to go to the consumer and offer many of the types of interactive products that TCI and other cable companies plan to offer once they have their next- generation set-top boxes in place," Jones said.

What remains to be decided is whether the telco can build into the full-service consumer market from the interactive side sufficiently to head off the cable companies as they go interactive, he added.

Charters said U S West chose its software partners with an eye toward maximizing efficiency in customer use of its distributed-networking architecture, whether those customers are businesses linking their internal-communications networks, or businesses seeking to develop services for end-users.

"We picked our partners that have market-leading positions in the product areas that are important to us," Charters said.

The partners fit into different layers of the network, with Novell supplying the fundamental directory-enabled network platform that's required to manage the entire applications portfolio. This entails providing a single log-in capability in such key areas as directory, domain-name server, proxy cache, secure Internet, remote Intranet access and, with other components from other partners, site blocking and virus scanning.

"We're taking a lot of the confusion out of network utilization by turning to a single supplier," Charters said. "If newer technologies come along that we want to exploit, we can add them later."

DEC and H-P are key suppliers with respect to enabling the delivery of subscription products, Charters noted. DEC will work with U S West to integrate business customers' existing proprietary networks into the national IP-based network and to develop virtual private-network services; H-P, through its VeriFone subsidiary, will develop support for transactional services using smart-card, electronic-cash and related technologies.

The agreements with Oracle, Microsoft and Sun are meant to facilitate development of specific applications. In the case of Microsoft, it entails Windows NT-based development of IP voice, fax, video and conferencing, as well as e-commerce and traditional Web applications such as chat and e-mail.

The Oracle and Sun pacts are aimed at putting the network-centric/thin-client capabilities of those companies' software products to work across a vast array of applications, many of which are targeted toward the development of consumer services that will directly compete with services offered by the cable industry.

Lucent getting into LMDS equipment business:-)...................

VENDORS STILL BULLISH ON LMDS DESPITE TEPID BIDS IN AUCTION

By FRED DAWSON

The wireless-broadband sector last week remained a study in contrasts, with the LMDS auction getting off to a tepid start amid a surge in vendor support for the new technology that included Lucent Technologies Inc.

All but a handful of the major telecommunications players passed on a chance to acquire licenses to the biggest block of spectrum ever offered by the Federal Communications Commission. It was clear that the growing enthusiasm for the potential of wireless broadband among vendors had not convinced most operating companies that they could peg their future in local broadband communications to LMDS (local multipoint distribution service).

Instead, after the first day's first round of bidding, the overwhelming leader -- with $135.8 million bid on about 110 million "POPs" (units of population) -- was a nonoperating entity backed by major venture-capital firms and former Providence Journal Co. president and chief operating officer Trygve Myrhen, known as WNP Communications Inc.

U S West Communications -- one of two Baby Bells in the running, along with SBC Communications Inc. -- was a distant second, with $7.9 million bid on the 150-megahertz B-block spectrum, covering about 35 million POPs. SBC wasn't in the top 10.

In all, the first round drew bids of $192.6 million, 89 percent of which went for the 1.15-gigahertz A-block segments. Continuing uncertainty about the new technology was reflected in Comcast Corp.'s last-minute decision to pass on the bidding after having initially filed as a potential participant.

"After looking further at the options, we were all pretty well convinced that the technical capabilities were still to be determined," said Joe Waz, vice president of external affairs and public-policy counsel at Comcast.

While it's still early, it was clear that the bidding had a long way to go if it was to live up to various projections suggesting that the spectrum was worth as much as $4 billion.

For example, WNP was the top bidder for the 1.15-GHz A-block in the top eight BTAs (basic trading areas), offering $1.23 per POP. But the company with the most high bids -- Teligent LLC affiliate AUCO Inc. -- was first in 74 markets with total bids of only $2.9 million, representing only seven cents per POP.

While such numbers may not bode well for a big government take, they don't necessarily spell trouble for LMDS, said Dan Ernst, analyst with The Strategis Group. That company has been bullish on LMDS, with projections suggesting that the sector could generate annual revenues of $7 billion by 2007, with cumulative capital spending by that time of about $8 billion.

A press release issued by Strategis in October said total bids for the 493 BTAs "should bring in over $4 billion," with dense urban markets going for as much as $25 to $30 per POP. But Ernst insisted that the company's research had only suggested that the value of the spectrum was $4 billion, and not that $4 billion would be bid.

"The real success of LMDS will depend on whether the markets get built out," Ernst said. "The less that's paid for spectrum, the higher the probability is that this will happen."

Moreover, Ernst noted, the real state of affairs won't be clear until about two months after the auctions are completed and the winners begin to form partnerships. Also, he said, it would take a while to determine the true ownership of some participants, which could well turn out to be shell companies with major backing from large telecommunications players.

This possibility was on the mind of FCC chairman William Kennard. FCC rules bar local-exchange carriers and cable companies from holding more than 20 percent interest in A-block spectrum in their territories. But he's afraid that those companies will find loopholes in the FCC's rules to wield power over how LMDS licensees use the spectrum.

"If, for example, an incumbent [operator] holds 20 percent-ownership interest and, in exchange for financing an LMDS venture, it also holds options to acquire additional equity of up to 80 percent more, the investor's ability to affect the competitive nature of the venture would not be significantly different than if it had direct control," Kennard said.

A United States Telephone Association spokesman said the group was leaning against appealing a federal appeals court decision upholding the ban.

But Mary McDermott, the USTA's vice president of legal and regulatory affairs, noted that the group had circulated a letter among key members of Congress in hopes of generating support for its position that those restrictions are not consistent with the Telecommunications Act of 1996.

"We're resigned to the fact that where LMDS is concerned, we're really out of it," McDermott said. "Our goal now is to prevent this sort of thing from happening in the future."

The emergence of Lucent as a system supplier in LMDS and other wireless-broadband segments should help to ensure that LMDS systems will get built, with or without big telecommunications players, Ernst said, noting that such suppliers traditionally have supplied financing to their customers.

Gary Bonhan, a spokesman for Lucent, said such financing was a possibility, depending on "the particular situation."

Lucent said it had agreed to acquire the LMDS wireless business of Hewlett-Packard Co., and that it would launch a new wireless-broadband-networks division in Milpitas, Calif.

"We're not ready to announce a product at this point, but we expect to be able to meet market needs as they develop this year and beyond," Bonhan said.

Other vendors that have shown enthusiasm for wireless broadband include Nortel, Ericsson Inc., Siemens Telecom Inc. and Bosch Telecom Inc.

Nortel, which recently acquired wireless-broadband technology supplier Broadband Networks Inc., has taken an early lead in the market as the end-to-end supplier for many of Teligent's 700 markets, in a deal valued at $700 million.

Sources said Teligent was seeking a second major supplier, which was said to be a factor in Lucent's decision to jump into the market.

Also joining the supplier lineup last week was Ericsson, which said that it decided to develop its own system, rather than acquiring someone else's. Like the other suppliers, Ericsson said it was tapping the big breakthrough in monolithic-microwave integrated-circuit radio design of the past two years that has allowed developers to make very small solid-state transmitter/receivers for use in transmitting interactive broadband signals on a point-to-multipoint basis over distances of two to three miles.

Lucent -- also using the MMIC technology and, like many others, relying on over-the-air adaptations of ATM (asynchronous transfer mode) as the transport-and-access method -- will be able to quickly integrate the radio-access technology into its other transport-and-switching components, Bonhan said.

"There's nothing that has to be invented here to allow our customers to make use of all of the equipment that you need to build a complete network," he said.

Some smaller vendors were joining the field, as well, including radar-systems supplier BEL-Tronics Ltd. of Mississauga, Ontario, and PCS-wireless-systems (personal communications services) company Wytec Inc. of Santa Clara, Calif. BEL-Tronics, which has been acquired by San Diego-based investment firm Akcess Pacific Group, believes that it has found a way to deliver lower-cost transceivers than other suppliers, said Drew Smith, a consultant to the company, who declined to go into details.

Wytec, unlike most suppliers, is focusing its initial product on one-way delivery of video services, while offering a migration path to two-way later on, said Margarate Ralston, executive director for North American programs. The company is also developing gear for other spectrum tiers all the way to 42 GHz, she said.
