Its future looks very sharp, but will DVD videoplayer replace your VCR?
By Steve Alexander / Minneapolis-St. Paul Star Tribune

There is a comic moment in the movie Twister when the heroine notices that her empty pickup truck has been blown away by a tornado. "Where's my truck?" she asks, and instantly it drops out of the sky.
Manufacturers and sellers of new DVD video players are hoping for similar instant gratification this holiday selling season. Having stirred up a whirlwind of publicity, they hope that cash will rain down from the sky.
But it remains to be seen how many consumers will embrace a technically superior $500 to $900 replacement for the $200 VCR.
DVD, an acronym for "digital video disk" or "digital versatile disk," uses a CD-ROM-sized disk to display films in stunning high-quality video and stereo sound. DVD's benefits are easiest to see and hear if consumers have a big-screen TV or a "home theater system."
DVD's main technical drawback is that it doesn't record as VCRs do. DVD units capable of recording appear to be at least three years in the future.
Hany Nada, a senior technology analyst at the Minneapolis brokerage of Piper Jaffray, says DVD is clearly superior to the VCR.
"It has a much cleaner, better-looking picture, more accurate sound reproduction and a more 'immersive' environment," he says.
DVD's picture and sound qualities come from a technique called "video compression," which squeezes up to 133 minutes of video and sound onto one side of a shiny disk. When the disk is played, the data is decompressed on the fly and displayed on the TV.
DVD picture and sound quality sometimes are compared to those of direct broadcast satellite transmissions, which also offer better-than-TV picture and sound through compression techniques. But Nada says DVD is better.
"DVD uses the same compression technology, but at a higher bit rate," the number of computer "bits" transferred to the TV per second, he says. "There is more information coming off the DVD player than comes off the direct broadcast satellite."
Besides near-theater-quality picture and sound, DVD allows consumers to "browse" through a video to watch favorite scenes. And, because DVD disks have large storage capacity, equal to 4.7 gigabytes of computer data per side, they have other capabilities not found in videotape.
For example, movies can be recorded with multiple soundtracks in different languages. They also can be recorded in multiple screen formats, such as full-screen or "letterbox," in which the uppermost and lowermost portions of the TV screen remain blank.
DVD technology also permits a feature called "parental lock," in which children can be prevented from watching certain scenes in a movie. As the capacity of DVD disks continues to increase, it will be feasible to record multiple versions of a film with different viewer ratings to accommodate varied consumer tastes.
But because DVD is new to the consumer market this year, no one expects it to replace the VCR overnight. The Consumer Electronics Manufacturers Association has projected sales of about 400,000 DVD video players nationwide this year, compared with 19.6 million VCRs. As a result, retailers are aiming their sales pitches at "early adopter" consumers who like new electronic gadgets so much they are willing to pay high prices for them. Mainstream consumers aren't expected to buy many DVD players until next year, after prices decline and the technology is more familiar.
Retailers are hoping DVD will be the next big consumer product.
As a business strategy, selling DVD disks is more attractive than selling videotapes because the profit margins are better, says Ed Goetz, president of Simitar Entertainment Inc., a Maple Plain, Minn.-based marketer of DVD disks and videotapes. While DVD development costs are higher than they are for videotape, those expenses will decline within a year, he predicts.
But while the growth potential of DVD is great, at least two obstacles could block its success:
A rival DVD video format to be introduced next year could make this year's DVD units obsolete by mid-1998. Fears of pending obsolescence might stall DVD video player sales this Christmas.
And the majority of U.S. consumers, accustomed to the quality and relatively low cost of VHS videotape, may not embrace DVD technology anytime soon. Because VCRs are in about 90 percent of U.S. homes, DVD industry experts say, it might take the better part of a decade for DVD to replace the VCR.
DIVX (digital video express), the rival format to DVD, appears to be an attempt by movie companies and one large retailer, Circuit City, to capture the video rental market now largely controlled by independent firms that buy a videocassette of a film once and rent it many times. Circuit City reportedly invested $130 million in companies developing the DIVX technology.
Unlike today's DVD disks, which can be bought for an average of $25 each and endlessly replayed, next year's DIVX disks would cost $5 to $7 but would be encoded with computer software that would render them inoperative after a short period, perhaps 48 hours. Consumers then could buy additional viewing of the disk through a DVIX player-to-telephone connection that would disable the encoding software temporarily.
The result: DIVX disks essentially would be movie rentals, but the rental revenue would go to the movie company that owns the film, not to a rental store. For an additional fee, consumers could gain the ability to view the DIVX disk an unlimited number of times, in effect converting a rental disk into a purchase.
Nada says DIVX represents nothing less than an effort to create a major economic shift in the film rental industry.
"The way it works now, a film company such as Warner or Disney sells a copy of a movie to a rental store for $100 to $200 a tape -- and that's all the movie company gets, even if the tape is rented many times," he says. "The DIVX standard is meant to push the rental stores out of business."
The problem for consumers is that DIVX disks cannot be viewed with the DVD players being sold this holiday season. If DIVX becomes the standard for DVD players, this year's DVD players will become instantly obsolete.
Whether DIVX will succeed or fall by the wayside is a matter of conjecture. Several movie companies, including Disney, have embraced DIVX but are hedging their bets by also producing standard DVD disks.
Ed Goetz, president of Simitar, predicts DIVX will be hurt by its late entry into the market and by a lack of support from most big DVD hardware retailers. "The retailers see DVIX as being a ploy on the part of Circuit City and Disney to eliminate the rental retailer," he says.
Tom O'Reilly, editor of DVD Report, a trade journal, says the fate of DIVX will depend on whether it reaches the market in mid-1998 as planned, whether it works properly and whether consumers become frustrated by the potentially complicated telephone link needed to buy additional movie viewing time.
"I think the odds are against DIVX," he says. "But even so, I would not risk spending my $500 on a DVD player right now."
Still, while no one knows the rate at which DVD will be adopted by consumers, proponents claim it will happen faster than the 10 years it took VCRs to gain widespread acceptance or the roughly seven years it took audio CDs to become widely used. They say the rate of technological change is accelerating and that as a result DVD will become a mainstream consumer product much faster.

The old story, Philips and Thomson fighting Toshiba, Sony, Hitachi, with plenty of backstabbing in between. The European launch of DVD begins in 1998, which can only be positive for the MPEG2 stocks.

Four billion francs is about US$666 million. Even if they are greatly overestimating, it's a lot of cash. What exactly are we talking about here? "Encoding machines"? To compress the signal for disc manufacture? Who makes Phillips' encoder chips?

Winter CES will see first in a planned lineup of more highly integrated, market-specific devices -- IGS bets big on TV-out-capable graphics chips

Anthony Cataldo

Las Vegas - IGS Technologies plans to offer two new families of graphics chips with TV-out capabilities early this year.

The announcement comes as OEMs craft designs for next-generation TV set-top boxes for the home and PC companies explore ways of providing TV output as a standard feature.

While consumer interest in browsing the Internet on the TV has been slow to start, the promise of wideband communications through cable boxes, plus the idea of providing higher-quality TV output from the PC, have attracted the attention of a number of chip companies.

IGS hopes to up the ante by introducing highly integrated devices for specific market segments along with software tools to get OEMs to market quickly. The company has a lot riding on its strategy. It has bet big that many consumers will eventually opt to use a TV over a monitor. At the same time, the company is facing stiff competition from larger competitors that either offer more generic TV-out devices, which interface to a separate graphics controller, or have bolted on TV-out capability to an existing graphics processor.

The CyberPro5000, which will be introduced here at the Consumer Electronics Show, builds on the company's existing CyberPro2000 product. It includes features geared specifically for non-PC boxes that incorporate Internet-access capabilities, including cable, satellite and WebTV-type boxes.

Beyond the PC

Like its predecessor, the 5000 integrates a 64-bit GUI accelerator with 200-MHz RAMDAC and has a special bus that allows it to interface to all major X86 and RISC CPUs at bus speeds up to 50 MHz without the need for a bridge chip. Several new features, however, better equip the device for non-PC Internet boxes, according to Mike Raghavan, senior director of marketing for IGS.

For one, the video receiver can accept and display simultaneous video inputs coming from an MPEG decoder, TV, DVD or camcorder. Once the signals have been received, the chip provides direct output for the major TV formats used throughout the world, eliminating the need for a separate frame-buffer memory, according to IGS.

"For broadcast quality, many people don't want to use a frame buffer because it degrades picture quality. You have to scale down then up again. We're doing a direct pass through," Raghavan said.

Another new feature is an optional digital audio engine that complies with the AC'97 specification, which requires a separate off-chip codec. The audio portion includes a microphone interface and stereo speaker out through an I2S interface, as well as FM and 32-channel wavetable synthesis.

Another option that the company is offering is the Macro-vision 7.01 encryption scheme for playback of DVD movies on a TV, a feature expected to be widely seen in DVD-ready PCs next year.

"One of the main driving forces of TV out is systems that will ship with DVD," said Ken Lowe, director of marketing for IGS competitor Chrontel Inc. (San Jose, Calif.), which introduced its first TV-out devices with Macrovision encryption in November. "Almost 100 percent of them will incorporate TV out," he said.

Unlike IGS, Chrontel is focusing exclusively on improving TV-out capabilities rather than trying to integrate the graphics controller on the same die. Chrontel has fastened a digital interface to its $5 TV-out encoders that links to graphics controllers from several vendors, such as 3Dfx, Nvidea, Chips & Technologies, NeoMagic, Trident and Cirrus Logic. "We want to set the bar for performance, so it makes it difficult for an OEM to desire the integrated approach," Lowe said. "One example is the continual and incremental improvements in text quality. TVs have limited bandwidth compared with a monitor, and limited resolution compared with a CRT. The difficulty IGS will have is penetrating as a graphics company."

Indeed, companies such as S3 Inc. and Trident have already announced graphics devices with TV-out capabilities. And Cirrus Logic recently announced its own NTSC/PAL encoders that accept data streams from a VGA controller or MPEG decoder.

Yet IGS argues it can provide better TV-out quality than its competitors with comparable graphics capabilities for little incremental cost above a standalone TV-out chip. The company's CyberPro5000 will be sampling in January for $15, with a price break for volume purchases by the end of the second quarter.

In February, the company will introduce its first 3-D accelerator with TV-out capability, the CyberPro 3000. That device, which is expected to cost from $15 to $20, will perform setup, rendering and texture mapping, and will process up to 1 million triangles per second.

No z-buffer

One notable feature of the graphics engine is that it does not need z-buffering.

"We can have more resolution with fewer megabytes, and we can also have more memory available for texture buffer," said IGS's Raghavan. "We don't spend all our time drawing the entire triangle; instead, only the portion that needs calculating is done on the fly."

To help OEMs in cutting their board-development time, IGS is also offering software-development kits for the 3000 and 5000 devices for porting to real-time operating systems. Written in C, the new tools will allow customers to port an embedded OS in anywhere from a few days to a few weeks, according to IGS.
