DVD - Technology Update

TAIWAN - Some R&D, main focus on system integration
Although patents and royalty issues are still bothering Taiwanese firms, most optical drive vendors have been developing or studying DVD technologies. However, the main focus of companies is on system integration.

Opto-Electronics & Systems Laboratories (OES) of the Industrial Technology Research Institute (ITRI), a Taiwan-based non-profit R&D organization, has developed a 2-speed DVD-ROM drive and a DVD player. The mechanical parts, including the loader, are supplied by Sanyo, and the MPEG-2 ASIC is supplied by LSI Logic.

OES will make the technologies available to the private sector. Charles Chang, manager of the marketing department, said companies receiving the technologies will still need to purchase key components, like servo motors and ASICs from foreign suppliers. Nevertheless, government research units and the private sector have been trying to develop key components in order to set up a DVD manufacturing infrastructure in Taiwan.

DVD follows in success of CD-ROM

Most contacted firms agreed that Taiwan can succeed in DVD-ROM drive production by adapting the CD-ROM industry model. AOpen's Sean Chang, associate director of sales department I, of the company's optical product business division, pointed out that in the past two months, major Japanese optical drive vendors have been putting more effort into the development of DVD drives than CD-ROM drives, leaving a gap that can be filled by aggressive Taiwan CD-ROM drive vendors. "This may in turn affect Taiwan's progress in the DVD drive line," said Chang.

Lite-On's Andrew Lee, product manager, said Taiwan has a good chance of thriving in the DVD era. "Taiwan has a lot of experience and technological backup to help bring costs down. The CD-ROM industry has been a good example of this."

Cooperation on DVD disk, STB development

Most major optical disk manufacturers, including Ritek, CMC and BTC, have been working, either by themselves or with foreign partners, on rewritable DVD disks. OES and the private sector, which includes Acer, Tatung and ADI, have joined forces to develop digital set-top boxes that can decode DVD signals. AOpen has a dedicated team with five R&D engineers that have been working with partners to develop DVD products. Chang said design and manufacturing technologies need to be more precise for DVD products than those for CD-ROM drives.

DVD lab to cater for all formats

In order to meet increasing demand for DVD, OES, an A-class member of the DVD Forum, has formed a DVD verification laboratory with the help of Japan-based Matsushita. The laboratory will start testing DVD players, DVD-ROM disks and DVD-ROM drives by August this year, and DVD-RAM media and drives by the year 2000. OES will eventually support all DVD applications, including video, audio, ROM, RAM and recordable formats under the standard formats defined by the DVD Forum.

Research body develops key components

To set up a DVD manufacturing infrastructure, Taiwan has been active in developing key components for DVD. OES has been developing pickup heads for 4-speed DVD-ROM drives. Actima, a B-class member of the DVD Forum, also plans to get involved in developing pick-up heads. Winbond and ALI have provided DVD source decoder ICs.

AOpen will probably not develop pickup heads or ASICs, but the company plans to develop a mechanism, such as a loader, for DVD-ROM drives. The company developed a loader for its 2-speed DVD-ROM drive, though the drive did not enter production. The company will first use Japanese components for its 4-speed or faster DVD-ROM drives, and try to develop its own loaders when volumes increase to an adequate level, according to Chang. "We are not a key component vendor, so developing pickup heads or ICs makes little sense."

Lite-On plans to ship a 4-speed DVD-ROM drive by the end of the year. The drive will integrate key components from Japan-based vendors. The company has no plans to develop key components. Lee pointed out that the company's focus was not on technology, but on manufacturing scales and meeting market demand. "Japanese firms have developed excellent components that we can integrate into good drives."

Makers launch several DVD products

Several companies, including Acer and Esonic, a portable video CD player manufacturer and an A-class member of the DVD Forum, have launched DVD players.

Raite, a B-member of the DVD Forum, has started to ship a 2-speed DVD-ROM drive, and plans to deliver a DVD player that supports six stereo channels in August or September this year. The company co-developed both products with a design company from Japan and purchased the components from major Japan-based DVD component vendors.

Bill Chang, president, said the firm plans to launch evaluation samples of a 4-speed DVD-ROM drive by September which will be ready for production in October 1998. Chang predicted that 4-speed DVD-ROM drives will boom in the third or fourth quarter this year. The firm also plans to release a slim DVD-ROM drive by the end of the year.

4.7G DVD version 2.0 may face delays

The DVD Forum plans to finalize specifications for the single-sided 4.7G DVD version 2.0 in October 1998. However, most contacted firms thought that the schedule might slip until some time next year.

AOpen has started to sell a SCSI-interfaced DVD-RAM drive that is made in Japan. The drive will be delivered with several DVD-RAM disks and a SCSI controller card. The company will be developing DVD-RAM drives complying with 2.0 specifications when available. Chang said the market for these drives will start to boom by the second half of 1999.

Lite-On has no immediate plans for DVD-RAM drives because of the lack of a standard and because the market is still immature.

Raite will develop a DVD-RAM 2.0-compliant drive after the standard is finalized. Chang said the most difficult part of the development will be the rewritable technologies. "How to develop the drives to provide good reliability and quality is the key factor."

DVD in Hong Kong. The land of the sub $300 DVD player...............

DVD - Technology Update

HONG KONG - DVD's success to outpace CD's
Hong Kong makers are touting DVD as the most important optical disk technology since CDs first appeared in 1983. After its arrival last year, DVD has received a lot of support from Hollywood's major movie studios and consumer electronics manufacturers worldwide. By its first anniversary, over 500,000 players and 5 million disks are expected to be sold, compared to just 35,000 CD players sold in 1983.

"DVD will mirror the development of CD technology in many ways, though at a much brisker pace, and output from makers will soon be large," said Anthony Budhrani, sales manager at Wing Cheong Electrical.

SMC Multimedia Products started producing DVD players in March this year. The company's home theater model, the DVD 330, features MPEG-2 digital image compression technology, multi-camera angles and supports up to 32 different language subtitles. This $280 model has a high-resolution 500-scan-line output and is compatible with both single- and dual-layer discs. By the third quarter of 1998, an advanced $320 version, the DVD 530, will hit the market, with Dolby's AC3 decoder for six-channel surround sound.

DVD offers greater capacity, enhanced features

Hong Kong makers are stressing the addition of extra features to their models, such as Karaoke functions. SMC's DVD 330 has multi-feature Karaoke with echo and volume control and supports a soundtrack with up to eight languages.

Current models offer a 500-line resolution on a TV, but makers hope to increase this to 800 lines soon.

Also: "Makers are moving toward double-layer, double sided DVDs, with a capacity of 10G and even 16G. This is perfect for epic-length movies or for storing both wide-screen and pan-and-scan versions on one side of a disc," said SMC's electronic engineer, Raymond Chan.

The potential scrambling rate of DVD can reach 96kHz as compared to 44.1kHz for standard audio CDs but currently this is restricted to 48kHz on released models. Wing Cheong's advanced DVD players combine AC-3 (Dolby Digital) full decoding, Dolby Pro-Logic decoding and Dolby Virtual Surround (Q surround) for theater-quality sound.

Common features on emerging models include elaborate multi-lingual on-screen displays for random access tracking of specific DVD chapters/titles, universal remote controls that allow step-frame, choice of slow motion, 2-, 8- and 30-speed searching and up to four times zoom capabilities, and up to eight alternate audio tracks.

Entertainment industry fuels DVD adoption

As with CDs, the mainstream entertainment industry and Hollywood are the main movers behind DVD. Computer applications that need enormous amounts of data like games will also encourage DVD development. "The interactive multimedia content of computer games has increased so much that multiple-disk CD-ROM games are common now -- they are prime targets for DVD technology," said SMC's Chan.

Title makers are using repurposing technology to reproduce CD-ROM titles as DVD titles. Digitized photo collections, large reference databases, atlases that require as many as nine CDs of storage space, and encyclopedias are seen as ideal candidates for this technology.

Limited titles biggest block to sales

Limited availability of titles has been the biggest roadblock to the uptake of DVD until now. However, software makers have now produced over 1,000 DVD movie and music titles for sale at retail outlets, with the figure expected to double by the end of 1998. With these volumes, prices of DVD titles are falling.

According to Chan: "While a Japan-made title was priced at around $65 last year, DVD titles from Taiwan and China are now available for just $2 to $5. In the United States, Warner Home Video recently finalized a new three-tier pricing plan, offering classic movie titles for just $9.95."

DVD players now CD-backward compatible

Makers claim new-generation DVD players are now backward-compatible, supporting all licensed copies of VCDs and audio CDs. SMC's models support formats like CDI movies, digital audio CD (CDDA), VCDs and even CD-R disks. "However, DVD players have problems running pirated VCDs," said SMC's manager for procurement and trade, Jackey Ho.

Makers cut costs, reduce size

Hong Kong makers are focusing on cutting costs and sizes of drives through the development of advanced software and a reduction of components. Available from Wing Cheong is a portable DVD player with a built-in LCD monitor called Dream Theater, which supports both VCD disks and audio CDs, in addition to new DVD-video disks. In the offing is another mini-size model with enhanced visual clarity through patented "Digital Gamma Correction" and "Digital Super Picture" software. A "color separate" output and a 10-bit image D/A converter improve picture quality.

SMC's R&D focus this year is on developing DVD players using DVD loaders to replace traditional DVD-ROM player lines. This will help slash costs, said Ho, and will enhance control of servo parts as well as reading accuracy.

Makers are also developing dual-lens, single-laser optical pick-up on DVD players. This feature consists of individual lenses optimized for spherical aberration to guarantee superior reproduction of DVDs, VCDs and CDs. This was not possible with dual focus hologram systems found in older DVD players.

Some makers are contemplating introducing blue laser technology to optimize storage capacity through shorter wavelengths.

Wu predicted that sales of DVD-ROM drives would surpass those of CD-ROM drives by the year 2000, and DVD-ROM drives will eventually become standard on all PCs. Meanwhile, DVD-ROM upgrade kits and DVD-equipped PCs from Hong Kong will be on store shelves next year, adding about $700 to $900 to the cost of a base system.
