The DVD Writer: Blu-ray Disc and the Meaning of Backwards Compatibility

Change is unsettling. But, like it or not, change is once again upon us—this time with the arrival of next generation Blu-ray Disc (BD). Naturally, consumers and even professionals are apprehensive about this new format but, even so, BD's promoters are doing an embarrassingly poor job of understanding and answering concerns. For example, manufacturers and content publishers amazingly have yet to clearly and consistently articulate BD device compatibility with CDs and DVDs.

What focuses my attention on this issue is a flurry of press releases distributed last week at the Consumer Electronics Show (CES) in Las Vegas. Proudly, some proclaim "Blu-ray Disc players will be fully backward-compatible with current CD/DVD formats" and others "Blu-ray Disc playback products are expected to be backward-compatible with the current DVDs, allowing continued enjoyment of existing DVD collections." Disappointingly, these statements are not as defining as they might at first appear but more reminiscent of the unforgivably slippery language used regarding DVD/CD compatibility when DVD was released ten years ago.

Now, as was the case then, backwards compatibility is not mandated by official specifications, so it's going to be a matter of choice for each individual hardware manufacturer. Thus, all marketers can claim is that it is possible to design BD devices that can read and write existing CD and DVD formats. They've made few efforts to clarify technical distinctions within and among the various disc families, and explaining how costs and market forces inexorably drive compatibility decisions hasn't seemed a priority.

Physical, application, and logical considerations are all part of the technological compatibility picture. On the physical level, CDs, DVDs, and BDs are distinctly different from one another. Supporting all of them in a single device is a considerable challenge. Each employs different-sized pits, lands, tracks, and substrate thicknesses. Each is composed of disparate materials and is written or read using lasers of various wavelengths through lenses of assorted numerical apertures. Each format's optical response is also carefully tuned so discs are not panchromatic.

Thus achieving physical compatibility requires BD players, drives, and recorders to incorporate involved optical pickups employing multiple lasers (780nm for CD, 650nm for DVD, and 405nm for BD) and numerous other clever tricks. DVD-RAM's oddball nature (not to mention optional cartridge) requires still further hardware modifications be made.

As such, expect an array of device permutations on the market. For example, set-top BD players that work with DVD±R/±RW but not CD-R/RW or DVD-RAM. Perhaps computer recorders that read/write DVD±R/RW but not CD-R/RW or DVD-RAM or set-tops that write DVD-R/RW/RAM but neither DVD+R/RW nor CD-R/RW. And there will even be some units that try to do them all.

Application and logical layers muddy these waters still further. Even if a device can physically read a disc, the hardware must be programmed to decode and interpret its contents. For example, while all BD units will most likely play standard DVD-Video (DVD-V) titles, can the same be said for discs of the DVD-Audio (DVD-A) or DVD Video Recording (DVD-VR) persuasions? What about Audio, Video, or Super Video (CD-DA, VCD, SVCD) CDs? MP3/WMA CDs and DVDs? And while I'm at it, will all BD units support DVD content protection systems including Content Protection for Recordable Media (CPRM) and the Video Content Protection System (VCPS)?

In fairness, the transition to any new storage format is traumatic and managing it a tremendous challenge. That said, the optical storage industry should not squander its opportunity to start fresh and clean up the messes they created in the CD and DVD formats. And universally launching entirely backward-compatible BD products would be a good start. At the very least, the industry should provide clear explanations of any limitations up front, and go on to use consistent marketing language to let everyone know what BD truly holds in store.

Hitachi's New DVD Camcorders Focus on a Host of User-Friendly Features

The Home Electronics Division of Hitachi America, Ltd., a subsidiary of Hitachi, Ltd.,, has introduced its sixth-generation UltraVision DVD Camcorders comprised of four new models offering new features for an affordable price.

The advances in Hitachi's new DVD camcorder line satisfy the demands of both tech-savvy users wanting cutting-edge, premium features and enhanced CinemaRes image quality as well as price-conscious consumers focused on convenience and ease of use.

The new product line, comprised of the DZGX3300A, DZGX3200A, DZGX3100A and DZBX35A, provides media format versatility to support the most popular and widely available DVD formats, including DVD-R, DVD-RW, DVD-RAM and DVD+RW discs as well as SD cards for digital stills. Other user-friendly features include a One Touch finalization button for quick and easy access to this essential last step, and a sleep/restart battery saver function that puts the camcorder in hibernation to save battery power between recordings and enables users to begin recording within one second of activation to ensure no action is missed.

All models include the new Video-to-Photo Frame Grab Tool, which allows users to pull a photo still from video and route to SD memory card. This prevents taking video without switching the "still mode" on and off and enables users to easily create the photo image of any desired scene after recording onto DVD. Additionally, all models offer enhanced Super Digital Zoom, a large 2.7-inch 16x9 widescreen LCD, and a "Quick Mode" Menu System that features Hitachi Disc Navigation to instantly access desired scenes via thumbnail images without having to fast forward or rewind.

Ranging from $399 to $799, the new models exceed Hitachi's goal of providing high-quality, cutting-edge technology at an affordable price. Superior imaging is made possible with the company's new CinemaRes Advanced Image Processing with "Oversampling" high resolution capture, an exclusive technology that uses the entire CCD to capture both video and still images before converting to DVD format, utilizing the camcorder's entire capacity to create a sharper, more detailed picture.

New this year, Hitachi introduces its first line of DVD camcorder accessories, including the CAMKIT2 that features a Hitachi-branded nylon camcorder bag, two-hour battery and three DVD-R discs, as well as the Hitachi Video Light, 2x Telephoto Zoom Lens, and a Media Pack with a mini DVD disc wallet.

Hitachi's top-of-the-line UltraVision DZGX3300A DVD Camcorder offers a 3.3 mega pixel resolution with a maximum photo resolution of 2016 x 1512 and 10x optical zoom. New to the line, this unit features a polished smoked-chrome finish and aerodynamic design for a dramatically contemporary styling. The DZGX3200A follows with 2.12 mega pixels at 1600 x 1200 and 10x optical zoom. Both models feature PC and Mac compatibility for the first time ever and include a powered accessory port (hot shoe) as well as Composite and S-Video Inputs. The DZGX3200A will be available in March for a suggested retail price of $599 and the DZGX3300A will be available in April at a suggested retail price of $799.

The UltraVision DZGX3100A DVD Camcorder sports a 1.3 mega pixel resolution at 1280 x 960 and 15x Optical Zoom and 800x Super Digital Zoom. The unit comes with a 700mAh slim battery that records for over an hour with the widescreen LCD open, Composite and S-Video Inputs, a USB 2.0 cable and PC and Macintosh compatibility. The DZGX3100A will be available in April at a suggested retail price of $499. With 680K pixel resolution at 640 x 480 and a 25x optical/1200x super digital lens, the UltraVision(R) DZBX35A rounds out Hitachi's DVD camcorder product line. Retailing at $399, the DZBX35A provides unprecedented value. The DZBX35A will be available in March.
