updated Another year, another global battle for tech supremacy. For most consumers, the decision whether to go with a plasma or LCD television is difficult enough. But consumers are now faced with the tough choice of two competing, next-generation DVD standards -- Blu-ray and HD DVD.

With the release of the

One of the problems is that Blu-ray and HD DVD formats are incompatible -- that means your Blu-ray player won't play HD DVD movies, and your HD DVD machine won't be able to read Blu-ray movies. There is currently one player on the market that will play both, but as with many players which are first to market it's been plagued with reports of compatibility problems.

No matter which format you choose, the new players aren't exactly what you'd call 'cheap', and the last thing any consumer wants to do is buy a machine that becomes obsolete in favour of another incompatible format.

So which format is worth your hard earned cash? What are the technical differences between the two? What products are available right now? And what do the editors here at CNET.com.au recommend? Read on for everything you need to know about the Blu-ray vs HD DVD battle.

FAQ: Is Blu-ray/HD DVD for you?

[? template("/cnet/livery/storyfragments/feature/bluray_hddvd.htm"); ?]

1. Blu-ray and HD DVD: what's all the fuss about?
Amidst all of the hype surrounding next-generation DVD formats, you may be asking yourself one simple question: what's all the fuss about? After all, your current DVD player produces a pretty good picture, right? Are Blu-ray and HD DVD really worth bothering about?

The short answer to that question is yes, Blu-ray and HD DVD do deserve your consideration -- but not necessarily your money (not yet, at any rate). The long answer is a lot more complicated, and involves other considerations such as your current home theatre set-up, the limited availability of movies and more (questions we'll get to later in this feature). For now, the fact that Blu-ray/HD DVD are to DVDs what DVDs once were to VHS means it is important for any prospective home theatre shopper to know exactly what the pros and cons are.

2. What's the difference between Blu-ray/HD DVD and normal DVDs?
The major difference between Blu-ray/HD DVD and DVDs is capacity -- that is, both Blu-ray and HD DVD can store more information than current DVDs on the same size 12cm optical disc we're all used to.

Without getting too technical, the reason for the increased storage has to do with the type of lasers used. DVDs (and CDs) use a red laser to read and write data to and from a disc. Blu-ray and HD DVD both use a blue laser, which has a shorter wavelength than red ones. The shorter wavelength, coupled with improved lenses, results in a smaller beam enabling a higher amount of data to be written to each disc.

DVDs can store around 4.7GB worth of data on a single side (8.5 for a dual layer DVD). In contrast, HD DVDs can store up to 15GB on a single layer while Blu-ray can hold 25GB on one layer. Even more can be packed into Blu-ray/HD DVD discs if they use more than one layer or one side of the disc.

3. OK, so Blu-ray/HD DVD discs hold more stuff. What does that mean for me?
More capacity means more information can be stored on each Blu-ray or HD DVD disc. In entertainment terms, that means full high definition movies or shows can be stored on a disc -- something previously impossible with DVDs (which only stores its content in standard definition). The greater capacity also improves the audio experience thanks to the ability to include more sound formats and, in some cases, uncompressed surround sound. The bottom line is Blu-ray and HD DVD movies and television shows look and sound much better than what is currently being produced by DVDs.

The added capacity, plus the added power of Flash, has also resulted in new functionality appearing on Blu-ray/HD DVD movies. For example, in standard DVDs users have to stop playback of a movie if they wanted to look at the DVD's menu. Blu-ray and HD DVD movies allows users to dynamically interact with the movie menu while watching it.

From the home office/home computer side of things, the higher capacity on Blu-ray and HD DVDs mean just that -- the ability to store much more data on a single disc. Entire hard drives worth of information can easily be backed up using just one next-generation disc.

You'll need a high-definition television to make the most out of Blu-ray/HD DVD.

4. What other home entertainment gear will I need to make the most out of Blu-ray/HD DVD?
It all sounds peachy so far, but here comes the first (and probably biggest) caveat -- to make the most out of what Blu-ray and HD DVD have to offer, you'll need some fairly up-to-date home entertainment gear, particularly a high definition television.

A major part of what made DVD an overnight success was the fact you could plug a DVD player into any television and immediately see improved visual quality. Don't expect the same to occur with Blu-ray/HD DVD -- if you have an old analog set (or even a newer flat-screen plasma or LCD with fairly low resolution) the picture Blu-ray/HD DVD delivers won't look much better than what DVD will produce.

Here's the minimum we recommend you'll need to be happy with Blu-ray/HD DVD: a decent 5.1 surround sound system, a flat-screen plasma or LCD with the capability to display 720p pictures at minimum, and at least one HDMI connector.

5. Why are there two competing formats in the first place?
The two formats -- Blu-ray and HD DVD -- were developed separately over many years, with Sony spearheading the Blu-ray camp and HD DVD championed by Toshiba. Both formats were competing for official recognition by the DVD Forum as the successor to DVD -- a battle which Toshiba eventually one. However, Sony and its partners decided to persevere with their invention, and hence the format wars began. Though there were several attempts to unite the two factions, they were unsuccessful -- and hence the difficult choice was instead passed on to consumers.

6. Which format is better?
Ask anyone from either the Blu-ray or HD DVD and they'll happily spruik about how their format is the superior one. The bottom line is both technologies have their strengths and weaknesses -- read on to find out what those pros and cons are.

7. So what Blu-ray/HD DVD products are available?
Blu-ray and HD DVD have landed in Australia, and at present there's at least a dozen lurking in a store near you. Standout devices so far have included the Sony PlayStation 3 and the Pioneer BDP-LX70 for Blu-ray and the Toshiba HD-XE1 for HD-DVD.

Several laptops have also included HD disk playing as an option from Toshiba and Sony. For a full list of the available players so far, click here.

Want to see at a glance what each format has to offer? Check our table below for more information.

As you can see below, while both Blu-ray and HD DVD offer much more than plain old DVDs, the differences between the two technologies aren't that pronounced. In terms of technology, Blu-ray can currently store more on a single side of a disc than HD DVD -- although double-sided, dual-layer and even other disc combinations coming in the future could see that storage difference become academic. Blu-ray can also currently output to 1080p -- most HD DVD units now output at 1080i, but the latest Toshiba HD-XE1 is able to display 1080p.

Notes

1. Each movie studio may choose to implement the image-constraint flag (HDCP)on a disc-by-disc basis, which constrains or down-converts the movie's resolution to 960x540 via the component outputs (HDMI output remains at full resolution). However, most major studios -- Sony (Columbia/Tri-Star/MGM), Fox, Disney, Paramount, and Universal -- have publicly stated that they will not make use of the image-constraint flag, at least initially. If true, movies from those studios will display at full resolution via the component outputs.

2. Video capacity will vary depending upon the type of encoding used. Discs encoded with MPEG-4 or VC-1 offer better compression and, therefore, more video per gigabyte (standard-definition or high-definition) than those encoded with the older, less efficient MPEG-2 codec.

3. All HD DVD and Blu-ray players should incorporate built-in audio decoding and analog audio outputs. Those features should enable the newer Dolby TrueHD, Dolby Digital Plus, and DTS-HD surround formats to be heard by using existing A/V receivers and audio equipment -- but the resulting soundtrack may be a down-mixed Dolby Digital or DTS-EX version that lacks the theoretically better audio fidelity that's encoded on the disc.

4. Manufacturer and studio support is subject to change. With the exception of Sony's devotion to Blu-ray and Toshiba's to HD DVD, other manufacturers and studios can (and already have) switch sides, or they can support both formats. Also, the depth of support for companies aside from Sony and Toshiba has yet to be determined; while some have already released single-format players, "support" for both formats has largely been limited to press releases or future product schedules and remain theoretical until they are available for purchase.

5. Early-generation set-top (non-PC) HD DVD and Blu-ray players are players only, with no recording capabilities. Future set-top recorders are expected to become available in both formats in 2008 or later, but look for copy-protection and digital rights issues to severely restrict the HD programming you'll be able to record from TV.

6. Managed copy refers to the ability to make an HD DVD or Blu-ray movie viewable via a home network or a portable video device. The details haven't been worked out yet, leaving managed copy as more of a theoretical option than a usable feature for the foreseeable future.

7. It is likely that HD DVD and Blu-ray will feature additional copy-protection methods (including Macrovision or other protections for analog outputs) than the ones listed here.

8. As of autumn 2006, HD DVD discs and players are not region-coded, but that could be changed at any point in the future -- for example, the appearance of region-coded discs and a firmware upgrade for the hardware needed in order to play them. Blu-ray discs are coded to three regions (roughly, the Americas and Japan; Europe and Africa; and China, Russia, and everywhere else not included in the previous two regions) that are far more streamlined than the nine-region DVD system. That said, HD DVD and Blu-ray players should honour the nine-region system when playing standard DVDs -- so don't expect to play out-of-region discs.

The case for Blu-ray

[? template("/cnet/livery/storyfragments/feature/bluray_hddvd.htm"); ?]

Blu-ray upside

  • High capacity
  • Can output to 1080p
  • Widespread industry support
  • Comes in the PlayStation 3 as standard
  • Backwards compatible with DVDs and CDs

Blu-ray downside

  • More expensive than HD DVD players
  • Top of the line gear needed to make it shine

Capacity
Blu-ray, the brainchild of Japanese giant Sony and backed by more than 90 member companies of the Blu-ray Disc Association, has the edge over HD DVD when it comes to storage, at least when you're talking about a single layer on a disc. Blu-ray can store 25GB on a single layer -- HD DVD can only store 15GB. The whole capacity issue is blurred somewhat when you move beyond single layer discs, however. Dual layer, triple layer, double sided and even quad-layer discs are in the pipeline for both formats, which means capacity can and will vary greatly.

1080p output
1080p is the best image that's possible with consumer entertainment devices today -- and the image quality is, frankly, stunning and almost 3D-like. 1080p delivers a resolution of 1920x1080 at up to a 54MBit/sec bandwidth -- and to to put it into perspective, normal DVDs output at 576p, while the highest HD signal in Australia only comes out at 1080i (for more about screen resolutions, click here). While the software in most current HD DVD players can only display at 1080i resolution, we expect 1080p technology to become more widespread in future players.

Widespread industry support
The Blu-ray camp has long claimed that its industry support from both hardware and content providers is superior to that of its competitor, HD DVD. The situation isn't so clear cut today as it was last year, however, as many companies have stated that they were willing to support both formats and not just one. Blu-ray's list of supporters is still longer than HD DVDs, but not by much.

On the content side of things, all Hollywood studios bar Universal and Paramount have pledged to release movies in the Blu-ray format. On the hardware side, Blu-ray is backed by Apple, Dell, Hewlett Packard, Hitachi, LG Electronics, Mitsubishi Electric, Panasonic (Matsushita Electric), Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson.

Sony Playstation 3

Comes in the PlayStation 3 as standard
Gaming could be the dark horse here in deciding which standard will reign supreme. After all, Sony's inclusion of the then fledgling DVD format in the PlayStation 2 did wonders for that format. All PlayStation 3s come with a Blu-ray drive as standard, and as a result it is the highest-selling player of either standard.

PS3's aren't exactly be cheap, however. The retail price is still set at AU$999 for the next-generation games console, while its Wii and Xbox 360 competitors hover at the AU$400 mark. The price may be high, but it's still pretty cheap for a games console and next-generation DVD player in one.

Backwards compatible with DVDs and CDs
Blu-ray devices have been designed to be backwards compatible with both DVDs and CDs, so there should be no problem playing your old collection of movies and music.

More expensive than HD DVD players
With only a couple of HD DVD players available in Australia at the moment, it appears that unless you but a PS# you'll end up spending more on a Blu-ray player. However, as the competition heats up there's bound to be price-cuts in place before the end of 2007.

It's a different situation when it comes to the notebook-based players, however. The Blu-ray-equipped Sony VAIO VGN-AR18GP is the same price as the HD-DVD-bearing Toshiba Qosmio G30 -- AU$5499.

Top of the line gear needed to make it shine
Forget about plugging a Blu-ray player into a CRT or older flat-screen panel -- you're going to need a display that can display at least 720p images to be happy with what Blu-ray can produce. And if you want to take full advantage of its image capabilities, you'll need a 1080p capable screen -- those screens are still very expensive compared to 720p models.

The case for HD DVD

[? template("/cnet/livery/storyfragments/feature/bluray_hddvd.htm"); ?]

HD DVD upside

  • High capacity
  • Widespread industry support
  • Cheaper prices for players
  • "Twin disc" support
  • Backwards compatible with DVDs and CDs

HD DVD downside

  • Many players limited to 1080i resolution
  • Console support only in the form of an Xbox 360 add-on

High capacity
HD DVD may not be able to pack in as much on a single layer compared to Blu-ray, but it's still a leap over what DVDs can manage. Single layer HD DVDs can store 15GB of information, with dual layer discs (at 30GB) already available. Other permutations of discs are also in the works (such as double-sided, triple-layer and more), with capacity stretching out to as much as 60GB on one HD DVD disc.

Widespread industry support
Toshiba, the developers of the original DVD specification and the driving force behind HD DVD, may not have as extensive a list of backers behind their new format as Sony does with Blu-ray, but the list is impressive nonetheless. Importantly, the gap in numbers of hardware and software supporters is diminishing every month. On the hardware side, HD DVD has the backing of industry giants like Microsoft and Intel. The list also includes LG, Thomson/RCA, Hitachi, TEAC, Kenwood, Onkyo, Fujitsu, Samsung, Sanyo, HP, NEC, Toshiba, Canon, Ricoh, Maxell, Acer, Lenovo and Imation. On the software side, HD DVD is supported by Paramount, Studio Canal, Universal, Warner, the Weinstein Company, Dreamworks and New Line.

Cheaper prices for media and players
Toshiba claims the fact that HD DVD can use the same manufacturing plants as DVDs (Blu-ray needs manufacturing plants built from scratch) is the major reason why HD DVD players will be cheaper for consumers. However, recent reports from the US have suggested that the difference in manufacturing costs are now minimal. On the hardware side, Toshiba currently sells the cheapest player on the market -- the Toshiba HD-E1.

"Twin disc" support
Unique to the HD DVD format is a "twin disc" capability, which allows both HD DVD content and DVD content to be imprinted on the same disc. Twin discs are HD DVD on one side and normal DVD on the other, which allows them to be played on both HD DVD players and DVD players. At the moment, however, none of these disks are available in Australia.

Backwards compatible with DVDs and CDs
Just like Blu-ray, HD DVD players will be able to read and play DVDs and CDs, which means your existing collection of movies and music won't become obsolete overnight.

Most players max out at 1080i resolution
1080i is the same standard as the Channel Nine and Ten HD TV feeds in Australia. While it's not as big a difference between 1080i and 576p (normal DVD resolution), the lower specification means HD DVD will be compatible with more flat-screen televisions. A minimum display capability of 720p is probably ideal, however. The second generation of HD DVD players -- which are starting to appear -- are capable of outputting at 1080p.

Xbox 360

Game support only in the form of an Xbox 360 add-on
As we saw with the inclusion of DVD in the PlayStation 2, the appearance of an emerging technology format on a games console can do wonders for the uptake of said format. While Blu-ray has the advantage (in gaming terms at any rate) of being standard on the PlayStation 3, HD DVD doesn't have the same level of gaming support. While Microsoft's Xbox 360 features an add-on HD DVD attachment, no games are currently available in the format.

Look before you leap

[? template("/cnet/livery/storyfragments/feature/bluray_hddvd.htm"); ?]

Getting caught out on the wrong side of Blu-ray vs HD DVD battle isn't the only thing you should be worried about when considering a next-generation DVD player. Here are a few more points CNET.com.au thinks you should consider before plonking your money down for either a Blu-ray or HD DVD device.

Where's the wow?
Sure, Blu-ray and HD DVD produce superior pictures tto DVD, but is it really that much of a leap? The opinion of most CNET.com.au editors here is that while the pictures produced by Blu-ray and HD DVD are impressive, it's not as big a leap as we experienced when seeing DVD compared to VHS for the first time. Our advice is for prospective buyers to see normal DVD pictures side-by-side to Blu-ray/HD DVD images before making a purchase -- after all, the last thing you want is to be unimpressed by the picture quality of your new player. If you're concerned about making the wrong choice then investing in a upscaling DVD player may be a better option in the short term -- just until this 'war' sorts itself out.

Copy protection from hell
If you thought the rights management on digital music was restrictive, just wait until you step into the next-generation DVD world. The companies behind Blu-ray and HD DVD have worked very closely with Hollywood studios to ensure copy protection was an integral part of both the hardware and software behind the new formats. Built into both formats is the option to lower the resolution of a movie if it isn't running over an HDMI cable (which conforms to strict copy protection measures). Blu-ray and HD DVD players can constrain an image down to 960x540 if the signal is going over a component cable -- still better than DVD but nowhere near the full capabilities of Blu-ray/HD DVD. That means consumers with older sets (those without HDMI) could find their viewing hamstrung if the movie studios decide to use this feature on upcoming next-gen releases. Thankfully, most of the studios -- Sony (Columbia/Tri-Star/MGM), Fox, Disney, Paramount, and Universal -- have publicly stated that they will not make use of the image-constraint flag, at least initially.

Shifting industry support
The lines between those in the Blu-ray and those in HD DVD camp are shifting on a seemingly daily basis, as companies on either side of the fence can and will switch sides if the going starts to get rough. In the past year, we've already seen several Blu-ray/HD DVD stalwarts switch sides or declare their allegiance to both formats -- expect more in the coming months after the Paramount announcement.

Some people may not think the 'wow' factor a Blu-ray/HD DVD player provides is enough to justify the cost.

Early adopter price gouge
We early adopters have a tough cross to bear. Sure we get the latest and greatest, but we usually have to pay through the nose for it. If either of these two formats take off, expect to see massive price reductions in players within a year. Buyer's remorse, anyone?

Where are the recorders?
Current Blu-ray/HD DVD home entertainment units are players only -- so you'll have to buy a notebook or PC to get a next-generation DVD that you can record to. If you want to record HD television, you need to wait until Blu-ray/HD DVD set-top recorders come out in 2007

Miniscule movie list
In order to kickstart sales of their players, manufacturers have been bundling disks and redemption vouchers with their Blu-ray/HD DVD devices -- with up to five in a box!. Australia is slowly catching up with the US in terms of available titles, but buying online from the US is probably the only way you'll be able to find next-generation DVDs. Fingers crossed a flood of movies arrives on our doorstep sometime before Christmas.

Going universal
The theory goes like this: These are both just optical discs after all; why can't someone create a universal player that plays both? Buy that player and build your movie collection with impunity. Samsung is still reticent on details for on its BD-UP5000 universal player, but LG recently brought its BH100 to the market. However, one problem that the BH100 has is that it lacks support for HD DVD's HDi format -- meaning no interactive menus or advanced features while watching HD DVDs. But we're hopeful that this trickle of machines will one day become a flood -- if more companies can provide combo players, the format war could quickly turn into a peaceful coexistence.

Who needs discs anyway?
We're going to get all future-focused here, but who says disc formats are the way to go anyway? Online delivery of HD content may not exactly be a reality in Australia yet, but who knows what the scene will be like in two or three years time? If everything's being delivered via the Internet and stored in our big home backup drives, who needs optical discs?

Blu-ray and HD DVD products in Australia

[? template("/cnet/livery/storyfragments/feature/bluray_hddvd.htm"); ?]

The first products off the rank weren't dedicated home theatre units, but laptops -- both Toshiba and Sony packaged their high-end notebooks with next-generation DVD devices. Over the course of the last year, dedicated players have started to appear on the market. Below you'll find a selection of the Blu-ray and HD DVD devices which have been through our labs.

Meanwhile, we here at CNET.com.au would love to hear about your experiences with next-generation DVD. Are you happy with your purchase? Which players/units did you buy? What made you choose either Blu-ray or HD DVD? And if you're sitting on the fence, we'd like to hear from you too.

HD DVD (short for High Definition Digital Versatile Disc)[1] is a discontinued[2][3][4][5] high-density optical disc format for storing data and playback of high-definition video.[6] Supported principally by Toshiba, HD DVD was envisioned to be the successor to the standard DVD format.

On February 19, 2008, after a protracted format war with rival Blu-ray, Toshiba abandoned the format,[7] announcing it would no longer manufacture HD DVD players and drives.[6] The HD DVD Promotion Group was dissolved on March 28, 2008.[8]

The HD DVD physical disc specifications (but not the codecs) were used as the basis for the China Blue High-definition Disc (CBHD) formerly called CH-DVD.

Because all variants except 3× DVD and HD REC employed a blue laser with a shorter wavelength, HD DVD stored about 3.2 times as much data per layer as its predecessor (maximum capacity: 15 GB per layer compared to 4.7 GB per layer).

History[edit]

In the late 1990s, commercial HDTV sets started to enter a larger market, but there was no inexpensive way to record or play back HD content. JVC's D-VHS and Sony's HDCAM formats could store that amount of data, but were neither popular nor well-known.[9] It was well known that using lasers with shorter wavelengths would yield optical storage with higher density. Shuji Nakamura invented practical blue laser diodes, but a lengthy patent lawsuit delayed commercial introduction.[10]

Origins and competition from Blu-ray Disc[edit]

Sony started two projects applying the new diodes: UDO (Ultra Density Optical) and DVR Blue together with Philips, a format of rewritable discs which would eventually become Blu-ray Disc (more specifically, BD-RE) and later on with Pioneer a format of read only discs (BD-ROM).[11] The two formats share several technologies (such as the AV codecs and the laser diode). In February 2002, the project was officially announced as Blu-ray Disc,[12] and the Blu-ray Disc Association was founded by the nine initial members.

The DVD Forum (chaired by Sony) was deeply split over whether to go with the more expensive blue lasers or not. Although today's Blu-ray Discs appear virtually identical to a standard DVD, when the Blu-ray Discs were initially developed they required a protective caddy to avoid mis-handling by the consumer (early CD-Rs also featured a protective caddy for the same purpose.) The Blu-ray Disc prototype's caddy was both expensive and physically different from DVD, posing several problems.[13] In March 2002, the forum voted to approve a proposal endorsed by Warner Bros. and other motion picture studios that involved compressing HD content onto dual-layer DVD-9 discs.[14][15] In spite of this decision, the DVD Forum's Steering Committee announced in April that it was pursuing its own blue-laser high-definition solution. In August, Toshiba and NEC announced their competing standard Advanced Optical Disc.[16] It was adopted by the DVD forum and renamed to HD DVD the next year.[17]

The HD DVD Promotion Group was a group of manufacturers and media studios formed to exchange thoughts and ideas to help promote the format worldwide.[18] Its members comprised Toshiba as the Chair Company and Secretary, Memory-Tech Corporation and NEC as Vice-Chair companies, and Sanyo Electric as Auditors; there were 61 general members and 72 associate members in total.[19] The HD DVD promotion group was officially dissolved on March 28, 2008, following Toshiba's announcement on February 19, 2008 that it would no longer develop or manufacture HD DVD players and drives.

Attempts to avoid a format war[edit]

Main article: High definition optical disc format war

Much like the videotape format war between VHS and Betamax, HD DVD was competing with a rival format, Blu-ray Disc.

In an attempt to avoid a costly format war, the Blu-ray Disc Association and DVD Forum attempted to negotiate a compromise in early 2005. One of the issues was that Blu-ray Disc companies wanted to use a Java-based platform for interactivity (BD-J based on Sun Microsystems' Java TV standards), while HD DVD companies wanted to use Microsoft's "iHD" (which became HDi).[20] Another problem was the physical formats of the discs themselves.[21] The negotiations proceeded slowly and ultimately stalled.[22]

On August 22, 2005, the Blu-ray Disc Association and DVD Forum announced that the negotiations to unify their standards had failed.[23] Rumors surfaced that talks had stalled; publicly, the same reasons of physical format incompatibility were cited.[21][24] By the end of September that year, Microsoft and Intel jointly announced their support for HD DVD.[25]

Hewlett-Packard (HP) attempted to broker a compromise between the Blu-ray Disc Association and Microsoft by demanding that Blu-ray Disc use Microsoft's HDi instead of BD-J and threatening to support HD DVD instead.[26] The Blu-ray Disc Association did not agree to HP's demands.[27]

Launch[edit]

In November 2006, Microsoft released an HD DVD playerfor their Xbox 360game console for $199. It came packaged with King Kongand could only play movies.

On March 31, 2006, Toshiba released their first consumer-based HD DVD player in Japan at ¥110,000 (US$934).[28] HD DVD was released in the United States on April 18, 2006,[29] with players priced at $499 and $799.

The first HD DVD titles were released on April 18, 2006. They were The Last Samurai, Million Dollar Baby, and The Phantom of the Opera by Warner Home Video and Serenity by Universal Studios.[30] The first independent HD film released on HD DVD was One Six Right.[31][32]

Sales developments[edit]

Although HD DVD and Blu-ray used near-identical translucent keep casesfor most pre-recorded releases, they were normally coloured red for the former and blue for the latter.

In December 2006 Toshiba reported that roughly 120,000 Toshiba branded HD DVD players had been sold in the United States, along with 150,000 HD DVD add-on units for the Xbox 360.[33]

On April 17, 2007, one year after the first HD DVD titles were released,[29] the HD DVD group reported that they had sold 100,000 dedicated HD DVD units in the United States.[34]

In the middle of 2007, the first HD DVD Recorders were released in Japan.[35]

In November 2007, the Toshiba HD-A2 was the first high definition player to be sold at a sale price of less than US$100; this was done through several major retailers to make room for the new HD-A3 models. These closeout sales lasted less than a day each due to both limited quantities and high demand at that price point. In the same month, the HD DVD promotion group announced that 750,000 HD DVD players had been sold, which included stand-alone players and the Xbox 360 add-on.[36]

In January 2008 Toshiba announced that close to one million dedicated HD DVD players had been sold.[37]

As of June 24, 2008, 475 HD DVD titles had been released in the US.[38] As of April 29, 2008, 236 HD DVD titles had been released in Japan.[39] Approximately 232 were released in the UK.[citation needed]

Decline[edit]

On January 4, 2008, citing consumer confusion and indifference as a reason for lackluster high-definition software sales, Warner Bros. publicly announced it would stop supporting HD DVD by June 2008, and the company would release HD titles only on Blu-ray Disc.[40] This was followed by news of Netflix phasing out support for the format, and Best Buy's decision to recommend Blu-ray Disc over HD DVD in its retail locations and to remove HD DVD players as part of its ongoing "HDTV advantage" promotion. Finally, retailer Wal-Mart announced that it would be supporting only Blu-ray Disc by June 2008.

On February 19, 2008, Toshiba announced plans to discontinue development, marketing and manufacturing of HD DVD players while still providing product support and after-sale service to consumers of the format (including firmware updates), effectively making the platform obsolete. The company cited "recent major changes in the market".[41][42][43][44][45] Shipments of HD DVD machines to retailers were reduced and eventually stopped by the end of March 2008.[46] Toshiba later revealed that they lost about $986 million on the format's failure.[47]

End of releases[edit]

The final HD DVD major-studio releases in the United States were Paramount's Into the Wild, Warner's P.S. I Love You and Twister, on May 27, 2008. In June, the final HD DVD, Freedom: 6, was released by Bandai Visual, which acknowledged the demise of HD DVD, but stated that it wanted to complete the release of the seven-part Freedom Project, of which six parts had been released.[48] The seventh part, due for August 2008, never saw a release. Disco Pigs was announced but postponed, with no new date announced for release.[49]Pan's Labyrinth is also notable as New Line Cinema's only film to be released on HD DVD, as the studio quickly shifted to Blu-ray.

Death Proof was released on HD DVD format as a special-release steelbook by Senator Films in Germany on December 15, 2008.[50]

On April 3, 2010, Engadget reported that Anthem Films would release the film Deadlands 2: Trapped on HD DVD in a limited run of 500 copies. This eventually happened in the form of HD DVD-Rs.[51]Deadlands: The Rising, announced on September 5, 2010, was released on HD DVD in limited numbers. As with the previously released Deadlands 2: Trapped, the film was pressed on HD DVD-R disc.[52]

Warner Blu-ray Disc replacements in the U.S.[edit]

In mid-2009, Warner offered to replace any HD DVD Warner home video release with a Blu-ray Disc equivalent for $4.95, plus $6.95 shipping to the contiguous United States or $8.95 to Alaska, Hawaii or Puerto Rico.[53] The deal required the HD DVD's original sleeve art to be returned to Warner as proof of purchase. The turnaround time for processing was approximately two weeks. Multi-disc sets were exchangeable at a discount, such as $14.95 for the five-disc Blade Runner release rather than $24.75. No exchanges were offered to customers outside the United States.

Technical specifications[edit]

The current specification books for HD DVD are listed at the DVD FLLC website.[54]

Disc structure[edit]

HD DVD-ROM, HD DVD-R and HD DVD-RW have a single-layer capacity of 15 GB, and a dual-layer capacity of 30 GB. HD DVD-RAM has a single-layer capacity of 20 GB.[55] Like the original DVD format, the data layer of an HD DVD is 0.6 mm below the surface to physically protect the data layer from damage. The numerical aperture of the optical pick-up head is 0.65, compared with 0.6 for DVD. All HD DVD players are backward compatible with DVD and CD.[56]

File systems[edit]

As with previous optical disc formats, HD DVD supports several file systems, such as ISO 9660 and Universal Disk Format (UDF). All HD DVD titles use UDF version 2.5 as the file system. In this file system, multiplexed audio and video streams are stored in EVOcontainer format.[57]

Audio[edit]

The HD DVD format supports encoding in up to 24-bit/192 kHz for two channels, or up to eight channels of up to 24-bit/96 kHz encoding.[58]

All HD DVD players are required to decode uncompressed linear PCM, Dolby Digital AC-3, Dolby Digital EX, DTS, Dolby Digital Plus E-AC-3 and Dolby TrueHD.[59] A secondary soundtrack, if present, can be stored in any of the aforementioned formats, or in one of the HD DVD optional codecs: DTS-HD High Resolution Audio and DTS-HD Master Audio. For the highest-fidelity audio experience, HD DVD offers content-producers the choice of LPCM, Dolby TrueHD and DTS-HD Master Audio.

Video[edit]

HD DVD video can be encoded using VC-1, H.264/MPEG-4 AVC, or H.262/MPEG-2 Part 2.[citation needed] A wide variety of resolutions are supported, from low-resolution CIF, all SDTV resolutions supported by DVD-Video, and HDTV formats: 720p, 1080i, and 1080p.[58] All studio-released movie titles have featured video in a 1080-line format, with companion supplements in 480i or 480p. The vast majority of releases were encoded with VC-1, and most of the remaining titles encoded with H.264/MPEG-4 AVC.

Digital rights management[edit]

Main article: Advanced Access Content System

If a publisher wishes to restrict use of its HD DVD content, it may use the Advanced Access Content System (AACS) although this is not required for normal disc playback. AACS is a standard for content distribution and digital rights management. It is developed by AACS Licensing Administrator, LLC (AACS LA), a consortium that includes Disney, Intel, Microsoft, Panasonic, Warner Bros., IBM, Toshiba and Sony. One of the advantages over CSS, the content restriction system for DVDs, is that AACS allows content providers to revoke an individual player device model if its cryptographic keys have been compromised (meaning that it will not be able to decrypt subsequently released content). There is no Region Coding in the existing HD DVD specification, which means that titles from any country can be played in players in any other country.

Since appearing in devices in 2006, several successful attacks have been made on the format. The first known attack relied on the trusted client problem. In addition, decryption keys have been extracted from a weakly protected player (WinDVD). Notably, a Processing Key was found that could be used to decrypt all HD content that had been released at the time.[60] The processing key was widely published on the Internet after it was found and the AACS LA sent multiple DMCA takedown notices with the aim of censoring it.[61] This caused trouble on some sites that rely on user-submitted content, like Digg and Wikipedia, when administrators tried to remove any mentions of the key.[62][63]

Further information: AACS encryption key controversy

AACS has also been circumvented by SlySoft with their program AnyDVD HD, which allows users to watch HD DVD movies on non-HDCP-compliant PC hardware. SlySoft has stated that AnyDVD HD uses several different mechanisms to disable the encryption, and is not dependent on the use of a single compromised encryption key.[64] Other AACS circumvention programs have become available, like DVDFab HD Decrypter.[65]

Interactive content[edit]

HD DVDs use Advanced Content to allow interactive content to be authored for discs. Microsoft's implementation of Advanced Content is the HDi Interactive Format, and "HDi" is frequently used to refer to the Advanced Content system. Advanced Content is based on web technologies such as HTML, XML, CSS, SMIL, and ECMAScript (JavaScript), so authoring in Advanced Content should be a fairly easy transition for web developers. No existing DVD authoring experience is required. In comparison, Blu-ray Disc content is authored using either a scripting environment (BDMV) or a Java-based platform (BD-J). DVD video discs use pre-rendered MPEG segments, selectable subtitle pictures, and simple programmatic navigation which is considerably more limited.

Hardware[edit]

Compatibility[edit]

Backward compatibility is available with all HD DVD players, allowing users to have a single player to play all types of HD DVD, DVD and CD. There is also a hybrid HD DVD format which contains both DVD and HD DVD versions of the same movie on a single disc, providing a smooth transition for the studios in terms of publishing movies, and allowing consumers with only DVD players to still use the discs. DVD replication companies can continue using their current production equipment with only minor alterations when changing over to the format of HD DVD replication. Due to the structure of the single-lens optical head, both red and blue laser diodes can be used in smaller, more compact HD DVD players. However, HD DVD discs can't be played on standard DVD players.

General purpose computers[edit]

HD DVD drives can also be used with a desktop/laptop personal computer (PC) running Windows XP, Windows Vista, Mac OS X v10.5 "Leopard", and many varieties of Linux. Third-party player software for Windows and Linux have successfully played HD DVD titles using the add-on drive.[66]

Released at the end of November 2006, the Microsoft HD DVD drive for the Xbox 360 game-console gives the Xbox 360 the ability to play HD DVD movies. The drive was announced with an MSRP of US$199 and includes a USB 2.0 cable for connection to the console. The first drives also included Peter Jackson's King Kong or Christopher Nolan's Batman Begins on HD DVD. The final "regular" for the drive was US$129.99 as of February 25, 2008. On February 23, 2008 Microsoft discontinued the Xbox 360 HD DVD player. On February 26, 2008, Microsoft "officially" announced that the Xbox 360 HD DVD add on drive would reflect a heavily discounted price down to $49.99.[67]

Dual-compatibility drives[edit]

In 2007, LG and Samsung released standalone consumer players that could read both HD DVD and Blu-ray Discs.[a] The machines were sold at premium prices, but failed to sell in large quantities. In May 2008, both companies announced they would stop manufacturing dual-compatibility drives.[68]

A few computer manufacturers (such as HP and Acer) sold computers with combination HD DVD/Blu-ray Disc drives. LG marketed a Blu-ray writer that also read HD DVD discs (but could not write to them).[69][70]

HD DVD / Blu-ray Disc comparison[edit]

Comparison of various optical storage media. Parameters: track pitch (p), pit width (w) and minimum length (l), and laser spot size (⌀) and wavelength (λ).

Main article: Comparison of high definition optical disc formats

HD DVD competed primarily with Blu-ray Disc. Both formats were designed as successors to DVD, capable of higher quality video and audio playback, and of greater capacity when used to store video, audio, and computer data. Blu-ray Disc and HD DVD share most of the same methods of encoding media onto discs with each other, resulting in equivalent levels of audio and visual quality, but differ in other aspects such as interactive capabilities, internet integration, usage control and enforcement, and in which features were mandatory for players. The storage size also varies: A dual-layer HD DVD holds a maximum of 30 GB of data, while a dual-layer Blu-ray Disc carries 50 GB.

Development[edit]

Even after finalizing the HD DVD standard, engineers continued developing the technology. A 51 GB triple-layer spec was approved at the DVD Forums 40th Steering Committee Meeting (held on November 15, 2007).[71] No movies had been scheduled for this disc type, and Toshiba had declined to say whether the 51 GB disc was compatible with existing drives and players. Specification 2.0 Part 1 (Physical Specification) for triple layer HD DVD had been approved in November 2007.[72]

At the CES 2007, Ritek revealed their high definition optical disc process that extended both competing high definition formats to ten layers, increasing capacity to 150 GB for HD DVD and 250 GB for Blu-ray Disc. A major obstacle to implementing this technology in either format (150 GB HD DVD will not be developed due to HD DVD's discontinuation) is that reader-writer technology available may not be able to support the additional data layers.[73]

NEC,[74]Broadcom,[75]Horizon Semiconductors, and STMicroelectronics[75] have separately developed a single chip/laser that can read both the HD DVD and the Blu-ray Disc standard. Broadcom and STMicroelectronics will be selling their dual-format single chip/laser solution to any OEM willing to develop a product based on the chip.

Variants and media[edit]

HD DVD-R / -RW / -RAM[edit]

HD DVD-R is the writable disc variant of HD DVD, available with a single-layer capacity of 15 GB or a dual-layer capacity of 30 GB.[76] Write speeds depend on drive speed, with a data rate of 36.55 Mbit/s (4.36 MB/s) and a recording time of 56 minutes for 1× media, and 73 Mbit/s (8.71 MB/s) and a recording time of 28 minutes for 2×.

The Toshiba SD-L902A for notebooks was one of the first available HD DVD writers, although it was not meant for retail.[77][78] Burning HD DVD (including Dual Layer) with a 1× write speed, it could also burn DVDs and CDs. In a test of the SD-L902A by C't computer magazine with Verbatim discs, the written HD DVD-Rs suffered from high noise levels,[79] as a result, the written discs could not be recognized by the external HD DVD drive of the Xbox 360, though they could be read back by the SD-L902A.[80]

HD DVD-RW is the rewritable disc variant of HD DVD with equal storage capacity to an HD DVD-R. The primary advantage of HD DVD-RW over HD DVD-R is the ability to erase and rewrite to an HD DVD-RW disc, up to about 1,000 times before needing replacement, making them comparable with the CD-RW and DVD-RW standards. This is also of benefit if there are writing errors when recording data, as the disc is not ruined and can still store data by erasing the faulty data. The dual-layer variant was never released and the single-layer variant was, but it is among the rarest of optical media.

HD DVD-RAM was the proposed successor to DVD-RAM for random access on optical media using phase-change principals. It would hold 20 gigabytes per layer instead of 15 gigabytes for HD DVD-R, due to differences in recording methods used, yielding a higher density disc. This variant of HD DVD was never released.

DVD / HD DVD hybrid discs[edit]

There are two types of hybrid formats which contain standard DVD-Video format video for playback in regular DVD players, and HD DVD video for playback in high definition on HD DVD players. The Combo disc is a dual sided disc with one side DVD and the other HD DVD, each of which can have up to two layers. The Twin disc is a single sided disc that can have up to three layers, with up to two layers dedicated to either DVD or HD DVD.[81] These hybrid discs make retail marketing and shelf space management easier. Another advantage is hardware cross-compatibility. The average consumer does not have to worry about whether or not they can play a hybrid DVD: any standard home DVD player can access the DVD-encoded content and any HD DVD player can access both the DVD- and HD DVD-encoded content.

HD DVD / Blu-ray Disc hybrid discs[edit]

Warner Bros. officially announced Total Hi Def (THD or Total HD) at CES 2007. THD hybrid discs were to support both HD DVD and Blu-ray Disc, with HD DVD on one side (up to two layers) and Blu-ray Disc on the other side (up to two layers). In November 2007, Warner Bros. cancelled THD's development.[82]

3× DVD[edit]

The HD DVD format also applies to current red laser DVDs; this type of disc is called "3× DVD", as it is capable of three times the bandwidth of regular DVD-Video.

3× DVDs are physically identical to normal DVDs. Although 3× DVDs provide the same high definition content, their playback time is less. For example, an 8.5 GB DVD DL can hold about 90 minutes of 1080p video encoded with VC-1 or AVC at an average bitrate of 12 Mbit/s, which corresponds with the average length of Hollywood feature-films. If quality is compromised slightly, and good compression techniques are used, most feature films could be encoded with 3× DVD. Due to its much greater resolution, HD-Video also has significantly more redundant information than DVD which newer compression standards can encode more efficiently.

It is technically possible for consumers to create HD DVD compatible discs using low cost DVD-R or DVD+R media. At least one such guide exists.[83] The 3× DVD is comparable to Blu-ray Disc BD5 and BD9 formats.

HD REC[edit]

HD Rec is an extension of the HD DVD format for recording HD content on regular red laser DVD-Rs/DVD-RWs using H.264/MPEG-4 AVC compression.[84] It was approved by the DVD Forum on September 12, 2007[85] It is comparable to Blu-ray Disc's AVCREC.

CBHD[edit]

The China Blue High-definition Disc (CBHD), a high-definition optical disc format, was based upon the HD DVD format. Like the HD DVD, CBHD discs have a capacity of 15 GB single-layer and 30 GB dual-layer and can use existing DVD production lines.
