According to this press release (also reported by Impress AV Watch), JVC has developed a prototype hybrid DVD/Blu-ray disc that integrates a one BD layer (~25GB) and two DVD layers (total of 8.5GB) on a single side. This of course means that most DVD movies will be able to be fit on the one disc and that an HD quality movie can be played as well (providing you have the player obviously). It also means that the HD movie can have reasonably high video and sound quality due to the extra capacity that a BD layer provides over a HD-DVD layer for example

More Babelfish talk:

Victor Co. of Japan, Ltd. (JVC) is the first in the world which realizes three-layer structure of BD (blue ray disk) single layer and two layers of DVDs, and can record both HD image and SD (standard) image on the disk of one sheet with an original highly efficient reflective film. * の BD-DVD combination ROM disk technology (sum total capacity of 33.5GB) was developed. (As of *: December 24, 2004)

It is the disk of the three layer structure of one side reading where this disk prepared BD single layer (it is the signal layer which stored HD image, and is the capacity of 25GB) in the surface portion, and prepared two layers (it is the capacity of 8.5GB in the signal layer which stored SD image) of DVDs in the inside. nud Fig. 1 . About the time of BD reproduction, BD layer of a surface portion is reproduced by the blue laser of BD apparatus, and an internal DVD layer is reproduced by the red laser of DVD apparatus at the time of DVD reproduction. nud Fig. 2 . While our company made full use of the disk process technology cultivated for years until now, the original highly efficient reflective film with the character "the red laser for DVD penetrates although the blue laser for BD is reflected" was developed, and three layer structure of one side reading was realized.

In addition, since the two-layer structure (capacity of 8.5GB) which is in use is adopted as the DVD layer of this disk, on the occasion of utilization, as [ of data そ of DVD software on sale ] is utilizable.
When the software which recorded the image of both BD and DVD on the disk of one sheet is put in practical use by development of this disk, ""With the small television and PC (the going-out place mobile PC) of a single room, SD image of DVD is enjoyed for HD image of BD high definition in living with" a big-screen TV. SD image is enjoyed by DVD apparatus at the beginning of soft purchase. After BD apparatus purchase becomes possible [ how to enjoy oneself of enjoying HD image of BD" ]. When the mass feature is harnessed, in addition to an image, contents, such as advertisement, music, and a game, can also be recorded, and the possibility of the disk of one sheet spreads greatly.
Moreover, since it is collected into one sheet, it is considered that BD and DVD can contribute also to saving resources and energy saving.

Our company will make the standard proposal of this disk technology to a blue lei disk association (BDA) towards utilization from now on. Furthermore, one more step of large scale-ization is also tackled and development of sum total capacity the disk of 58.5GB (BD2 layer 50 GB+DVD2 layer 8.5GB) is also aimed at.

*********
<The main features of a BD-DVD combination ROM disk>

1 The signal of both BD and DVD is recorded on the first in the world and the disk of one sheet.
- One side reading and a combination disk with [ BD layer / portion / surface ] / to the inside / the DVD layer by sticking BD layer (signal layer which stored HD image), and a DVD layer (a signal layer, two layers which stored SD image) with advanced positioning adhesion technology were realized for the first time in the world.
- Blue laser light is reflected, and red laser light develops the original highly efficient reflective film to penetrate, and applies it to BD layer. This became possible to reproduce a DVD layer by red laser through BD layer.
- The two-layer structure (a maximum of 8.5GB) which is in use is adopted as a DVD layer. Together with the storage capacity of a maximum of 25GB of BD layer, no less than a total of 33.5GB of large scale was realized.
2 The three-layer structure disk by double-sided fabrication
The manufacturing technique based on mass-production experience of a DVD disk is united with the detailed processing nanotechnology cultivated by BD disk development. By carrying out double-sided fabrication of one side of BD layer and a DVD layer, the prospect was attached to productivity almost equivalent to BD disk only for reproduction.

With this new development I can't see any reason why the HD-DVD format should survive.

I don't see the point of a hybrid Blu-Ray/DVD format. The whole point of Blu-Ray is to ell you the same movies again in a different format. If new releases were to use this format, they would cannibalize DVD sales and probably be more expensive to produce. From a consumer POV, you get a good deal only if this is less expensive than buying a DVD and BRD separately.

I agree. But I guess they think $0.1 more / disc or whatever the difference might be between HD-DVD and Blu-ray is too much.

It allows retailers potentially to avoid having to stock two versions of the same movie. Of course, that doesn't work if retailers and studios are planning oin charging a premium for HD movies.

"I don't see the point of a hybrid Blu-Ray/DVD format."

The point is that it's a much easier changeover for the movie studios, that for the transition between formats, wont have to release a DVD and BRD version of the same movies, but rather 1 edition that's gonna sell to both the DVD customers and new BRD users.

Of course such a hybrid disc would be doomed to only a few years of life while the marketplace phases out or greatly reduces DVD's importance until the H formats can have a solid foothold.

 

[Shin Johnpv]

so if they could do this with a BRDVD why couldnt they make a Hybrid HDDVD too

They've already done it.

It has been done, but the point is all the advantages that HD-DVD had are now gone except for the minor temporary price difference, while blu-ray still has several advantages of its own.

Well, it has the backing of the DVD forum as well as heavy endorsement by Toshiba, NEC, Warner Bros among others. Next gen DVD still seems rather divided for support. :/

Check this out:

Victor JP(JVC) has developed a 3 layer disk, capable of storing 33.5GB of content. The disc made up of 3 layers combines two technologies, one blu-ray layer (25GB) and DVD x 2 layer(8.5GB). Which makes it possible to use the disc in a blu-ray supported device or in a dvd supported device. It is possible to get a 58.5 GB disk if a 50GB 2 layer blu-ray disc is used. Scheduled for a 2006 release.

Intresting stuffs..

I also have a comment

Basically, Blu-ray have support from:

The worlds 2 largest Computer Manufacturers (Dell and HP)
The 2 biggest Korean CE manufacturers (Sammy and LG)
The 2 biggest Euro CE manufacturers (Philips and Thopson)
The biggest Japanese CE manufacturers not called Toshiba
The studio with the largest pre 1950 movie archive(MGM)
The studio that has TEH KIDDIE market wrapped up (Disney)
One of the biggest japanese film distribution companies (Bandai)

IMO, this is a Tall, Tall mountain for HD-DVD to climb and they, HD-DVD, in my opinion, become more and more surperfluous with every passing day...

Again, this is not even taking into account the big impact a BRD-ROM powerered PS3 will certainly have....and while HD-DVD in XENON will be a big, big help for that group, I don't see HD-DVD winning this war...
