DVD Forum green lights three-layer 51Gb HD-DVD
The DVD Forum, the group behind the technology for DVD and HD-DVD has gone ahead and approved a proposal by HD-DVD spearhead Toshiba to produce a triple layered 51Gb HD-DVD disc. This move is a blatant show of power towards the current capacity of Blu-ray being only capable of 50Gb. Even format wars don't appear to be safe from the likes of the "mine's bigger than yours" defense.

Toshiba had announced the three-layer disc to its partners back in January, but it was only just formally submitted to the DVD Forum in April and just now approved for production.



With current HD-DVD standards, you have your 15Gb and 30Gb varieties with the single-layer and dual-layer structures currently available. Adding a third layer would essentially only amount to 45Gb, 5Gb shy of Blu-ray, so Toshiba pressed its workers to get an extra 2Gb per layer out of their new proposed structure. This is how they achieved the 51Gb storage space capability.

Toshiba says that only a Limited number of early adopters should be affected by this as the market isn't wholly saturated with HD-DVD players. There are no talks as to when these discs will actually become available or when we can expect the players to make an appearance.

    Funnily enough the truth is that 51gb (and 17gb per layer) turned out to be easier to do than 45gb (& 15gb per layer).

    It's handy that it removes one of the last bragging rights in the pi*sing competition
    (the only other remains to be seen, if the 1.5x spin speed has been maintained - it was a part of the old 45gb TL disc specs - then HD DVD will also have the highest raw bit rate too) but there are very very few films that genuinely need this size of disc.

    Disney are said to want it but besides something out of the ordinary (like some special editions - the extended LOTR movies for instance) I don't see too many coming out on it.

    The other option will be for burning (and there are rumours that the reason why HD DVD desktop PC burners have been delayed is to get the TL burning nailed as an option for home users).

    It's also worth bearing in mind that the HD DVD side sees a big future in the Total format (HD DVD and SD DVD on a single side of the same disc, not a flipper like the current 'combos').

    It expect CES will see the handful of 51gb titles revealed, the news that it will be compatible with all HD DVD players and the state of play regarding burners.

    All ways around it's more good news for HD DVD.

    Lmao your bragging about 1 dam gig........

    LMAO.

    No. I wasn't "bragging".
    (I suppose Afterdawn is "bragging" too by even mentioning this news too, huh?)

    Commenting on the news?
    Yes.

    Mentioning that 17gb turned out to be easier to do than the original 45gb TL discs?
    Yes.

    Mentioning that the 'Total' version is a coming big deal to HD DVD?
    Yes.

    Mentioning the rumoured role HD DVD burners will play in relation to this development?
    Yes

    ......and if you want to get specific about it it's actually more than just 1gb.

    Blu-ray's supposedly '50gb' dual layers don't use more than 47gb cos the failure rates go through the roof if they try that.

    So around 4gb will be the truth of it.

    But of course now that HD DVD has matched (and exceeded) Blu-ray's capacity you'll be a convert to the HD DVD 'position' that sheer size is, in itself, mostly irrelevant.

    Very funny that.

    Clearly some of you guys (wonder who created a new account just for this idiocy, huh?) just can't bear any positive HD DVD news, right?

    Here's a little more info on the TL 51gb disc.

    At the recent DVD Forum vote (but before the most recent meeting) on the V1.9 version Disney voted in support of the new discs.

    (Normally the members of the BDA abstain from voting on HD DVD matters.......

    ......this state of affairs came about when they were publicly shamed after it was revealed that some of them were abusing their position on the DVD Forum by using their votes in an act of naked anti-competitive behaviour and voting against HD DVD developments.)

    Quote:Walt Disney Home Entertainment, a major Hollywood studio and one of the strongest backers of Blu-ray disc format, voted for approval of a preliminary specification of 51GB triple-layer HD DVD media, just like all the backers of HD DVD and unlike some other backers of Blu-ray Association within the DVD Forum, who typically abstain in HD DVD-related votes.

    At the Steering Committee meeting in September Walt Disney Home Entertainment voted for triple layer twin-format HD DVD as well as triple layer HD DVD 51GB revision 1.9 preliminary media standards, according to the notes from the event available at the DVD Forum. During the meeting, twelve steering members of the DVD Forum out of twenty approved the former and eleven members approved the latter.

    In both cases Walt Disney voted for the new HD DVD standards, whereas Samsung Electronics, which supports both Blu-ray and HD DVD with its Blu-ray disc (BD) and unified Blu-ray/HD DVD players, decided to abstain in voting for the 51GB HD DVD, just like some other members of the Blu-ray Association, who always withdraw from HD DVD votes, namely Hitachi, JVC, Mitsubishi, Panasonic, Philips, Pioneer, Sharp and Sony.

    Just last week the DVD Forum approved revision 2.0 of triple-layer HD DVD 51GB media, but the detailed results of the vote were not available at press time.    http://www.xbitlabs.com/news/multimedia/...a_Approval.html

    - So the consideration must be, how long until Disney go format neutral?

    (and before the Blu-ray fanboys kick off it has to be said that this speculation has a hell of a lot more of a concrete basis than the absurd Blu-ray fanclub (and the equally laughable 'insiders) and their risible wild claims that Universal were about to go format neutral at any moment (which they kept up for much of 2007 until it became too blindingly obvious that that was never going to happen)
    or
    the equally ludicrous claims that an XBox 360 Blu-ray attachment was due at any second (which again they kept up for much of 2007 until it too became to laughable to bother trying on).
