    Howdy Pardners! How long you reckon until we see affordable Blu-Ra
    players and burners for our desktops?

    Blu-Ray 33.5GB Digital Storage for HDVD


    The new Blu-ray/ DVD combo ROM disc has a one-side readout, tripl
    layer structure comprised of an outside Blu-ray disc (BD) layer an
    inner DVD dual layer. The outer BD layer is capable of storing hig
    definition video signals up to a capacity of 25GB. The inner DVD dua
    layer can store up to 8.5GB of standard definition video signals
    During Blu-ray reproduction, blue laser read the outer BD layer, whil
    red laser read the inner DVD dual layer during DVD reproduction. Th
    triple layer structure was made possible by the development of
    high-performance reflective film that reflects blue laser used fo
    Blu-ray reproduction, but is transparent to red laser used in DV
    reproduction. The proprietary technology builds upon JVC's pas
    developments in the field of disc processing technology.

    The inner DVD layer of the Blu-ray/ DVD combo ROM disc has an 8.5G
    dual layer structure, the current mainstream structure for commerciall
    available DVD software releases. The new disc is capable of storing al
    of the data currently contained in commercially available DV

  2. But does it do linefeeds after about 78 characters?

    Somehow I cant imagine companies doing a regular DVD and a HD content
    DVD at the same time for the price theyre doing with a regular DVD
    right now... especially when sometimes they cant even get the first
    one right. And I dont think that the world is going to run out and
    buy a blue-ray/HD DVD player for the prettier picture (and to make the
    MPAA feel secure with a new protection scheme) when many of us dont
    even make full use of our current DVD players yet. A DL blueray
    recorder would be damn nice for data storage though. Beats the hell
    outta what HD DVD is trying to offer anyways.

  4. Yes I agree with that, blue ray is technically superior, and on that ground
    makes a move to the new format more attractive.
    I just wonder if in that standard we can have jpg overlays, and not just bitmap
    overlays (for example for subs).
    jpeg overlays would be space efficient (that run length encoding in DVD is
    full of limitations, for example the 1440 bits / line).
    jpeg overlays would allow for nice pics, better fonts....
    I have no data on any specs for blue light disks yet, programming some stuff
    for it could prove interesting.
    Hopefully they will release specs in the public domain, that sure would help
    So, it is not only the recording density but also the control and format
    that is important.

    HD-DVD are aiming so low with their format that it's an embarrassment - I
    wouldn't be surprised to see layer changes in HD content if that format were
    adopted and there's just no excuse for ugly layer changes with today's

    I just wish companies would come up with a format that's going to last a
    little longer rather than pushing something that they know damn well will be
    massively superceded within 5 years. Not that it matters - none of today's
    attrocious Chinese electronics lasts 5 years... </rant>

    FWIW, I agree with this. I've been watching the
    whole Blu-Ray debate and scratching my head,
    wondering who'd bother with it.
