Bill fra the bits, har en rigtig god gennemgang af de problmer BEGGE formater har med lyden og de BS som dvs. folk siger om enten HD DVD eller BD. Det lyder næsten som om at MS gør os en tjeneste Shocked
On the topic of high-definition today, there's no real news to report, other than that Netflix CEO Reed Hastings has urged the HD-DVD and Blu-ray Disc camps to end the format war for fear that it could hurt the adoption of high-definition movies on disc (click here to read more at Video Business). He's right, certainly, but no one in the industry with the power to do anything about it is going to listen at this point.
Actually, there is one more thing... Microsoft's European Manager for Xbox, Chris Lewis, has told Spiegel Online that his company will announce more details about the Xbox 360's forthcoming HD-DVD peripheral drive at the upcoming E3 electronic gaming conference. Rumors place the price at around $100, but there's little real information as yet. Lewis is full of marketing spin and bluster, however, saying (among other things): "Blu-ray right now reminds us of another technology from Sony: Betamax. A bit like VHS -- we think that HD DVD is the format that consumers, film studios and publishers will embrace. As you're mentioning the cost of Blu-ray -- we think it's about giving consumers choice, we think it's about not necessarily asking them to pay over the odds for a technology that, at the moment, is unproven."
I've got news for you Chris... HD-DVD hasn't really proven itself very well either. We've got a few thousand players out in the market at most, at least some of which are experiencing frustrating technical glitches, and just SIX movies. That's not much of a track record there yet. So people would be fairly stupid to count Blu-ray Disc out at this point. Or HD-DVD for that matter. It's just too early to tell.
Man, I'll tell you... I just hate listening to these corporate suits spewing their sales bullshit to a sometimes unsuspecting public like it's the gospel truth. And I'll tell you, if we do NOTHING else here at The Bits than help to hose some of that away each day, to leave you with a more accurate, honest and realistic picture of what's actually going on in the industry, then that's a damn good day's work as far as we're concerned.
Speaking of honesty and HD-DVD, I suppose I should admit that I had my first genuinely thrilling experience with the format last night. Universal's Apollo 13 HD-DVD showed up on my doorstep yesterday, and I'll tell you... the film looks and sounds better than I've EVER seen it before. Universal is really doing a beautiful job with their high-definition transfers and mastering. I suspect Apollo 13 also benefits from the work that was done a few years ago to create an IMAX version - the digital clean-up, etc (no worries though, the film is full length and 2.35:1 widescreen, as it should be). Anyway, I was VERY impressed with this disc... despite the fact that our Toshiba HD-A1 locked up not once but twice over the course of the evening. The first time, the glitch only lasted a moment, and I was able to get it to continue playing normally. The second time, when I was showing my wife how good the film looked naturally, it locked up completely and I had to unplug and reboot the player to get it going again. Go figure.
Rest assured, we'll have reviews of Apollo 13, Doom and Million Dollar Baby up in the next day or two.
Now then... changing gears just a little bit, since a lot of you have asked questions about it, I wanted to talk a little bit today about the new high-resolution audio formats available on HD-DVD, how the Toshiba HD-A1 processes them and how current surround sound receivers recognize them. And I'm going to try to boil it down into plain language (as much as is possible, anyway) for the vast majority of folks who don't have engineering degrees.
Dolby DigitalDTSLinear PCMDolby Digital-PlusDolby TrueHDDTS-HD
First up is Dolby Digital-Plus 5.1. In general, it should sound better than current DTS and actually something close to the quality of DVD-Audio and SACD (once we've got the hardware to fully take advantage of it). Currently, to enjoy the full resolution equivalent of Plus 5.1, you can either connect the player to your receiver via the analog 5.1 outputs or via an HDMI connection (although few receivers come equipped with HDMI audio capability as yet), in which case your player will decode the Plus 5.1 bitstream and convert it to LPCM 5.1 to be read by your receiver as such. The other choice you have, is you can connect your player to the receiver via the digital Toslink (optical) or coax outputs that most of us have been using for years now. Unfortunately, in this case, the HD-A1 decodes the Plus 5.1 bitstream and re-encodes it as DTS 5.1, which is then passed to your receiver (the receiver recognizes the bitstream as DTS accordingly). You're still getting a great audio experience, but it's not full Plus resolution, because DTS has a lower bitrate. It's sort of a half-assed solution that the Toshiba engineers came up with, but that's what they came up with.
Next up is Dolby TrueHD 5.1. This should sound not only significantly better than Plus 5.1, but even better than DVD-Audio and SACD - potentially as much as three times better, in fact (but again, only once we've got the hardware to fully take advantage of it). Currently, it's impossible to enjoy TrueHD on the HD-A1, because the HD-A1 only supports 2-channel decoding of TrueHD. The best you're going to get out of the HD-A1, via any connection, is stereo audio converted to either LPCM (via HDMI or analog outputs) or DTS (via the Toslink and coax digital outputs), neither of which is going to be full TrueHD resolution.
Finally, there's DTS-HD (which should roughly equate to the quality of Dolby TrueHD, although there's no software available yet and few official specs yet either). This will again be converted to either LPCM or DTS by the HD-A1, depending on which output you use with your receiver, and again this will not be full resolution either.
So the basic problem with all of these audio formats, is that there's currently no hardware available - either HD-DVD players or surround sound receivers - that supports them all fully yet. This will change starting later this year, when players and receivers fully compatible with Plus, TrueHD and DTS-HD are released, equipped with specific HDMI 1.3 connections. Current HDMI connections don't actually allow for the full-bandwidth capabilities of True HD and DTS-HD (and Toslink and either digital or analog coax connections don't have the bandwidth to allow them period). So to experience full-resolution, multi-channel audio via Dolby TrueHD or DTS-HD, you'll eventually NEED to upgrade to new hardware equipped with HDMI 1.3 - both your player AND your receiver. Is it any wonder why we've told most of you to just wait on HD-DVD and Blu-ray Disc? Even if you do buy an HD-DVD player now, you'll STILL have to buy another player later on if you want the full audio capability!
Sony, recognizing all of these audio incompatibilities and the potential for confusion, is not even including Dolby Digital-Plus, Dolby TrueHD or DTS-HD on their early Blu-ray Disc software. Instead, they're simply encoding the audio on their initial Blu-ray titles in high-resolution LPCM 5.1, until such a time as the hardware catches up. FYI, PCM audio is the same basic format that's been used for existing music CDs for many years, except that it can also be encoded in high-resolution bitrates and can support multi-channel audio in addition to just the common 2.0 stereo found on CDs. Current multi-channel receiver should all be able to accept an LPCM 5.1 signal and drive your speakers with it, just as they currently can with stereo CD audio.
Frustrated yet? Yeah... trust me, you're not alone. In any case, I hope we've been able to at least shed some light - and in a reasonably understandable way - on the situation at hand with regard to these new audio formats. You can read more about all of them, and their compatibility issues, in a great new editorial by our very own DocDVD, Josh Lehman, over at his own website (one of our Bits partner sites). It's entitled, The Sound and the Furious: The Next Generation.
Anyway, with regard to our HD-DVD (and future Blu-ray Disc) reviews, we're evaluating the current audio experience allowed on these discs as best we can, until we can really fully test and appreciate the quality of Dolby Digital-Plus, Dolby TrueHD or DTS-HD with 100% compatible hardware in the future.
So okay... there you have it. That's enough tech-speak for today, I'd say. If I've got any errors in there (there shouldn't be, but this stuff is complicated and boiling it down into real-speak isn't easy, believe me), I'll fix 'em soon and let you know about it. 'Nuff said.
Stay tuned...
Hele dette opsumere meget godt at BEGGE formater slet ikke er klar endnu....
Det sammen med at jeg ikke har en PJ ( eller råd lol! ) gør at der nok går en del år inden jeg får HD.
Så vil jeg stadig glæde til titler på SD DVD som Seven Samurai CC rerelease og Blade Runner SE ( Endeligt! ) Sammen med Superman 2 DC.
