Article: Disney says Blu-ray has better PQ !!!

[MrVorhees]

But is Blu-ray winning the battle?

"We believe so and have put our support with Blu-ray at this time and that's because largely it has the better specifications. It can deliver a better picture because of the bit rate, beyond the fact that the disc has more capacity. So there's two different discs - Blu-ray and HD-DVD. Blu-ray, the dual layer, holds 50 gigabytes of data. The dual layer HD-DVD holds 30. So when you want the best picture, would you rather have 50 gigabytes of information or 30?

"So we found this meant Blu-ray had the room for the best picture and sound. The other thing it has is what we call a peak bit rate. What this is is how much data can you send over a pipe in a given second. Blu-ray can send 40Gb of information per second. HD-DVD can only do 29. So when you have an action scene and you have all this information on the screen - you've got fire, you've got people running about - you need to use so much bit rate. You have all this stuff happening and you suddenly need all this information to be sent through. Blu-ray has less limitations, so that's another benefit. It has space and it has space in the pipes.

....So we think over time Blu-ray will emerge as the single format. And we think that's best for consumers. Consumers have said that, too.

For those who dont know:

Gb = Gigabit
GB = Gigabyte

EXACTLY!!!!

I've noticed and mentioned it so many times,
i can clearly see the difference between a low bitrate video or a high bitrate video, hd dvd has sooooo many soft scenes in many of their releases,u can tell STRAIGHT by viewing without checking the mpbs.
am i the only one who has noticed that?

(view from an neutral perspective)

It would be very cool of Blu-ray could do 40Gb a second. Alas, no drive on the planet can attain that.

Blu-ray movie players can do:

54Mbps transfer
48Mbps mux bandwidth (all video + audio + subtitles)
40Mbps video

HD DVD is:

~36Mbps transfer
~30Mbps mux bandwidth
~29Mbps video

You missunterstand m8, Gb they talk about 40mbps video.

1 megabit = 0.0009765625 gigabit

So 40 Mbps = 0.039 Gbps or 0.004875 GBps

Yep. 1 gigabyte is equivalent to 8 gigabits.

Great read so thank you for sharing that bit of info. I mean most of us have already known the limitations of Hd-Dvd, but it's good to that Disney realized that Blu is the way to go.

Can't beat pro's

@E-Dogg, yes we know, but i still dont understand how HD DUD cant admit and unterstand blu-ray is far superior to HD DVD.
It just dont get in my head.

Disney has certainly proven that they know exactly what they're doing.

Poor HD DVD fanboys, brainwashed by all the promises made on AVS from team Microsoft, now realizing that the format is not going to be all that, is not going to win over all the studios, is not going to survive, is not going to breathe for much longer, etc., etc.

[aristotles]

It should have been obvious to all of you that the executive made a mistake and said Gbps when he actually meant Mbps when talking about peak throughput data rates.

Also remember that HD DVDs max 29 Mb/s video rate would happen with one DD 5.1 track and maybe one subtitle? or so. Use a DTHD, DTS-HD, or LPCM track, or several, and your video bitrate takes a nose dive (as 30 Mb/s mux - 4.6 Mb/s LPCM = ~25 Mb/s, and so forth, etc)
