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

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.

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.
