The future's looking very bright for Blu-ray.
Anybody know if VC-1 (formerly VC-9) is superior to MPEG4, or are they more or less the same.
If a standard DVD is 9GB and Blu-Ray is 50gb that's a 400% increase, but when you add the advanced codec into the mix, how much of a % increase would it be then, anybody hazard a guess, I'd bet it's much higher than 400% ?
LOTR in HD, oh god I think I've soiled myself
Yes, it is good news. Now it is up to the content owners to give us the best picture quality possible, be it in MPEG4 AVC HP or VC-1. I think Microsoft made a wise decision to have made VC-1 an open standard - look where it's got them now, a codec on both competing HD formats!
What about audio formats, I hope they will consider some kind of lossless system. Mind you that will mean I have to upgrade my £2000 Pioneer VSA- AX10i
Oh, yes! Lossless is a must IMO. Blu-ray have announced 8 channel LPCM (at approx 18Mbps!), but that just seems wasteful even with 50Gb to play with, when lossless would be half that rate.
The WMA codec is able encode lossless 24/48kHz 5.1 audio at 2-3mbps.
just a quick thought, but wont pcm audio mean the decoding requirments wil be smaller? Thinking of br-dvd players here.
With PCM, are we talking about CD quality here
In the preliminary Blu-ray specs they mention 16, 20 or 24 bit and 48 or 96 kHz sampling frequency. Have a look at page 45 of this pdf.
Cheers Dutch, the more I read about Blu-Ray the more I want it right now
Hopefully the 'advanced audio codecs under investigation' will include MHR for DVD-A compatibility.
The video resolution of Blu-Ray will be 1920/1080 I'm guessing, but will that be intelaced or progressive ??
The preliminary specs mention interlaced and progressive, but I think it would be a very big disappointment not to have 1080p as standard.
Sony have just aquired MGM today giving them nearly 8000 movies in their library. Blu-Ray is going from strength to strength, imho.
