blu-ray has transfer bitrate bandwidth of up to 54Mbps (someone correct me if i'm wrong). for video, the maximum allocated transfer bitrate bandwidth for video is up to 40 Mbps, but according to my authoring studio (which i'm working with on a blu-ray disc project), around 30Mbps would be sufficient enough to render good picture quality. it seems that a huge bulk of that remaining bandwidth would be needed to be allocated towards audio, since we are gonna encode 8-ch audio at uncompressed linear pcm, source from 96khz/24bit masters. they can still let me include 5.1 dolby digital and dts. but to include anything else extra like a separate 2-ch lpcm is out of the question, unless i don't mind to let the video quality suffers a little bit (no can do!). in one of the chapters, where picture quality is upmost importance, my creative team is reverting to 6-ch lpcm just to up the bandwidth for the video.but i'm destined never to enjoy surround at home. i just can't afford to have cables snaking around with my old folks at home. anyway, see u around 2 weeks time in sf. maybe if convenient, u might like to visit me while i'm in the authoring studio.
