Yeah I wonder how soon Ultra-Hi-Def will be in the home. It is now in the cinema anyway, as the local Odeon cinema now has a new Sony (woo :P) projector, that has a definition of about 4000 x 2000, unfortunately I have yet to see it, so can't comment on how good it is. :( |
We're gonna be waiting awhile for UHDV in home: from wiki
Eighteen minutes of uncompressed UHDV footage consumes 3.5 terabytes of data and one minute of uncompressed footage consumes 194 gigabytes (2 hours of full length movie will use roughly 25 terabytes of storage). If 1920×1080p60 high definition video has a bitrate of 60 Mbit/s using current MPEG-2 compression technologies, then four times the width and four times the height will roughly require 16 times the bitrate, which translates to 100 GB for 18 minutes of UHDV, or 6 GB per minute if MPEG-2 video compression was used. If H.264 (MPEG-4 AVC) or VC-1 video compression technologies were used then roughly half the bitrate of MPEG-2 would be required to achieve the same quality, meaning 50 GB for 18 minute of UHDV, or 3 GB per minute. (These numbers assume compressed data rates scale linearly with resolution. They do not, so actual compression numbers would be much better.)
