for those, like me, who have seen the DCI acronym mentioned on avs, but didn't know what it referred to, here is the spec for the Digital Cinema Initiative:http://www.dcimovies.com/specification/index.tt2
You can also find an About page to learn about their reasons for working on the DCI.
Looks like JPEG2000 compression of 2K (2048x1080) and 4K (4096x1080) frames, with audio format supporting a whole mess of speakers ... do the good commercial theatres really have 5 speakers behind the screen??
If JPEG2000 is intra-frame compression only, i.e. each of the 24fps is compressed by itself in a lossless manner, and as such there is no interframe compression, that would mean way way more data than BluRay. If BR is like 10-20GB (??), what would one of these movies consume in terms of HDD at 4K?
I am interested, as the effective quality of JPEG2000 would have obviously be far better than VC1 or H.263 or whatever... BUT, for me to dive in, and I WOULD, the SIM2 can't be the projector of choice.... JVC RS20 Alan, and you can sign me up as a customer for sure.
