FYI, Dolby's new server will play 4K content.
Well, most (all?) servers MUST (as per DCI specifications) play 2K, 4K and 2K-48fps (3D). The thing is, are they capable of outputing that to a projector w/o downscaling it to 2K?
The answer should be: yes, that's easy and simple, as it's actually harder to downscale to 2K than it is to shoot it out straight to 4K after decompression.
The problem being, until recently, there was no need to output 4K as there were no 4K projectors. Sony being the exception but using their own, "propietary/incompatible" way to input the signal.
Do you know, Brad, how the Dolby is outputing the 4K to a (future) 4K TI projector? 4K needing 4 times the amount of signal than 2K, would need either eight HD-SDI conectors or something new (like, maybe, 4 x 3G-SDI)
