I am at CES and have visited the Sony booths and the NanoTech booths (and several others) multiple times. First the Sony vw1000 upgrade and the "puck." Apparently the projector HDMI input 2, meant for the puck, is special for the puck. There is some kind of processing that occurs in the projector for the video coming from the puck. Otherwise it is an HDMI 1.4 input. I think HDMI input 1 becomes a true HDMI 2.0 input. There is lots of fuzzy data from Sony reps. I am supposed to get my upgrade in the weeks after I return from CES. Also there may be some "coupons" for the movies that were disabled on the puck after December (some Sony reps were ignorant of the expiring dates on theses movies; eek: there is a rant here about Sony Corp dysfunction that I will not start now). I will report more on this.
Also the PS4 "might" be able to do 4K streaming. Reps think it has the hardware, needing only firmware upgrades. HDMI 1.4? 2.0? 2.2? 4:4:4 color space - who knows.
As to Mark's questions regarding the NanoTech Nuvola devices: NP-1 streaming box ($299) and NP-H1 server ($699). They both have only one HDMI output. The NP-H1 server has also optical and analog audio outputs (but they were not promoting these at the booth; they were in the back supplying the video; the NP-1 is expected to be available in final version next week). If you want to split the HDMI output and pass one to an HDMI audio input on your receiver (non 4K) and one directly to your 4K projector, a possible solution is the Accell 1:2 splitter for $79. I talked to the Accell people and all their new HDMI switches, since CEDIA, are HDMI 1.4 and 4K/30 fps compatible (recognizable by the "dog ears" for rack mounting). The question is whether if you send one splitter output to your non 4K AVR and the other to your 4K projector, will the HDMI handshaking have a fit. It shouldn't, but I have seen crazier stuff from HDMI handshaking. I will be checking this when I get both NanoTech Nuvola devices and Accell splitters for review in the near future on my, hopefully, upgraded VW1000 .
I also visited the HDMI booth. They have brochures about HDMI 2.0 but good luck getting any real info.
