For those of you who think the 4K stack (what is used to support 4K video/blu-ray players) is useless to you, this is what Sony is going to do next year with ATSC 2.0 and the hevc (h.265) 4K codec.

Broadcasters Perspective on ATSC 2.0
Both of the above should be viewed, lots of pictures and fairly easy to follow. This is the end game and the reason for the PS3 having Blu-ray, 1080P support and browser, it's the endgame and only realized in hindsight. Both Microsoft and Sony are preparing to Support this for 2013 so most of this should be in the PS3 and Xbox 360 by the end of the year. Blu-ray only because a blu-ray player has the ATSC 2.0 codec h.264 AVC, 1080P & 3-D support, Java (EU DVB hbbTV Apps standard) and browser for XHTML (US apps standard). In 2001, Blu-ray players were speculated as set top boxes to support ATSC 2.0; this is how long ago this was planned. This is also the reason Sony was in no hurry to port a modern browser (waiting on a standard for ATSC 2.0 to be supported)
