That's correct. The decoder for the codec is in the BD player. Today's 1080p BD players are required by the BD standard to include decoders for three different codecs (Mpeg 2, VC1 and h.264) while the 4K extension for BD will likely require the decoding of HEVC. What goes across the HDMI to the TV (be it HDTV or UHDTV) has already been decoded by the BD player. The HDMI 2.0 std. will need, however, to define the signal format for 4K 3D, probably along the lines of the frame packing technique used for 1080p 3D with today's 3D BD players. The HEVC standard, defined by h.265, as it now stands is only a first step and only defines a very basic 4K at 24Hz for 2D video. Amendment 1 to h.265 which is expected to be approved in late 2013 or very early 2014 and is supposed to include 4K at up to 60Hz and also 4K 3D. It has been reported by an insider that the draft for the additional 4K capabilities is essentially complete and has been agreed by the technical group members responsible for drafting amendment 1 to h.265, so having that completed in time to be referenced by a Blu-ray 4K spec. seems feasible.
As for progress on the BD 4K standard, in an interview with CNET about 3 months ago, an exec. with the Blu-Ray Disc Association said (in part):
“As part of its ongoing responsibility to maintain Blu-ray Disc as the premium platform for watching movies and other content at home, the BDA established a task force last year to study a range of possible format extensions, including those that potentially enable 4K content playback on Blu-ray.
Through the first quarter of this year, the task force solicited and received numerous proposals, and is now evaluating the various technologies.
The task force, which is comprised of representatives from BDA member studios, consumer electronics manufacturers and media technology companies, looks forward to sharing with and receiving input from content creators, and is expected to make specification and technology recommendations to the Blu-ray Disc Association board of directors later this year.
That appears to be saying the spec. will be finished by the end of this year, which should mean 4K UHD BD players and software by late next year.
