In-Depth Information
(1)
Video coding performance
To realize 50% reduction of coding bits with subjective quality equivalent
to AVC/H.264 High Profile.
(2)
Correspondence to a high quality video
(2.1) Resolution
From VGA to 4K (also 8K)
(2.2) Chroma format
From 4:2:0/4:2:2 to 4:4:4
(2.3) Bit length
8 - 14 bit per pixel
(2.4) Frame rate
24 - 60 fps or more
(2.5) Complexity
(i) To be possible of implementation at its standardization period.
(ii) To be possible to control the trade off between complexity and
coding performance.
(iii) To be possible of parallel processing.
MPEG HVC and VCEG EPVC are going to publish a joint Call for Proposals
on the next video coding standard in January 2010, and the target bitrates for UHD
and HDTV are currently defined as shown in Table 6.

6.3 Challenge toward UHD Video Coding
6.3.1 Trial to improve AVC/H.264
Within VCEG, experiments have shown the improvement in video coding per-
formance of AVC/H.264 using KTA and continual improvements of the reference
