| Still Picture Coding
HEVC-Intra coding might be used as the Advanced Image Coder that JPEG requires. The capabilities of HEVC-Intra coding were discussed. Evaluation of the HEVC performance will be done jointly with JPEG. Access to the Hannover and Brussels ftp-sites will be exchanged in order to use MPEG and JPEG test material. 16 bit test material is missing at this point. N14086 Test conditions for HEVC still picture coding performance evaluation describes the envisioned evaluation. This evaluation was delayed and now, it is envisioned to take place prior to the 108th meeting. The adhoc group N14167 AHG on still image coding using HEVC will also continue to work on this topic.
Profiles
Several profiles related to 4:4:4 were discussed based on input from National Bodies and members. The contention is about 8 bit and 10 bit profiles based on the RExt currently under ballot and the impact of the profiles on potential Screen Content profiles. No consensus on profiles for 8 bit and 10 bit was reached at this meeting. However, MPEG proposes NB to consider the specification of a 16 bit 4:4:4 All Intra profile for the RExt as mentioned in N14169 Response to NB on RExt Profiles. VCEG appears to be in favour of specifying an 8bit 4:4:4 profile within RExt. MPEGs position was communicated to VCEG in N14307 Liaison statement to ITU-T SG 16 on video coding collaboration.
