1.11Liaison activity


The JCT-VC did not directly send or receive formal liaison communications at this meeting. However, the rapporteur of Q6/16 (VCEG) reported that following information had been conveyed in liaison communication received at the parent-body level:

  • ITU-R SG6 had replied to the query sent to them by VCEG about the chroma positioning forin 4:2:0 sampling for in ITU-R BT.2020. The reply confirmed that the co-sited positioning (both horizontally and vertically) was intentional.

  • The DVB had reported that its specification for the use of video and audio coding in broadcasting applications based on the MPEG-2 Transport Stream, TS 101 154, includes the support for High Definition and Ultra High Definition formats encoded using High Efficiency Video Coding (HEVC). The latest version of this specification had recently been published by ETSI as TS 101 154 v2.2.1.

  • The Association of Radio Industries and Businesses (ARIB) had reported that the ARIB standard STD-B67 “Essential parameter values for the extended image dynamic range television (EIDRTV) system for program production”, specifying a transfer characteristics function known as hybrid log gamma (HLG), for which support has been included in the draft text for HEVC, had been published and was available to the public on their website (http://www.arib.or.jp/english/html/overview/sb_ej.html).
