Copyright and distribution access were discussed. It was commented that the ITE/ARIB sequences may not be especially good quality. The usage terms and cost for access to the ITE/ARIB sequences were not entirely clear.

JCTVC-J0078 AHG12: Non-4:2:0 formats syntax modifications [P. Andrivon, P. Bordes (Technicolor)]
This contribution presents syntax modifications to Draft 7 (JCTVC-I1003_d2) of HEVC in order to prepare the support of non-4:2:0 formats in HEVC profiles. It is reported that proposed Draft 7 syntax modifications are twofold: adaptation of syntax to support non-4:2:0 chroma subsampling formats and simplifications by parsing only chroma syntax elements that are necessary in the decoding process.
This contribution discusses high-level syntax only. It describes adjustments to syntax – mostly as done for AVC.
It was remarked that the separate colour plane mode has not been so popular, although it is reportedly used in some applications – e.g. military. It was remarked that now that we have other parallelism tools that may make this less necessary.
Editorially, it is desirable to go ahead and put support for 4:2:2 and 4:4:4 into the HLS in the draft – in pathways that are not actually exercised by currently-allowed syntax element values – but considering separate colour plane flag as a lower priority. This was agreed. Decision (Ed.): Editor action item.
