The Joint Collaborative Team on Video Coding (jct-vc) of itu-t wp3/16 and iso/iec jtc 1/ sc 29/ wg 11 held its tenth meeting during 11-20 July 2012 at the City Conference Centre (ccc), a k. a

JCTVC-J0051 AHG6: Crosscheck of independent luma and chroma SAO on/off control at slice level in JCTVC-J0087 [C.-M. Fu, Y.-W. Huang (MediaTek)]
JCTVC-J0132 AHG6: SAO One Unit Parameter Signalling [Y. Chiu, W. Zhang, L. Xu, Y. Han, Z. Deng, X. Cai (Intel)]

This contribution proposes a one unit SAO parameter signalling scheme to increase the flexibility of SAO syntax design. Flags are added into slice header to specify if all of LCUs in the slice are processed using the same SAO parameters.

In case of flag set to on, all merge flags will be inferred to be on.

No results were presented, though it is a proposal for better coding efficiency.

In the last meeting, a similar method was proposed for APS (I0130), but this did not show coding efficiency benefit.

The slice header would not be a suitable place for coding efficiency tools (slices are mainly for resync purposes).

No action.
