JCTVC-J0031 Unification of band and edge offsets with respect to sign for SAO [K. Andersson, P. Wennersten, R. Sjöberg (Ericsson)]

This proposal unifies band and edge offset syntax with respect to sign while having similar coding efficiency compared to HM-7.0 (0.0% average BDR for common conditions). The modification consist of removing all 4 sign syntax element for band offset and instead having implicit derivation of sign similar as for edge offset.

Presentation not uploaded.

Some concerns are expressed that the constraints on the sign of the band offset potentially could introduce artifacts.

No action.
