SAO Modification for 12-bit
Authors: A. Browne Sony Karl Sharman Sony Steve Keating Sony
Abstract
This document proposes a change to the formula for the offset for SAO. This offset ensures SAO is applied with the same relative magnitude for bit depths greater than 10 as it is at bit depths of 8 and 10.
Meeting Notes
JVET-Q0441 SAO Modification for 12-bit [A. Browne, K. Sharman, S. Keating (Sony)]

This document proposes a change to the formula for the offset for SAO. This offset ensures SAO is applied with the same relative magnitude for bit depths greater than 10 as it is at bit depths of 8 and 10.

The adjustment is equivalent to the one introduced in HEVC RExt.

Decision: Adopt JVET-Q0441.
