CE-1.5, CE-1.6, CE-2.2 and CE-2.3: Rice parameter selection for high bit depths
Authors: A. Browne Sony Steve Keating Sony Karl Sharman Sony
Abstract
This document describes CE-1.5, CE-1.6, CE-2.2 and CE-2.3 from the JVET U meeting which are modifications to the method for the selection of Rice parameters for residual coding. These modifications are intended for consideration for high bit depth coding in VVC version 2. The modifications are based on those previously described in JVET-U0057[1] and JVET-T0072[2]. CE-1.5 and CE-1.6 are modifications of regular residual coding (RRC) which differ only in the regularity of parameter updates. CE-2.2 and CE-2.3 are modifications of transform skip residual coding (TSRC). The aim of the modifications is to offer BD-rate gains for high bit depths when typically residual coefficient values become larger, whilst being backwardly compatible with the existing Rice coding techniques in VVC version 1(JVET-T2001)[3].
