AHG18: Rice parameter extension
Abstract
This contribution introduces an extended Rice parameter based on lossless coding flag (i.e., cu_transquant_bypass_flag). The proposed method is tested with the lossless residual coding in JVET-P0466, where transform skip residual coding methods in CE7-1.2d and CE7-1.2d-alternative are used for intra and IBC modes of lossless coding. Specifically, the proposed method extends maximum Rice parameter without additional look-up table or signaling.

This contribution introduces an extended Rice parameter based on lossless coding flag (i.e., cu_transquant_bypass_flag). The proposed method is tested with the lossless residual coding in JVET-P0466, where transform skip residual coding methods in CE7-1.2d and CE7-1.2d-alternative are used for intra and IBC modes of lossless coding. Specifically, the proposed method extends maximum Rice parameter without additional look-up table or signalling.
