Abstract
A method for decoding a block of a picture represented in a current HDR/WCG format is disclosed. The method comprises receiving a bitstream representative of a coded block of picture, an indication representative of a default d QP table (index_d QP_table), an indication representative of a QP offset (slice_qp_delta); determining a quantization parameter responsive to the current format based on the default d QP table and the QP offset; decoding the coded block of a picture using the determined QP. Corresponding encoding method, transmitting method, decoding device, encoding device and transmitting device are disclosed. Besides an embodiment relative to adapting generic codec parameters to any HDR/WCG format as done for d QP table is also disclosed.
