SIMPLIFIED PROCESSING OF WEIGHTED PREDICTION SYNTAX AND SEMANTICS USING A BIT DEPTH VARIABLE FOR HIGH PRECISION DATA
Particular embodiments may remove a condition check in the semantics for checking a high-precision data flag. This simplifies the semantics used in the encoding and decoding process. In this case, even if the high-precision data flag is not set, the value of the weighted prediction syntax element is set by the BitDepth variable. However, even if the BitDepth is not considered high-precision data, such as 8 bits, the range for the weighted prediction syntax element is still the same as the fixed value. For example, the syntax elements luma_offset_10[i], luma_offset_11[i], delta_chroma_offset_10[i][j], and delta_chroma_offset_11[i][j] use the variable BitDepth as described above whether the flag extended_precision_processing_flag is enabled and not enabled to indicate whether the bit depth is above a threshold.
