The method includes determining one or more first units of video content in a grouping of units and analyzing whether the one or more first units of video content within a region in the grouping of units have coefficients for the video content that are zero. The method then determines whether a quantization parameter for one or more second units of video content different from the one or more first units of video content is to be used to derive the quantization parameter for the one or more first units of video content. When the quantization parameter for the one or more second units of video content is to be used, the quantization parameter for the one or more first units of video content is derived from the quantization parameter for the one or more second units of video content.
