    <p num="0002">&lt;p&gt;Methods are described to communicate source color volume information in a coded bitstreamusing SEI messaging. Such data include at least the minimum, maximum, and average luminance values in the source data plus optional data that may include the color volume xandy chromaticity coordinates for the input color primaries (e.g., red, green, and blue) of the source data, and the color x and y chromaticity coordinates for the color primariescorresponding to the minimum, average, and maximum luminance values in the source data. Messaging data signaling an active region in each picture may also be included.&lt;/p&gt;</p>
