The CICP Chunk identifies explicit characteristics of an image which is described in H.273. CICP is used in every video wrapper and in many codecs to identify the images contained...
cLLi (Content Light Level Information) identifies luminance characteristics in the content itself and provides a method for tone mapping optimization.
