1. A digital video decoding system that includes a decoder with a processor for decoding an input bit stream in a format that does not accommodate a digital video data set including a second color gamut video data, to reconstruct an output digital video data set including second color gamut video data, the digital video decoding system comprising:
(a) said decoder receives the input bit stream and decodes the input bit stream to recover a decoded standard digital video data set from the bit stream that includes a first color gamut having a first color space capable of representing a first range of colors;
(b) said decoder receives metadata from the bit stream related to an inverse function to be applied to the decoded standard digital video data set that includes said first color gamut having said first color space capable of representing said first range of colors;
(c) wherein said metadata includes data related to said inverse function;
(d) said decoder determines an inverse function based on the metadata; and
(e) said decoder applies the determined inverse function to the decoded standard digital video data that includes said first color gamut having said first color space capable of representing said first range of colors to generate an inverse transformed video data including the second color gamut video data that includes a second color gamut having a second color space capable of representing a second range of colors, where said second color space is greater than said first color space;
(f) where said bit stream is adaptable on a segment by segment basis based upon changes in said metadata item being provided on a segment by segment basis where said metadata is different on said segment by segment basis for a plurality of at least three sequential segments, wherein said generated second color gamut video data has a different color gamut for each of said at least three sequential segments based upon corresponding said changes in said metadata item being provided on said segment by segment basis.
