Abstract
A method is disclosed that comprises: obtaining (S10) a video from a stream; obtaining (S12) information representative of one version of color mapping information; determining (S14) a color mapping information responsive to said information representative of one version; and color mapping (S16) the decoded video with said determined color mapping information.

21. A method comprising:
-
decoding a video from a stream; decoding information for identifying one version of color mapping information among at least a first version and a second version, wherein said first version and said second version map colors from a same input color gamut to a same output color gamut and wherein said first version favors the preservation of a first set of colors of said input color gamut during said mapping and said second version favors the preservation of a second set of colors of said input color gamut during said mapping, said second set of colors being different from said first set of colors; determining color mapping information responsive to said information for identifying one version; and color mapping the decoded video with said determined color mapping information. - View Dependent Claims (22, 23, 24, 25, 26)

27. A device comprising a communication interface configured to access at least one stream and at least one processor configured to:
-
decode a video from the at least one stream; decode information for identifying one version of color mapping information among at least a first version and a second version, wherein said first version and said second version map colors from a same input color gamut to a same output color gamut and wherein said first version favors the preservation of a first set of colors of said input color gamut during said mapping and said second version favors the preservation of a second set of colors of said input color gamut during said mapping, said second set of colors being different from said first set of colors; determine color mapping information responsive to said information for identifying one version; and color map the decoded video with said determined color mapping information. - View Dependent Claims (28, 29, 30, 31, 32)

33. A method comprising:
-
encoding a video in a stream; obtaining information for identifying one version of color mapping information among at least a first version and a second version, wherein said first version and said second version map colors from a same input color gamut to a same output color gamut and wherein said first version favors the preservation of a first set of colors of said input color gamut during said mapping and said second version favors the preservation of a second set of colors of said input color gamut during said mapping, said second set of colors being different from said first set of colors; and encoding said information representative of one version. - View Dependent Claims (34)

35. A device comprising a communication interface configured to access at least one video and at least one processor configured to:
-
encode said at least one video in a stream; obtain information for identifying one version of color mapping information among at least a first version and a second version, wherein said first version and said second version map colors from a same input color gamut to a same output color gamut and wherein said first version favors the preservation of a first set of colors of said input color gamut during said mapping and said second version favors the preservation of a second set of colors of said input color gamut during said mapping, said second set of colors being different from said first set of colors; and encode said information representative of one version. - View Dependent Claims (36)
