Abstract:
1. A non-transitory computer-readable medium tangibly embodied in a storage device encoded with instructions which, when executed on a processor, perform a transmission method for transmitting video data representing a color gamut beyond a first color gamut specified by a predetermined requirement, the transmission method comprising: detecting, from the video data, a section corresponding to video of a color gamut beyond the first color gamut; generating supplemental data pertaining to the video data; and embedding the supplemental data pertaining to the video data in the detected section corresponding to the video of the color gamut beyond the first color gamut, with a change to a color beyond the first color gamut, the color having substantially a same hue as that of video to be represented, the color having substantially the same hue being obtained by changing a signal to a color on a line connecting desired color coordinates to color coordinates indicative of white in a chromaticity diagram, wherein: the detected section includes a plurality of pixels of an original color; the supplemental data is embedded in the detected section by modifying the original color of each pixel such that a first dither color and a second dither color are alternately provided for each pixel; the first dither color and the second dither color produce the original color on average; and the first dither color is within the first color gamut and located in proximity to a boundary of the first color gamut.
