Title:
PLAYER DEVICE, PLAY METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2015/005189
Kind Code:
A1
Abstract:
The present technology relates to a player device, a play method, and a recording medium, whereby it is possible to display graphics at a suitable white level upon a video with a wide dynamic range of luminance. On a recording medium which a player device of an aspect of the present technology reads are recorded coded data of extended video which is video of a second luminance range which is wider than a first luminance range, luminance characteristic information which denotes a luminance characteristic of the extended video, and graphics data of the first luminance range which is superpositioned upon the extended video. The player device converts a first pixel value of the graphics to a second pixel value in accordance with the extended video luminance characteristic which is represented by the luminance characteristic information, denoting the same luminance as the luminance which the first pixel value denotes in accordance with the luminance characteristic of the graphics, and composites the extended video which is obtained by decoding the coded data with the graphics of the second pixel value. It would be possible to apply the present technology to a player which plays content.
