发明名称 PLAYER DEVICE, PLAY METHOD, AND RECORDING MEDIUM
摘要 The present technology relates to a reproduction device, a reproduction method, and a recording medium that enable graphics with an appropriate brightness to be displayed on a video having a wide dynamic range of brightness. A recording medium, on which the reproduction device of one aspect of the present technology performs reproduction, records coded data of an extended video that is a video having a second brightness range that is wider than a first brightness range, brightness characteristic information that represents a brightness characteristic of the extended video, and graphics data that is superimposed on the extended video and that has the first brightness range. The reproduction device converts a first pixel value of the graphics to a second pixel value in the brightness characteristic of the extended video represented by the brightness characteristic information, the second pixel value representing brightness that is equivalent to brightness represented by the first pixel value in a brightness characteristic of the graphics, and synthesizes the extended video, the extended video being obtained by decoding the coded data, together with graphics having the second pixel value. The present technology can be applied to players that reproduce contents.
