Title:
REPRODUCTION DEVICE, REPRODUCTION METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2014/203746
Kind Code:
A1
Abstract:
The present technology relates to a reproduction device for enabling the display of content having a wide brightness dynamic range with appropriate brightness, a reproduction method, and a recording medium. In a recording medium reproduced by the reproduction device according to an aspect of the present technology, there are recorded coded data of an extended video which is a video having a second brightness range wider than a first brightness range, brightness characteristics information indicating the brightness characteristics of the extended video, and brightness conversion definition information used when performing brightness conversion from the extended video to a standard video which is a video having the first brightness range. The reproduction device decodes the coded data and, on the basis of the brightness conversion definition information, converts the extended video obtained by decoding the coded data into the standard video. To a display device capable of displaying the extended video, the data of the extended video and the brightness characteristics information are output. To a display device not capable of displaying the extended video, the data of the standard video is output. The present technology can be applied to players for reproducing content.
