Title:
REPRODUCTION DEVICE, REPRODUCTION METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2014/203747
Kind Code:
A1
Abstract:
The present technology relates to a reproduction device that enables 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 expanded video which is a video with a second brightness range wider than a first brightness range, brightness characteristics information indicating brightness characteristics of the expanded video, and brightness conversion definition information used when performing brightness conversion from the expanded video to a standard video which is a video of the first brightness range. When the information acquired from a display device as a video output destination includes information representing expanded video display performance, the reproduction device outputs expanded video data while adding frame information including the brightness characteristics information to the data of each frame. When the information representing the expanded video display performance is not included, the reproduction device outputs standard video data. The present technology may be applied in players that reproduce content.
