Abstract

The present technology relates to a reproduction device, a reproduction method, and a recording medium that enable content having a wide dynamic range of brightness to be displayed with an appropriate 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 brightness conversion definition information used when performing a brightness conversion of the extended video to a standard video that is a video having the first brightness range. The reproduction device decodes the coded data and converts the extended video obtained by decoding the coded data to the standard video on the basis of the brightness conversion definition information.

Claims20

Dependent claims

A device, including:

reception circuitry configured to receive:
coded data of a standard video that is obtained by performing a brightness conversion of an extended video that is a video having a second brightness range that is wider than a first brightness range, the standard video being a video having the first brightness range,
brightness characteristic information that represents a brightness characteristic of the extended video for brightness adjustment of the extended video, and
brightness conversion definition information used when performing a brightness conversion of the standard video to the extended video;
control circuitry configured to control:
decoding the coded data;
converting the standard video obtained by decoding the coded data to the extended video on a basis of the brightness conversion definition information;
and
adjusting brightness of the extended video according to the brightness characteristic information when the brightness characteristic information is transmitted as auxiliary information together with each frame of the standard video and the brightness characteristic information is distinct from the brightness conversion definition information;
and
a display configured to display the adjusted extended video.
