For example, the video data may further include hybrid information indicating whether or not the video data is video data covering the second luminance dynamic range, the hybrid information being stored in a descriptor of a multiplexing layer, and the data reproduction method may further include: obtaining the hybrid information from the video data; preparing for switching between the reproduction of the video having the first luminance dynamic range and the reproduction of the video having the second luminance dynamic range, based on the hybrid information obtained; and switching the reproduction of the video having the first luminance dynamic range and the reproduction of the video having the second luminance dynamic range at a timing of a change in a video sequence.

Accordingly, switching of reproduction schemes can be prepared in advance using the hybrid information in the multiplexing layer. This allows smooth switching of the reproduction schemes.

For example, the first OETF may be an OETF defined by a linear term of luminance of the video data in a first range of the luminance of the video data and defined by an exponential term of the luminance of the video data in a second range of the luminance of the video data which is greater than the first range.

For example, the second OETF may be an OETF defined by a linear term of luminance of the video data in a third range of the luminance of the video data, defined by an exponential term of the luminance of the video data in a fourth range of the luminance of the video data which is greater than the third range, and defined by a logarithmic term of the luminance of the video data in a fifth range of the luminance of the video data which is greater than the fourth range.
