DATA GENERATION DEVICE, DATA GENERATION METHOD, DATA REPRODUCTION DEVICE, AND DATA REPRODUCTION METHOD

摘要

The present technique relates to a data generation apparatus, a data generating method, a data reproduction apparatus, and a data reproducing method capable of enabling a user to enjoy an HDR image. HDR information designated by HDR designating information is acquired from a file storing a track of a stream including the HDR information which is configured with feature information representing features of luminance of an HDR (high dynamic range) image having a dynamic range higher than that of an STD (standard) image and conversion information representing a conversion rule of converting the one of the STD image and the HDR image into the other and a target track including the HDR designating information designating the HDR information which is to be applied to the target track of interest in the HDR information of the track. The present technique can be applied, for example, to the case of applying HDR information to a subtitle having an SMPTE-TT format using XML.
