FILE GENERATION DEVICE, FILE GENERATION METHOD, FILE REPRODUCTION DEVICE, AND FILE REPRODUCTION METHOD

摘要

The present technique relates to a file generation apparatus, a file generating method, a file reproduction apparatus, and a file 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 storing data of images of a subtitle or the like and HDR information which is to be applied to the images in an MP4 file or the like.
