Abstract: The present disclosure relates to a file generation device, a file generation method, a reproducing device, and a reproducing method capable of identifying images used for generating an omnidirectional image. An MPD file generation section sets identification information for identifying captured images used for generating an omnidirectional image generated by mapping the captured images onto a 3D model. The present disclosure is applicable to a file generation device or the like generating segment files of an omnidirectional image delivered using, for example, MPEG-DASH (Moving Picture Experts Group phase-Dynamic Adaptive Streaming over HTTP).

Abstract: There is provided an information processing device, an information processing method, a program, and a recording medium that make it possible to set a dynamic range of an image to be reproduced. A BD-J execution unit sets a dynamic range of a screen to be reproduced. A video decoder generates a main video to be reproduced in the dynamic range set by the BD-J execution unit. The present disclosure can be applied, for example, to a reproducing device or the like that reproduces an optical disk that records an AV stream of a main video in a standard dynamic range (SDR) and an AV stream of a main video in a high dynamic range (HDR).

Abstract: It is possible to accurately and securely execute conversion from an MPEG-2TS format to an MP4 format. A data converting unit that executes format conversion from an MPEG-2TS format to an MP4 format sorts out TS packets storing video data from MPEG-2TS format data, selects a TS packet having a start code (SC) at the top of a payload on the basis of header information of the sorted out TS packets, and extracts payload configuration data other than the start code (SC) and sets the payload configuration data as configuration data of MP4 format data. The data converting unit determines, on the basis of, for example, a value of a transport priority set in a header of the TS packet, whether or not the TS packet is a TS packet in which a start code (SC) is set in a top region of a payload.
