Abstract:
Subtitle display during variable speed reproduction processing is made to be able to be satisfactorily performed.A video stream is generated configured by a video packet having encoded image data in a payload. A subtitle stream is generated configured by a subtitle packet that has subtitle information in a payload and in which subtitle display priority information according to the subtitle information is inserted. A multiplexed stream including the video stream and the subtitle stream is generated and transmitted. In a case where an overlap period occurs in display periods of a plurality of subtitles in a variable speed reproduction mode (in a case of N times speed (N>1)), selection of which subtitle to be displayed is facilitated by referring to the priority information, and satisfactory subtitle display reflecting an intention of the production side becomes possible.
