A configuration is realized that allows reproduction control on the basis of age at the time of reproduction by recording information regarding age permitted for reproduction corresponding to media recorded content. A clip AV stream file storing content to be reproduced acquired from input data including MPEG-2 TS format data or MMT format data and information regarding age permitted for reproduction corresponding to content acquired from the input data are placed into a playlist file, a clip information file, a usage control information file, or other file and recorded in media. A reproduction apparatus reads the information regarding age permitted for reproduction corresponding to the content to be reproduced from the playlist file or other file and compares the information regarding age permitted for reproduction with user's age information, thus allowing for content reproduction to be controlled.
