摘要

[Problem] The present invention aims to provide a recording medium that guarantees a playback of an audio stream by an existing apparatus in a case where a stream entry of an audio stream encoded in NAC is included in a stream number table. [Solution] A recording medium having recorded thereon one or more pieces of playlist information each of which includes a stream table including multiple stream entries. Each audio stream has been encoded in one of a mandatory format that is an encoding format decodable by a playback apparatus with any version number, and an optional format that is an encoding format decodable by a playback apparatus with a predetermined or higher version number. In a first-type stream table, a stream entry corresponding to an audio stream encoded in the optional format is immediately subsequent, in the order of the stream entries, to a stream entry corresponding to an audio stream encoded in the mandatory format, the audio stream encoded in the optional format and the audio stream encoded in the mandatory format having been encoded from a same audio source and having a same language code and a same number of channels.
