FIELD: information technology.
SUBSTANCE: medium contains clips, playlists and metadata. Each clip contains a stream of AV data and clip information for attributes. Playlists are blocks for reproducing AV data. Each playlist contains a set of play elements corresponding to intervals for playing clips. Metadata are generated for such a playlist to provide a tile scene search function in the AV data. The metadata are defined scene after scene and contain information relating to a search keyword which must be applied to the corresponding scene. Title scene search is applicable when AV data are reproduced on the main reproduction path, and is inapplicable when AV data are reproduced on a secondary reproduction path.
EFFECT: providing a scene search function for titles supporting several reproduction paths.
