发明名称 Reproduction Device, Reproduction Method, Reproduction Program, Recording Medium, and Data Structure
摘要 User's operations for a player can be easily restricted. A restriction mode that restricts user's operations that control the player that reproduces contents are preset. A value that represents a restriction mode for each play list is recorded as attribute information on a disc. When the player reproduces contents from the disc, the player creates a table corresponding to a restriction mode for each play list. The player references the table and filters control commands corresponding to user's operations that control the reproduction of contents using a command filter. Restriction modes includes a mode causing the player to reproduce a play list from beginning at predetermined speed for example 1x speed and a mode prohibiting the player from jumping while it is reproducing a play list. The load of the content creator side that verifies restrictions against user's operations decreases. The load of the player side that verifies operations decreases.
