Abstract: A content reproduction apparatus including reproduction unit configured to reproduce content data item stored in recording medium storing first server identifier and content data item including destination identifier, reads first server identifier from recording medium, to store first server identifier in table, certifies first server corresponding to first sever identifier, receives first server policy from first server being certified, first server policy including second server identifier redirecting to second server, to store second server identifier in table, certifies second server, acquires destination identifier while reproduction unit reproduces content data item, determines whether destination identifier being acquired is equal to first identifier stored in table, and accesses to second server, when at least destination identifier is equal to first identifier and second server is certified.

Abstract: According to an aspect of the present invention, there is provided with a contents player including: a reading unit which accesses data carrier and reads out contents including multimedia data and a script from the data carrier; a playing unit which plays the multimedia data included in the contents; an interpreting unit which interprets the script included in the contents; an access unit which accesses an internal or external storing device; an acquiring unit which acquires an access ID of the contents from the read contents or the data carrier when the script includes an access instruction description which instructs access to a specific storing region in the storing device: and a determining unit which determines whether the access to the specific storing region is permitted or not, on the basis of the acquired access ID.

Abstract: According to one embodiment, to implement video objects to be played back by a method different from an existing playback sequence, playlist information which is played back first is recorded when the medium stores an advanced content. The playlist information may be configured to include object mapping information which is included in each title and is mapped on the title timeline, playback information for each title described based on the timeline, and so on. The object mapping information may describe timings on the timeline to be loaded into a playback system for each predetermined information unit such as an application or object.

Abstract: According to one embodiment, video objects to be played back by a method different from an existing playback sequence with respect to contents recorded on a read-only information storage medium are implemented. The medium is configured to store startup information including one or more pieces of playlist information to be played back first when the medium stores an advanced content, and information used to determine which one of the pieces of playlist information is to be adopted.
