A system and method for a media processor separates the functions of topology creation and maintenance from the functions of processing data through a topology. The system includes a control layer including a topology generating element to generate a topology describing a set of input multimedia streams, one or more sources for the input multimedia streams, a sequence of operations to perform on the multimedia data, and a set of output multimedia streams, and a media processor to govern the passing of the multimedia data as described in the topology and govern the performance of the sequence of multimedia operations on the multimedia data to create the set of output multimedia streams. The core layer includes the input media streams, the sources for the input multimedia streams, one or more transforms to operate on the multimedia data, stream sinks, and media sinks to provide the set of output multimedia streams.

The present invention is the playback apparatus 400 for (i) mounting thereon the BD-ROM 200 in which a plurality of data groups and an application program that refers to each of the data groups are stored and (ii) playing back each of the data groups by executing the application program. The playback apparatus 400 comprises: the playback processing unit 412 operable to control the execution of the application program; the network IF unit 419 operable to obtain, from an external server including therein one or more alternative data groups, an alternative data group to replace part of the data groups; and the HDD unit 418 that stores therein correspondence information showing a correspondence between a storage location where on an internal recording medium the alternative data group is stored and a storage location where on the external recording medium the part of the data groups to be replaced. Here, at a time when the application program in execution reads a data group being referred to, the playback processing unit 412 (i) judges based on the correspondence information whether an alternative data group for replacing the data group being referred to exists on the internal recording medium, and (ii) specifies, as a data retrieve destination, a storage location of the alternative data group indicated by the correspondence information when the judgment is affirmative.

The present invention provides systems and methods for logically organizing data for storage and on a data storage medium using a multi-level format. The present invention also provides systems and for protecting data stored on data storage medium so that the data may be recovered without errors.

An information storage medium storing management information of an application executable from a plurality of information storage media, and a method and apparatus for executing the application based on the management information are provided. The method includes: if a new information storage medium is inserted into a reproducing apparatus during the execution of the application, reading information on an identifier of the new information storage medium; and determining whether to continuously execute the application based on the information and continuously executing the application according to a result obtained by the determination. The information on the identifier of the new information storage medium may be included in the application or in an application management table (AMT) of the information storage medium. A life cycle of a disc unbound application is managed so as to use an application that can be shared by different information storage media.
