Patent ID: 8127352

Claim:
An information processing system which includes a compound content generation apparatus and a compound content consumption apparatus and processes a plurality of protected contents, the compound content generation apparatus comprising: at least one processor configured to execute a computer-readable program recorded on a computer-readable recording medium, the program being executed to provide: a compound content generation unit configured to generate a compound content from a plurality of protected contents, wherein a usage condition is set for each of the plurality of protected contents, and the compound content consumption apparatus comprising: at least one processor configured to execute a computer-readable program recorded on a computer-readable recording medium, the program being executed to provide: a first determination unit configured to determine whether or not one usage condition for the plurality of protected contents is stored in a storage unit; a composite usage condition generation unit configured to generate a composite usage condition by obtaining an intersection of condition values of the usage conditions set for the plurality of protected contents if the first determination unit determines that the usage condition is not stored; a second determination unit configured to determine whether the compound content is usable by using the stored usage condition if the first determination unit determines that the usage condition is stored, and determine whether the compound content is usable by using the generated composite usage condition if the first determination unit determines that the usage condition is not stored; and a compound content consumption unit configured to permit a consumption of the compound content based on a determination result by the second determination unit.
