Program configuration management apparatus
A program configuration management apparatus restores the configuration of programs in the receiving apparatus to an original state if programs downloaded for version-up contain bugs. The program configuration management apparatus includes a program download unit for downloading programs via communication channels, a program management unit for storing the downloaded programs as well as previous versions of the downloaded programs into an object storing unit, and a history information management unit for storing history information concerning the downloaded programs into a history information storing unit. On receiving a previous version reinstallation designation for a specific program from a broadcast center, the program management unit validates a previous version of the specific program stored in the object storing unit by referring to the history information storing unit via the history information management unit.
