摘要 |
A receiving apparatus has a first memory area accessible by a first provider providing first contents and a second memory area accessible by a second provider providing second contents. A receiving unit receives a first access right file and a second access right file. An output unit outputs the first contents or the second contents. A memory control unit stores first information associated with the first contents in the first memory area and stores second information associated with the second contents in the second memory area. A switching unit switches from outputting the first contents to outputting the second contents. A determining unit determines whether the second provider is permitted to access the first memory area. An output controller reads the first information and outputs the second contents based on the first information to the output unit when the second provider is permitted to access the first memory area. |
