Abstract
Installation of an application program which is not compatible with a version of an OS is prevented. On a transmission side, information bits of one code word are assumed to represent the entirety of both an application program to be distributed to a receiving side and system software, including an OS of a version with which the application program is compatible, and an ECC for the information bits is computed and is attached to the application program. On the receiving side, compatibility between the application program and the system software which has already been installed is determined on the basis of the ECC attached to the distributed application program, and the distributed application program is installed on the basis of the determination result.
