The receiver compares a machine type code indicating the version of the receiver hardware and version information showing the version of software corresponding to the machine type code with the machine type codes and version information of the program information, examines whether the version of software is updated or not, and, when the version is not updated, stores program codes to update the version. Thereby, it is possible to provide a remote maintenance method and a remote maintenance apparatus able to update the version of software, securing the matching of software and hardware, in a network of wired or wireless broadcasting. <IMAGE></p> |
