Abstract

A recording center station includes functions for receiving a broadcast wave and saving or recording received data. In response to a request from each receiving station, the recording center station substitutionally records a specified broadcast program and provides a recorded content. There may be the case where the receiving station cannot record a reserved program independently due to insufficient free space remaining in a recording medium or a recording apparatus failure. In this case, the receiving station can automatically issue a recording substitution request to the recording center station for substitution of the program recording.
