Abstract

A system controller reads out program information from a memory to compose a program table, causes the program table to be displayed on a screen of a CRT using an OSD circuit, issues a conversion command to a scanning line conversion circuit, and displays reduced video of the selected program on a screen of the CRT. Further, the system controller judges whether or not the selected program has not been contracted yet, for example, on the basis of information provided from a CA module, reads out from a nonvolatile memory message data representing “You cannot view” if the selected program has not been contracted yet, and causes the message to be displayed on a reduced video display area using the OSD circuit.
