Abstract: Disclosed is a system for compensating a viewer for viewing of a designated channel with reduction of telephone charges. The system comprises a signal input port to which image signals from a plurality of channels are accessed; a signal output port for supplying the image signals to a picture receiving device for displaying them; a telephone network port to which an external telephone network is accessed; a telephone connection port accessed to a telephone set; a channel filtering unit connected between the signal input port and the signal output port, for outputting only the image signals from a single channel among the plurality of channels to the signal output port; and a controller for controlling the channel filtering unit so that the designated channel is output when making a phone call. With this configuration, an audience rating of the designated channel can increase and the telephone charges of the user can be reduced.
