A bi-directional broadcasting system for preparing a plurality of pay video programs and a plurality of channels on the broadcasting side and designating one of the plurality of channels according to the selection of a specific pay video program by the receiving side to thereby broadcast the selected pay video program through the selected channel as occasion demands. In the bi-directional broadcasting system, a predetermined CM is broadcasted according to the allowable degree of video reception by each viewer prior to the broadcasting of the pay video program selected on the receiving side. A dip switch attached to a receiver is set according to the allowable degree of video reception by each viewer. Information about the setting of the dip switch is transmitted to the broadcasting side through a modem upon selecting the pay video program. Further, a control unit for controlling the frequency of reception of CM in the form of a picture is provided in a remote control transmitter. According to the above construction, the broadcasting side can properly correspond to the allowable degree of CM reception by the viewer. When the CM is sent to the viewer, the viewer can reliably watch it. <IMAGE> |
