PURPOSE: A method for programming automatically the interactive program of a digital satellite broadcasting is provided to give a viewer's opinion with a remote controller by using the data transmitting/receiving function of a digital satellite broadcasting. CONSTITUTION: If an automatic programming list is inputted from an APS(Automatic Programming System) (200), the videotape loaded in a VCR(video cassette recorder)1 of a program file unit is reproduced to start the guide of an interactive broadcasting program(202). A main program is loaded in a VCR2, and sub-programs are loaded in a VCR3 and a VCR4(204). When a broadcasting is started, the VCR2 is operated to provide a master control unit with the first portion of the sub-programs(206). The provided image and sound signal are modulated to a satellite television signal, and transmits to a satellite. Therefore, the digital broadcasting is displayed in the satellite TV set of each subscriber. Next, it is checked whether a public opinion investigation is started(208). If the public opinion investigation is started, an automatic programming control unit generates an automatic programming control signal for operating a public opinion investigation system(210). An APS signal is inputted(224), and it is checked whether a public opinion investigation is started. If the public opinion investigation is started, an additional signal multiplexed with the image and sound signal is generated and transmitted to the satellite.
