PURPOSE: To normally transmit a voice signal and a data signal by multiplexing the voice signal and the data signal of polling response in a remote TV educational system. ;CONSTITUTION: A remote station constructs a studio station and a network with a satellite channel 3 and a reception signal from a satellite terminal station device 2 is converted into various kinds of signals by a signal converting part (1) 11 so as to be inputted as the respective signals of a TV picture, voice and control which display lecture contents in a terminal part 12 arranged in classrooms. Question and request student response collection result, etc., transmitted from the terminal part 12 as polling response is multiplexed in a multiplexing part 14, inputted to the satellite terminal station device 2 and transmitted to the studio station. The voice signal 102 is encoded in the signal converting part (2) so as to be inputted to the multiplexing part 14.;COPYRIGHT: (C)1993,JPO&Japio
