PROBLEM TO BE SOLVED: To reserve a transmission line from a studio to a transmission station by means of a digital transmission line in the analog digital simultaneous broadcasting system. ;SOLUTION: An A/D converter 11 in a studio 10 converts an analog information signal into a digital signal, and a time division data transmitter 12 transmits the digitized analog information signal and a digital information signal meant to be sent originally to a transmission line 30 in time division. A data demultiplexer 21 in the transmission station 20 demultiplexes the received digital transmission signal into a digitized analog information signal and the digital information signal meant to be sent originally, a D/A converter 22 converts the digitized analog information signal into an analog signal and an analog transmitter 23 transmits the analog signal. Furthermore, the transmitter 23 transmits the digital information signal to substantially be sent after prescribed modulation is applied to the signal.;COPYRIGHT: (C)2000,JPO
