PROBLEM TO BE SOLVED: To easily revise a program in a short time by having only to transmit general-purpose script data from a data transmitter so as to individually update script data of data receivers. SOLUTION: The data transmitter transmits the generated general-purpose script data to the data receiver, and each data receiver receives the script data. A script control program of each data receiver reads the received script data, checks the connection of tuners and audio visual devices provided in the data transmitter according to the script data, and controls the connected devices to automatically conduct reception/reproduction.
