Abstract

PURPOSE:To obtain the ease and confidentiality of control program mode setting for a satellite decoder by providing an operating mode discrimination device, an operating mode selection device, and a microcomputer program down-loading changeover device comprising an operation start device and a memory in matching with its operating mode switching signal to the system. CONSTITUTION:The system is provided with an FSK data demodulator 9, an operating mode selector 10, a memory 11 comprising operation start devices and programs and an input output device 12. At first, FSK down-load data from a center 13 are inputted to the FSK data demodulator 9 and any of several kinds of operation modes set in the memory 11 is selected by an operating mode control data signal 14 resulting from the discrimination of which mode is to be in use. Then the memory 11 starts the operation in matching with an operation mode switching signal 15 from the operation mode selector 10 by using each operation start device and each program. Thus, the facility and confidentiality of the control program mode setting for a satellite decoder are obtained.
