PURPOSE: A one-microcomputer control system of dual type A/V equipment for a vehicle is provided to control both a monitor and a set-top with one microcomputer, thereby reducing the microcomputer and peripheral parts, and increasing the stability of a control system. CONSTITUTION: A one-microcomputer control system of dual type A/V equipment for a vehicle includes a microcomputer(2) controlling a monitor, a monitor set-top connecting line(15) connecting the monitor and a set-top, an EEPROM(Electrically Erasable and Programmable Read Only Memory)(1) storing basic data, the set-top receiving a control signal from the microcomputer of the monitor for processing a signal, a clock/data communication line(21) connected to control the set-top by the monitor, a tuner(19) controlled by the microcomputer, and an expansion PORT IC(16) controlling other parts. |
