Design And Study Of Car-Mounted Multimedia Audion-Visual System

This paper takes the focus on the development and design of a car-mounted multimedia audion-visual system. The system has independent intellectual property righto It is car-mounted TV, RADIO, VCD, DVD, MP3, CCD, TFT display and audio system all functions roled into one, moreover may connect with GPS , GIS, MP3, vidicon and hard disk recorder directness and use.The system adopts 32-bit multimedia chip Virgine G2 CPU. Each device interface circuit, communication interface circuit and overlap display circuit of image, graph and character are developed.Interactive function software with Chinese suggestion, device drive interface software and communication interface software are devised in EISC STUDIO development environment.Through design, experiment and improvement, car-mounted multimedia audion-visual system of complete software/hardware functions is devised 。 It realizes connect-conformity and controlment for input/output of car-mounted audion-visual devices. Prototype of a machine loading and testing and car-mounted audion-visual devices active system are producedo The system is steady, operation is convenient, cost performance ratio is high, operating state interface is good. Good pictures, personality icons are displayed quickly.
