Packet data for a vehicle radio transmitting and receiving system control method and a recording medium

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packet data control method for a vehicle radio transmission / reception system and a recording medium therefor. To this end, the image transmission of a transmitter installed in the rear of a large lorry is divided into an image compression data unit, a digital interface unit, a digital to analog converter (D / A), a power amplifier (PA) Sending radio frequency data to a receiver; The receiver installed in the driver''s seat of the lorry is equipped with a switch contact point, a low noise amplifier (LNA), an analog to digital converter (A / D), a digital interface unit and an image compression data unit. step; And the Low Noise Amplifier (LNA) checks the value of Received Signal Sensitivity Indicator (RSSI) and confirms a threshold value of packet data using frequency hopping. The present invention configured as described above minimizes interference and confusion caused by wireless signals using similar frequencies in the vicinity of a wireless rear camera system for a vehicle and provides security for avoiding confusion with products using the same kind of products or similar products This technology maximizes the safety and convenience of the driver when the vehicle is backed up. This greatly improves the quality and reliability of the system, so that the user''s various needs Needs), so that it can give a good image.
