Abstract

The invention relates to a car video and audio extension system with learning functions, a related car video and audio learning system and a method. The car video and audio system comprises a play mechanism, a main unit and an extension set. The play mechanism comprises a remote controller. The remote controller is provided with a first press key which generates a first control code when the first key is pressed. The main unit is provided with a second press key which generates the second control code when the second key is pressed. The extension set is coupled between the main unit and the play mechanism. In learning state, the extension set processes the first code and the second code to create a corresponding relationship. In operation mode, the second key on the main unit is pressed and the extension set generates a third control code according to the corresponding relationship which correspondingly controls the play mechanism.

Description

technical field [0001] The present invention relates to car audio-visual technology, in particular to a car audio-visual expansion device with a learning function, a car audio-visual system and a learning method using the same. Background technique [0002] When a vehicle leaves the factory, it is usually only equipped with a head unit and speakers. With the advancement of audio-visual technology, the audio-visual system has gradually expanded from the fixed environment of the home to the mobile environment of the car, and the user's demand for the expansion of the audio-visual system is very eager. Therefore, the inventor of the present application promptly discloses a kind of " car audio-visual device and its interface circuit that can expand the auxiliary signal source " in the No. 225478 case of Taiwan New Model Patent Certificate. It can expand and integrate one or more sets of auxiliary signal sources (auxiliary input) in the existing audio-visual system. However, fo...
