Filed: 2002-12-31
Abstract: PURPOSE: A method for controlling an audio output of a home theater is provided to improve listening environment by re-adjusting an output level and timing of an audio signal outputted from a speaker. CONSTITUTION: Where a key signal for adjusting an audio output is inputted, a main controller(1) outputs a predetermined test audio signal to speakers(SP_CEN,SP_FL, SP_FR,SP_RL,SP_RR,SP_W). An audio level and an output timing of the predetermined test audio signal are set based on a setting table provided by a manufacture of a home theater. Each of the speakers(SP_CEN,SP_FL, SP_FR,SP_RL,SP_RR,SP_W) transforms the predetermined test audio signal to transmit it to a checker(2) through a radio channel. The checker(2) analyzes volume and delay time of the transmitted signal to send the analyzed result to the main controller(1). Then, the main controller(1) adjusts an output level and timing of an audio signal to be transmitted to each of the speakers(SP_CEN,SP_FL, SP_FR,SP_RL,SP_RR,SP_W).
