PURPOSE:To attain proper audio switching control automatically in response to the broadcast audio mode by allowing an audio switching decision means to control an audio switching means depending on the result of decision of a broadcast audio mode deciding means. CONSTITUTION:An audio switching decision means 14 controls an audio switching means 15 depending on the result of decision of a broadcast audio mode deciding circuit means 13 to output a sound for front left speaker to a 1st output, to output a sound for front right speaker to a 2nd output, to output a sound for front center speaker or added sound for front left and right to a 3rd output and to output a sound for rear center speaker or added sound for front left and right to a 4th output respectively at all times. Thus, the output of the same sound output in the front speaker sound mode and the rear speaker broadcast sound mode is avoided. Thus, proper sound switching control is implemented automatically in the broadcast sound mode. |
