Abstract:
A TV set, comprising:a tuner circuit for selecting a channel and outputting video and audio signals of a selected channel;a first external output terminal for outputting said video signals;a second external output terminal for outputting said audio signals;a first external input terminal to which video signals from external AV devices are supplied;first switching means for selectively taking out video signals from said tuner circuit and video signals from said first external input terminal;second switching means operably associated with said first switching means and taking out audio signals from said tuner circuit when said first switching means selects said video signals from said tuner circuit;a display for displaying images of said video signals output from said first switching means;means for producing sounds of said audio signals output from said second switching means;means for controlling respective selecting states of said first and second switching means for allowing both said first and second switching means to select video signals from said first external input terminal; anda second external input terminal to which audio signals from said external AV devices are supplied,said audio signals supplied to said second external input terminal and said audio signals from said tuner circuit being selectively taken out from said second switching means,wherein said means for producing sounds includes an audio/video (AV) amplifier andsaid first and second external output terminals and said first and second external input terminals are connected respectively to input terminals and output terminals of said AV amplifier,video and audio signals fed to said first and second external output terminals are supplied to said first and second switching means via said first and second external input terminals, andaudio signals fed to said second external output terminal are processed in said AV amplifier, then supplied to external speakers.
