ABSTRACT:
An auto-detection circuit for detecting video signals includes a reception end for receiving a video signal, a synchronization signal detector coupled to the reception end for generating a waveform according to voltage variation of the video signal, a peak value detector coupled to the synchronization signal detector for determining peak value of the wave form, a direct current voltage level switch coupled to the peak value detector for switching output voltage as first direct current voltage level or second direct current voltage level, and an output end coupled to the direct current voltage level switch for outputting the output voltage.
