Abstract
PURPOSE: To ensure the automatic correction of the slice level in accordance with the state of the received signal and thus to carry out the accurate waveform shaping, by feeding the upper and lower level detection output of the start signal back to the amplification process circuit of the information signal.
CONSTITUTION: The TV signal including the static picture signal and others obtained through reception circuit 1 undergoes correction 26 for the local shift, the compensation of the phase and then correction of amplitude through amplitude correction circiut 29, and furthermore receives clamping through pedestal clamp corcuit 30 so that lower level l' may be changed to fixed level l. Thus, signal A featuring constant amplitude and DC level is obtained to then undergoes waveform shaping 33. In other words, the upper end level or upper level U' of the part of start signal STX is detected via upper level detecting circuit 31 among the information signals of the output of circuit 30, and then fed back to circuit 29. Then the amplitude of the information signal is controlled so that the upper level of the information signal is changed to constnat level U at all times. In the same way, the detection output is fed back to circuit 30 in the case of the lower level as well to turn the lower level to constant level l
