Abstract

Abstract PURPOSE:To display a high definition television broadcasting by detecting the presence or absence of a pilot signal indicating the multiplex state of a high definition signal from a television signal. CONSTITUTION:The high definition signal is multiplexed on the high frequency part of a luminance signal in the TV signal of a high definition TV system and the pilot signal for discriminating the presence or absence of the multiplex state is inserted into the high definition TV signal. In a receiving side, the presence or absence of the pilot signal are detected by the use of a pilot signal detecting circuit 30. At the time of detecting the pilot signal, the received TV signal is decided to be the high definition TV signal So and the high definition TV broadcasting is displayed on a display device 21 according to the result. Consequently, the user of a TV receiver can discriminate effectively whether a currently received signal is the high definition TV signal or a current TV signal.
