Abstract: A receiving apparatus including first and second tuners for receiving telecast signals and demodulating the signals of predetermined channels; a decoder for extracting the character broadcast data from either of the demodulated signals and decoding the extracted data; a selector switch for selecting either of the signals obtained from the first and second tuners and supplying the selected signal to the decoder; a controller for controlling the selector switch during its selection of the output signal from the second tuner in such a manner as to force the switch to periodically select the demodulated signal outputted from the first tuner; and a detector for detecting whether the character broadcast data extracted by the decoder represent a caption or not when the switch has selected the output signal from the first tuner; wherein, if the result of the detection by the detector signifies that the character broadcast data represent a caption, the controller forces the switch to select the output signal from the
