Receiving apparatus and receiving method

An apparatus for receiving telecast signals where character broadcast data is superimposed as teletext data, said apparatus comprising:

• first and second receiving means each for receiving said telecast signals, for demodulating said telecast signals of predetermined channels, and for outputting respective demodulated signals;
• decoder means for extracting said character broadcast data from one of said demodulated signals outputted respectively from said first and second receiving means, decoding the extracted data, and outputting a decoded data;
• output means for selectively delivering as an output one of the outputs of said first and second receiving means and said decoder means, or combining two of the outputs of said first and second receiving means and delivering a combined output as the output;
• selector means for selecting one of said demodulated signals from said first and second receiving means and supplying a selected signal to said decoder means;
• control means for controlling said selector means during its selection of said demodulated signal outputted from said second receiving means so as to force said selector means to periodically select said demodulated signal outputted from said first receiving means;
• and
• detector means for detecting whether said character broadcast data extracted by said decoder means represents a caption when said selector means has selected said demodulated signal outputted from said first receiving means, wherein when said detector means detects a caption, said control means controls said selector means to select said demodulated signal outputted from said first receiving means.
