摘要: At the transmitter a TV signal, an accompanying videotext signal and screen display control generated by separate circuits (1-3) are combined (4) into TDM digital for conversion (5) high-frequency transmission from antenna (7). The receiving (8) feeds tuner IF stage (9), picture processing circuit (10) memory (11), decoder (14) with which separates (S5) microprocessor (16) linked to remote receiver (15). memories read (S6,S7) selectively presentation (12) of three-colour images text in areas on (13).
