Abstract

본 발명은 텔레비전 수상기 방송신호 송수신 시스템에 관한 것으로서, 더욱 상세하게는 방송국에서 송신하고 텔레비전 수상기에서 수신하는 방송신호에 타이틀 문자를 삽입하여 텔레비전 수상기의 전원공급시와 채널 절환시에 화면에 디스플레이하도록 한 타이틀 표시기능을 갖는 텔레비전 수상기 송수신 시스템에 관한 것으로, 송신하기 위한 타이틀 문자를 코오드회된 조합으로 변환하는 타이틀 문자엔코우더(12)와, 상기 방송신호에 타이틀 문자를 합성하여 변조부(14)에 인가하는 합성부(13)를 포함하는 방송국이 구성되고, 안테나(20), 동조 및 RF증폭부(21), IF증폭부(23), 영상검파부(24)로 수신된 영상신호로부터 타이틀 문자정보를 추출하는 타이틀 문자추출부(30)와, 상기 추출된 타이틀 문자정보를 저장하는 메모리(31)와, 전원 온 및, 동조 및 RF증폭부(21)의 채널절환상태시 메모리(31)에 저장된 타이틀 문자정보를 OSD문자처리부(33)를 통해 처리하여 영상신호와 함께 모니터(29)에 소정시간동안 디스플레이되도록 제어하는 제어부(32)를 포함하는 텔레비전 수상기가 구성된 것이다.The present invention relates to a system for transmitting and receiving broadcast signals of a television receiver, and more particularly, to insert a title character into a broadcast signal transmitted from a broadcasting station and received from a television receiver so as to be displayed on a screen when the television receiver is supplied with power and switching channels. A television receiver transmission / reception system having a title display function, comprising: a title character encoder (12) for converting a title character for transmission into a coded combination, and a modulator (14) by combining title characters with the broadcast signal; A broadcasting station including a synthesizing unit 13 to be applied to the broadcasting station is constructed, and a title is obtained from an image signal received by the antenna 20, the tuning and RF amplifier 21, the IF amplifier 23, and the image detector 24. Title character extraction unit 30 for extracting character information, memory 31 for storing the extracted title character information, power-on, tuning and RF amplifier unit And a controller 32 for controlling the title character information stored in the memory 31 through the OSD character processor 33 to be displayed on the monitor 29 for a predetermined time together with the image signal when the channel switching state of the channel 21 is performed. Is a television receiver.
