Claims (1)

소정의 수평 및 수직 2차원 공간 주파수 영역을 지니는 넓은 아스펙트 화면비의 인터레이스 주사 텔레비전 신호를 좁은 아스펙트 화면비를 갖는 좁은 화면 텔레비전 신호와 그것을 초과하는 화면부에 관한 초과화면 텔레비전 신호로 분리하고, 상기 초과 화면 텔레비전 신호가 상기 좁은 화면 텔레비전 신호의 2차원 공간 주파수 영역의 경사 고역 주파수 영역으로 영역 압축되어서 다중화 되어 송신되는 텔레비전 신호를 받는 입력수단(41)과; 이 입력수단(41)으로 수신된 수신 텔레비전 신호에서 상기 좁은 화면 텔레비전 신호를 추출하는 좁은 화면 텔레비전 신호 추출 수단(42); 상기 수신 텔레비전 신호로 부터 영역 압축된 상기 초과화면 텔레비전 신호를 추출하는 초과 화면 텔레비전 신호 추출 수단(44)과; 이 추출 초과화면 텔레비전 신호의 영역을 소정의 수평 및 수직 2차원 공간 주파수영역으로 복원하는 주파수 영역 복원 수단(44)과; 상기 좁은 화면 텔레비전 신호 추출 수단(42)에서 추출된 상기 좁은 화면 텔레비전 신호 좁은 화면 및 상기 주파수 영역 복원 수단(44)으로 복원된 상기 초과 화면 텔레비전 신호를 합성하는 화면 합성 수단(49)을 구비하는 것을 특징으로 하는 넓은 화면비 텔레비전 신호 수신 장치.An interlaced scanning television signal having a wide aspect ratio having a predetermined horizontal and vertical two-dimensional spatial frequency region is separated into a narrow screen television signal having a narrow aspect ratio and an overscreen television signal with respect to a screen portion exceeding the above. Input means (41) for receiving a television signal in which a screen television signal is region-compressed and multiplexed and transmitted into an inclined high frequency region of a two-dimensional spatial frequency region of said narrow screen television signal; Narrow screen television signal extraction means (42) for extracting the narrow screen television signal from the received television signal received by the input means (41); Excess screen television signal extracting means (44) for extracting said overscreen television signal that has been region compressed from said received television signal; Frequency domain restoring means (44) for restoring the region of the extracted over-screen television signal to a predetermined horizontal and vertical two-dimensional spatial frequency region; And a screen synthesizing means 49 for synthesizing the narrow screen television signal narrow screen extracted by the narrow screen television signal extracting means 42 and the excess screen television signal restored by the frequency domain restoring means 44. A wide aspect ratio television signal receiving apparatus. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
