Summary:A multiple signal processing system is disclosed. The multiple signal processing system comprises an input signal converting unit for receiving multiple TMDS signals and converting the received TMDS signals into TTL level signals that are easy to perform scaling and image processing; an input scaling unit for receiving the TTL level signals from the input signal converting unit and adjusting a resolution of respective TTL level signals; a synchronization unit for generating a synchronization signal; a frame buffer unit for storing signals whose resolution has been adjusted by the input scaling unit and outputting the resolution-adjusted signals at the same time according to the synchronization signal generated by the synchronization unit; a processing unit for matching signals from the frame buffer unit to each of a plurality of output ports and outputting the matched signals; an output scaling unit for adjusting the resolution of the signals processed by the processing unit and matched to each of the output ports to be suitable for a display of the final end; and an output signal converting unit for receiving the signals whose resolution has been adjusted by the output scaling unit and converting the received signals into TMDS signals. The present invention can process multiple video signals and display them through a plurality of divided screens. Further, the present invention can eliminate a screen break phenomenon at the time of image switching and display composite images. 다중 신호 처리 시스템이 개시된다. 이러한 다중 신호 처리 시스템은, 다중의 TMDS 신호들을 입력받아 스케일링 및 영상 처리에 용이한 TTL 레벨의 신호들로 변환하는 입력신호 변환부와, 상기 입력신호 변환부로부터의 TTL 레벨의 신호들을 입력받아 각각의 TTL 레벨의 신호들의 해상도를 조절하는 입력 스케일링부와, 동기화 신호를 발생시키는 동기화부와, 상기 입력 스케일링부에 의해 해상도가 조절된 신호들을 저장하고 상기 동기화부에 의해 발생되는 동기화 신호에 따라 상기 해상도가 조절된 신호들을 동시에 내보내는 프레임 버퍼부와, 상기 프레임 버퍼부로부터의 신호들을 복수 개의 출력 포트들 각각에 매칭시켜 출력하는 처리부와, 상기 처리부에 의해 처리되어 출력 포트들 각각에 매칭된 신호들을, 최종단의 디스플레이(DISPLAY)에 적합하도록 해상도를 조절하는 출력 스케일링부와, 상기 출력 스케일링부에 의해 해상도가 조절된 신호들을 입력받아 TMDS 신호들로 변환하는 출력신호 변환부를 포함한다.
