Abstract

본 발명은 화면의 가로 대 세로의 비율이 16:9인 CPT에 가로 대 세로의 비율이 4:3인 하나의 주화면과, 이 주화면의 외측에 가로 대 세로의 비율이 4:3이고 주화면의 크기보다는 작은 3개의 부화면을 표시하는 것으로서 종래의 영상 처리회로를 CPT에 4개의 화면을 표시할수 있으나, 입력되는 4가지의 영상중에서 선택된 2가지의 영상만을 표시하므로 시청자들은 4가지 영상의 화면을 모두 동시에 볼수 없음은 물론 CPT에 표시되는 않은 영상을 확인할 경우에는 일일이 키보드부를 조작하면서 선택스위치를 스위칭시켜야 되어 사용자에게 많은 번거로움을 주었다.According to the present invention, a main screen having a aspect ratio of 4: 9 to a CPT having a 16: 9 aspect ratio of a screen, and a aspect ratio of 4: 3 having a aspect ratio of 4: 3 outside the main screen It displays three sub-screens smaller than the size of the screen, and the conventional image processing circuit can display four screens on the CPT. However, since only two images selected from the four input images are displayed, viewers can display four images. Not only do not see all the screen at the same time, but also check the video that is not displayed on the CPT, it was a hassle for the user to switch the selection switch while operating the keyboard part.

본 발명은 3개의 POP색복조부를 구비하고, 이들 POP색복조부에 부화면 신호, 제1의부신호 및 제2외부신호를 선택적으로 입력시킬수 있도록 하여 4가지의 영상을 모두 동시에 CPT에 표시함은 물론 3개의 부화면을 동화면 또는 스트로브 기능으로 표시할수 있다.The present invention includes three POP color demodulators, and the POP color demodulator can selectively input the sub-screen signal, the first sub-signal and the second external signal to display all four images simultaneously on the CPT. Three sub-screens can be displayed with the dynamic screen or strobe function.
