Abstract
본 발명은 고화질티브이의 비월주사 변환장치에 관한 것으로, 종래 고화질티브이장치의 신호원은 순차주사방식으로서 광대역 신호의 영상신호를 브라운관에 디스플레이 함으로써 수직, 수평방향으로 2배이상의 해상도를 구현할 수 있으나 고화질 티브이의 수평, 수직 해상도를 2배이상 실현하기 위해서는 대역폭이 현행 티브이의 4배이상 소모되어 고속의 게이트 및 광대역 씨티프엠프, 높은 발진을 요하는 파워서플라이, 고성능 수직, 수평편향회로등이 적용되어야 하므로 원가 상승을 초래한다. 또한 고화질 티브이의 디스플레이 방식을 대형 모델에 적용하면 고해상도의 효과가 잘 나타나지만 소형이나 중형모델(30인치이하)에 적용하면 수직해상도와 수평 해상도가 광대역을 사용하지 않은 것과 비교하여 그렇게 차이가 나지 않는다.이는 소형이나 중형에서 고화질티브이의 고해상도신호를 순차주상방식으로 적용하면 해상도가 증가한 디스플레이를 하지 못하게 되어 원가상승만 초래하는 단점이 있었다. 본 발명은 이러한 문제점을 해결하기 위하여 소형이나 중형에서는 순차주사방식 대신에 비월비주방식을 적용하여 순차방식을 적용한 해상도와 거의 동일한 해상도를 얻도록 하는 것으로 소형이나 중형의 고화질 티브이는 비월주사방식의 저렴한 시스템으로 구성토록 하는 것이다.The present invention relates to an interlaced scanning converter of high-definition TV, and the signal source of the conventional high-definition TV is a sequential scanning method, and can realize a resolution of twice or more in the vertical and horizontal directions by displaying an image signal of a broadband signal on a CRT. In order to realize more than twice the horizontal and vertical resolution of TVs, bandwidth is consumed more than 4 times of current TVs, so high-speed gates and wideband amplifiers, power supplies requiring high oscillation, and high performance vertical and horizontal deflection circuits must be applied. As a result, cost increases. In addition, the high resolution TV display method is applied to a large model, the effect of high resolution is shown well, but when applied to a small or medium model (30 inches or less), the vertical resolution and the horizontal resolution are not so different compared to those without using broadband. This is because when the small and medium sized high-definition signal of high resolution is applied to the sequential column method, it is impossible to display the increased resolution, which leads to a cost increase. In order to solve this problem, the small and medium sized high-definition TVs are inexpensive in interlaced scanning. To be configured as a system.
