Abstract

[목적][purpose]

헤드에 클럭이 발생하기도 하고, 스크러치가 생긴 경우에도, 보간을 행하기 쉽게한다.Even when a clock is generated in the head and scratches are generated, interpolation can be easily performed.

[구성][Configuration]

2개의 헤드의 재생신호를 2개의 프레임간의 화면상의 위치가 서로 다르도록 샤프링한다. 또, 대응하는 위치에 있는 각 컴포넌트 신호의 DDCT블럭을 모아서 슈퍼 마크로 블럭을 구성하고, 이 슈퍼 마크로 블럭 단위에서 샤프링을 행한다.The reproduction signals of the two heads are sharpened so that positions on the screen between the two frames are different from each other. The DDCT blocks of the component signals at the corresponding positions are collected to form a super macro block, and sharpening is performed in units of the super macro block.

Claims

A signal processing method of a segment recording method in which one screen is divided into a plurality of tracks and recorded, wherein the two head signals are sharpened so that positions on the screen between two frames are different from each other.

In a signal processing method of a segment recording method for dividing and recording one picture into a plurality of tracks, a DCT block of each component signal at a corresponding position is collected to form a macro block, and the adjacent macro blocks are further collected to form a super macro block. And sharpening in units of the super macro block.

In a signal processing method of a segment recording method for dividing and recording one picture into a plurality of tracks, one image of a digital video signal is divided into integers in the horizontal direction, and the vertical direction is divided into the number of recording tracks, and each of the plurality of marks is divided into a plurality of tracks. And a sub area including a block, and the sharpening is performed in units of the sub area.

The method according to claim 3, wherein a plurality of the macroblocks each taken out from the sub-area of each divided area are sharpened so as to maximize the distance between the sub-areas of the same number between the adjacent divided areas. Signal processing method to record to.
