Abstract

MPEG 권고안에 의해 압축된 동화상데이타를 기록함에 있어 가변속재생(트릭플레이)를 용이하게 하는 기록방법이 개시된다.A recording method for facilitating variable speed playback (trick play) in recording moving picture data compressed by the MPEG Recommendation is disclosed.

본 발명에 따른 동화상데이타의 기록방법은 동영상부호화에 의해 압축된 I,B,P화면의 화상데이타를 일정한 데이터량을 기록할 수 있는 트랙들을 갖는 기록매체에 기록하는 방법에 있어서, I,B,P,화상이 점유하는 트랙수가 동일하게 함을 특징으로 한다.A method of recording moving picture data according to the present invention is a method for recording image data of I, B and P screens compressed by moving picture encoding onto a recording medium having tracks capable of recording a fixed amount of data. P, characterized in that the number of tracks occupied by the image is the same.

본발명은 B 및 P화상의 데이타를 I화상의 데이타와 동일한 수의 트랙에 기록하여 가변속 발생시 모든 화상데이타가 주기적으로 주사될 수 있게 함으로서 재생되는 화면에 일정한 패턴을 부여하는 효과를 갖는다.The present invention has the effect of giving a constant pattern to a picture to be reproduced by recording the data of B and P pictures in the same number of tracks as the data of I pictures so that all image data can be periodically scanned at the time of variable speed generation.

Claims (4)

동영상부호화에 의해 압축된 I,B,P화면의 화상데이탈 일정한 데이타량을 기록할 수 있는 트랙들을 갖는 기록매체에 기록하는 방법에 있어서, 상기 I,B,P화상이 점유하는 트랙수가 동일함을 특징으로 하는 동화상데이타의 기록방법.A method of recording on a recording medium having tracks capable of recording a constant amount of image data of an I, B, or P screen compressed by moving picture encoding, wherein the number of tracks occupied by the I, B, and P images is the same. Method for recording moving picture data, characterized in that. 제1항에 있어서, 상기 트랙수는 데이타량이 가장 많은 I화상을 기록하기에 충분한 정도로 선택되며, I화면의 화상데이타가 기록되는 트랙에는 I화면의 화상데이타만이 기록되고, 상기 B와 P화면의 화상데이타가 기록되는 기록트랙에는 각각에 기록도는 화면으로부터 추추된 DC성분을 포함하는 저주파성분의 화상데이타를 분산시켜 기록함을 특징으로 하는 동화상데이타의 기록방법.2. The image recording apparatus according to claim 1, wherein the number of tracks is selected to be sufficient to record the I image having the largest amount of data, and only the image data of the I screen is recorded on the track in which the image data of the I screen is recorded. And recording the image data of the low frequency component including the DC component inferred from the screen recorded on each of the recording tracks on which the image data is recorded. 제2항에 있어서, 상기 저주파성분의 화상데이타는 상기 B혹은 P화면을 구성하는 DCT변환블럭의 DC성분을 취하여 집합시킨 것임을 특징으로 하는 동화상데이타의 기록방법.3. The method according to claim 2, wherein the image data of the low frequency component is collected by taking the DC component of the DCT conversion block constituting the B or P screen. 제3항에 있어서, 상기 DC성분은 B 혹은 P화면 내의 각 매트로블럭의 DC성분과 이 매크로블럭을 정의하는 I화면의 매크로블럭의 DC성분을 가산하여 산출되는 것임을 특징으로 하는 동화상데이타의 기록방법.4. The method of claim 3, wherein the DC component is calculated by adding the DC component of each macroblock in the B or P screen and the DC component of the macroblock of the I screen defining the macroblock. . ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
