(EN) METHOD AND AN APPARATUS FOR DESIGNATING A RECORDING INTERVAL OF PICTURE DATA IN A DATA STREAM AND USING THE RECORDING INTERVAL, PARTICULARLY CONCERNED WITH RECORDING INFORMATION ABOUT AN INTERVAL OF A PICTURE LOADED IN A TRANSMISSION PACKET SEQUENCE WHEN RECORDING VIDEO DATA IN THE TRANSMISSION PACKET SEQUENCE, AND THEN DISCRIMINATING PICTURE DATA FROM THE RECORDED TRANSMISSION PACKET SEQUENCE ON THE BASIS OF THE INFORMATION

Abstract
(EN)

PURPOSE: A method and an apparatus for designating a recording interval of picture data in a data stream and using the recording interval are provided to generate management information about that a navigation unit for recording data is not arranged in a recording block having a certain size, generate management information classifying an interval of a preceding picture which belongs to one navigation unit, and record the management information.

CONSTITUTION: Video data are partitioned by a navigation unit, and are recorded as a plurality of recording blocks on a recording medium. Size information about preceding picture data in the partitioned each navigation unit are expressed as the number of transmission packets in which the picture data are sliced and included, and are recorded as management information of the corresponding navigation unit.

(KO) 본 발명은, 비디오 데이터를 네비게이션 단위로 구획하면서 복수의 기록블록으로 기록매체상에 기록할 때, 상기 구획된 각 네비게이션 단위내의 선두 픽처 데이터에 대한 크기정보를, 그 픽처 데이터를 슬라이스(slice)하여 포함하고 있는 전송패킷의 수로 표현하여 기록하거나, 상기 각 기록블록에 대해 그 선두에 128바이트의 헤더정보를 삽입기록하되, 만약, 특정 기록블록이 상기 구획된 각 네비게이션 단위내의 선두 픽처 데이터의 마지막 데이터를 포함하고 있으면 그 기록블록의 헤더정보내에 상기 끝지점을 나타내는 위치정보를 기록한다. 이로써, 각 네비게이션 단위내의 선두 픽처의 구간이 정확히 지시된다.
