Aufzeichnungsverfahren für komprimierte und kodierte Daten

摘要

A method of recording compressed and coded data is designed to improve the speed and easiness of random accessing, and to reduce the buffer capacity and facilitate control and edition in the reproducing system. The method comprises the steps of compressing and coding video signals for every predetermined number of frames with the amount of codes per the predetermined number of frames being constant; storing the predetermined number of frames of compressed and coded video signals into at least one video packet; storing the video packet in a pack having a time slot corresponding to the predetermined number of frames (desirably at the end of the pack); and recording the video signals on the recording medium in a pack stream containing such packs, with the relation between the size of the pack and the size of the logical block of the recording medium being set to 1 : n (n: an integer) and the relation between the size of the pack and the size of the physical block of the recording medium being set to 2 : n.
