    摘要: An optical disk recording thereon compressed moving picture data and an optical disk reproduction apparatus each capable of easily effecting trick play such as high speed reproduction and a retrieval operation at a high speed. Additional information necessary for trick play is recorded in an arbitrary area of an optical disk such as a TOC (Table of Contents) or a leading sector (sector 0) of the disk, and a sector address is added to each sector. To conduct trick play, an I picture, a P picture and a B picture contained in a GOP layer inside a bit stream of compressed image data are extracted and reproduced in accordance with a reproduction speed by looking up a trick play table.

    摘要: In a system recording compressed video and audio signals or computer user data on a disk in the sector unit, to reproduce the data in a simple fashion at a high speed, data to be recorded on the disk is divided into data in a predetermined unit so as to add a first error correction (C1) code to each of the resultant data, which form (C1) correction blocks. Sectors are produced each including a plurality of (C1) correction blocks. Added to each (C1) correction block is a code enabling identification of a sector. To all data in the plural (C1) correction blocks, a second error correction (C2) code is added to record the resultant data on the disk to allow interleaving or deinterleaving completing in a block. The capacity of each sector is set to be substantially equal to that of a plurality of transport packets.
