Abstract
An apparatus for recording/reproducing image data according to MPEG2 system is provided which obtains I picture data reliably and performs trick playback smoothly. In the apparatus, a PES packet including an I picture is detected from video coded data which is recorded on a recording medium 30 by an I picture detection unit 5, an index file of the number of bytes from the start of recording or packet length and the like is created for the PES packet including the I picture data by a index file creation block 7, and the index file is recorded on an A/V-HDD 1 (10). In the trick playback process, a navigation control block 22 obtains the index file, and then obtains the I picture data from the PES packet on the basis of the index file, thereby to perform the trick playback smoothly.
