<p>PROBLEM TO BE SOLVED: To provide an image signal reproducing device wherein error resistance is increased by improving faster recovery from an error and the accuracy of determining a synchronous reproducing error with respect to the error of inputted coded data in the reproducing of a multiple signal such as an audio, a video, a caption or the like. SOLUTION: A unique pattern is detected, header section analysis is performed by determining whether a subsequent pack or packet identifier is an effective packet or not, reproducing time information contained therein is accumulated, and control is performed to transfer coded data in the packet to a decoding buffer or jump-reading it. When error determination is made by a packet identifier error determining device 2s12, an input processing control means 2s6 controls a unique pattern detector 2s3 without actuating a header analyzing section 2s4 so as to perform unique pattern detection indicating the head of the new pack and packet.</p> |
