MPEG DECODE CIRCUIT PARALLEL DRIVE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide inexpensive parallel drive system that employs a plurality of MPEG decode circuits to obtain a composite image. ;SOLUTION: A decode start time obtained by tracing back a display time decided by a decoder display time decision means of an MPEG decode circuit is compared with a decode start schedule time calculated from time stamp information extracted from a transport stream signal. When the decode start time is slower than the decode start schedule time by a prescribed time or longer, it is confirmed that the concerned image is not a reference image required for decoding other image, a decoder is controlled to stop decoding the image and an MPEG decode circuit among plural of MPEG decode circuits informs the other MPEG decode circuit of the display time.;COPYRIGHT: (C)2001,JPO
