<P>PROBLEM TO BE SOLVED: To solve the problem that since time information for generating the time stamp of a GOV and time information for generating a time stamp are asynchronous, they may be shifted and should be corrected, and when a carry timing in a second of a VOP is delayed, borrow in a second is generated in a GOV, and since modulo_time_base is 1 in the next frame, another second is added, and it seems that two seconds are advanced in the period of 2 frames, and that since two time information is asynchronous as mentioned above, it seems that time is advanced by another extra second. <P>SOLUTION: This data compressor is provided with a first time stamp of one second unit, a time stamp adding means for adding the second time stamp of one or less second unit and a time stamp correcting means for correcting the second time stamp to a value which is a predetermined threshold or more when at least borrow in a second of the first time stamp is generated. <P>COPYRIGHT: (C)2007,JPO&INPIT |
