<P>PROBLEM TO BE SOLVED: To solve problems of reproducing apparatuses of prior arts that the reproducing apparatus without a special purpose PLL circuit has limitations in AV synchronization having been used so far and that the algorithm of the reproducing apparatus of prior arts utilizes only information of Time Stamp but does not utilize multiplexed clock information and the application scope of the reproducing apparatus is much more restricted because the algorithm is to be designed to work under the assumptions that at least either of Audio and Video is in normal operation and there exists a means capable of acquiring time information of Frames under reproduction at present. <P>SOLUTION: In order to overcome the problems above, a software program adopting an AV synchronization algorithm is newly developed so as to be capable of utilizing the multiplexed clock information thereby making an error grasping method independent of a particular reproduction object and improving the accuracy of the synchronization. <P>COPYRIGHT: (C)2007,JPO&INPIT |
