<P>PROBLEM TO BE SOLVED: To provide a synchronization method of real time data which is realized by a small-scale apparatus without using PLL, and reduces the power consumption by making additional data such as time stamp unnecessary. <P>SOLUTION: When audio/visual data sampled by a first sampling clock C101 are transmitted from a first terminal 100 to a second terminal 109, the speed of the second sampling clock C102 of the second terminal 109 is controlled based on the data amount of encoded data or the number of frames of the encoded data or the data amount of decoded data of the second terminal 109, and thereby the second sampling clock is adjusted. After being converted to data of a fixed third sampling clock S103 through a sampling rate converter (SRC) 114, the audio/visual data are converted to analog data in a DA converter 115 . <P>COPYRIGHT: (C)2005,JPO&NCIPI |
