PROBLEM TO BE SOLVED: To return to a reproduction output possible state at an appropriate timing even when data are omitted during data transfer by calculating time stamp data to be included in an omitted packet at the time of detecting data packet omission on a reception side and determining a data reproduction output timing thereafter by using them. SOLUTION: When a data packet transferred during a certain cycle period is omitted, a packet omission detection part 45 on the side of a receiver 12 generates detection signals and sends them to a time stamp data calculator 44 and a changeover switch 46. Though the sample data can not be reproduced and are lost by the omission of the data packet, time stamp difference data are obtained in a difference detector 43. By them and the time stamp data of this time of a first buffer 41, the time stamp data calculator 44 calculates calculation time stamp data and sends them to a matching detection circuit 34. Then, when the input of the matching detection circuit 34 and the count of a cycle timer 33 match during the next cycle, reproduction reference clock signals are outputted. |
