PURPOSE:To surely detect synchronism even if disturbance is added and to prevent the estimation error of synchronous timing. CONSTITUTION:Reproduction is executed at timing by a first timing estimation means 31 in a normal state. When it is judged that disturbance is added, a second timing estimation means 32 is operated by timing predicted in a prediction part 41 based on timing information in the past normal state in a timing buffer 9. Reproduction is executed at timing by the second timing estimation means 32 instead of the first timing estimation means 31. |
