PROBLEM TO BE SOLVED: To realize a synchronous mechanism by utilizing data subjected to high efficiency (compression) coding by a coding system having a reproduction speed conversion function as audio object data before moving image object data and audio object data both having an individual reproduction time are synchronized or before the moving image object data which are subjected to edit processing and the audio object data are synchronized. SOLUTION: After a video data edit section edits a video stream 1a, a video information detection section 4 detects a reproduction time of video after the edit and gives it to a speed parameter setting section 6. The speed parameter setting section 6 detects a reproduction time of the received audio object to decide a reproduction speed to be synchronized with the video reproduction time detected by the video information detection section. Decision contents are fed to an audio decoder 7, where the contents are decoded and again encoded according to contents subjected to speed conversion by an audio encoder 8. |
