ABSTRACT:
A method and apparatus for reproducing normally a picture of a recording system by operating the recording system and a display system asynchronously, and by holding and/or skipping a picture frame or field of the display system. The method for extending and reproducing compressed moving pictures includes asynchronizing data transferring a clock from a recording unit with a display system clock and then setting a hold or skip threshold which is in advance of a recording system time by a first predetermined frame (field) time. A timing is corrected by holding or skipping the display system time for one frame (field) when a display system time becomes equal to the hold or skip threshold. Frames (fields) of the display system which are closest to the recording system time are then displayed when the display system time is held or skipped for the one frame (field).
