Abstract: PURPOSE: A time stamp allocation method for a video service having non-increasing frame order is provided to automatically calculate a time stamp by using a frame indicator when a video of a hierarchical frame rate structure is encoded. CONSTITUTION: A plurality of frames that are decoded in a non-increasing frame order based video encoding method is received.

The time stamp of the calculated current frame is stored according to the frame rate indicators. All time stamps are deleted if the current frame rate indicator is equivalent to the maximum frame rate(S460).
