Abstract
A compression-encoding method allowing any discrepancy such as a delay caused by a change in frame rate to be avoided is disclosed. It is determined whether a predetermined number of frames required for forming a GOP have been inputted and, when the predetermined number of frames have not been all supplied, a dropped frame is compensated for by interpolation of a proceeding frame previous to the dropped frame to produce an interpolated group of pictures. Each frame of the interpolated GOP is compression-encoded to produce encoded moving picture data to be stored into a memory.
