Abstract
The coded signal is output with a frame sequence that differs from the frame sequence of the input video signal by outputting the frame information coded by in-frame or inter-frame coding before the frame information coded bay interpolation coding based on the successively preceding frames. Frames immediately preceding a scene change are coded by a method other than field interpolation coding, frames immediately after a scene change are coded by in-frame coding, and the coded information for the frame immediately after the scene change is output after the coded information for the frame immediately before the scene change.
