ABSTRACT:
A method and an apparatus for transmitting a video signal. A two-dimensional picture formed by the video signal is divided into a plurality of extracting periods, frames, fields, and areas. A first signal portion represents a moving area. The plurality of areas for each unit extracting period corresponding to successive N (N being a natural number) frames of the video signal. An extracted video signal is formed by extracting from one field the first signal portion in a moving area, and from another field second signal portions representing nonmoving areas. A position identification signal which indicates the position of the moving area formed by the first signal portion are transmitted in combination.
