Patent ID: 8665956

Claim:
A motion picture encoding method comprising: encoding, by an encoder, a motion picture signal composed of a plurality of fields with an inter-field motion compensating prediction so that: MVC y =MV y −2 when a reference field is a bottom field and a coding field is a top field, wherein MV y implies a vertical component of a luminance motion vector indicating a vertical direction movement of a luminance pixel of a field image, and vector component values of the luminance motion vector are displaced by a value of 4, and MVC y implies a vertical component of a chrominance motion vector indicating a vertical direction movement of a chrominance pixel of the field image, and vector component values of the chrominance motion vector are displaced by a value of 8, so that the chrominance motion vector and the luminance motion vector are thereby parallel, and a motion vector is a vector that connects two corresponding pixels between a coding field and a reference field.
