Abstract:
1. 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, each field formed in a 4:2:0 picture format, wherein said encoding encodes the motion picture signal according to a respective calculation method adaptively selected from a plurality of different calculation methods depending on parities of a reference field and a coding field so that a chroma motion vector is generated from a luminance motion vector and is in parallel with the luminance motion vector, and a first calculation method is employed by said encoding to encode the motion picture signal when both the reference and coding fields are a top field or both the reference and coding fields are a bottom field, a second calculation method is employed by said encoding to encode the motion picture signal when the reference field is the top field and the coding field is the bottom field and a third calculation method is employed by said encoding to encode the motion picture signal when the reference field is the bottom field and the coding field is the top field.
