Abstract
Official abstract text for this publication.
When a prediction is made between fields with different parity, the predicative efficiency of a chrominance vector is improved by adaptively switching the generation of a chrominance motion vector depending on a encoding/decoding field parity (top/bottom) and a reference field parity (top/bottom), and the coding efficiency is improved accordingly.
First claim
Opening claim text (preview).
What is claimed is: 1. A motion picture decoding method for making an inter-field motion compensation prediction and executing a decoding process on a motion picture signal by using a motion vector, wherein each frame is composed of two fields being a top field and a bottom field, respectively, a reference field is the top field and a decoding field is the bottom field, a number of pixels of a chrominance vertical component is different than a number of pixels of a luminance vertic…
