A DEVICE AND METHOD FOR PROVIDING INTER-FIELD MOTION COMPENSATION FOR CHROMINANCE MOTION VECTORS WHILE DECODING MOTION PICTURES

摘要

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.
