METHOD AND APPARATUS FOR ENCODING AND DECODING VIDEO SIGNALS IN INTRA-BASE-LAYER PREDICTION MODE BY SELECTIVELY APPLYING INTRA-CODING

摘要

A method and apparatus for encoding and decoding macroblocks in an intra-base layer prediction mode by selectively applying intra-coding are provided. The method includes the steps of calculating a difference between an input frame and a base layer frame calculated from the input frame and obtaining residual signals, converting the residual signals using an intra-coding method, and generating an enhancement layer frame including the converted residual signals.
