Video encoding/decoding Apparatus and Method using second prediction based on vector quantization, and Recording Medium therefor

摘要

PURPOSE: A video encoding/decoding apparatus, method thereof, and recording medium through vector quantization base second prediction are provided to increase the efficiency of compression through vector quantization base second prediction. CONSTITUTION: A first prediction error signal generating unit(210) generates a first prediction error signal. A second prediction determining unit(240) determines the second prediction of a block unit. A center value generating unit(250) performs vector quantization of a first prediction error signal. A second prediction error signal generating unit(260) generates a second prediction error signal about a target block. An encoding unit(290) encodes a first quantized signal or a second quantized signal.
