- Provided are an apparatus and method for predictive coding/decoding for improving a compression rate of multiview video using one or two additional reference frame buffers. The predictive encoding apparatus includes: a multiview reference picture providing unit for providing a reference picture for a predictive encoding according to temporal and spatial GOP structure information; a prediction unit for creating a vector by predicting which part of the reference picture inputted from the multiview reference picture providing unit is referred by a picture to currently encode; a transforming and quantizing unit for obtaining a difference signal between the predicted signal inputted from the prediction unit and a picture signal to currently encode, transforming the obtained difference signal, quantizing the transformed signal, and compressing the quantized signal; and an entropy encoding unit for encoding the quantized signal and the vectors according to a predetermined scheme and outputting the encoded signal.
