Abstract:
1. A predictive encoding apparatus using a view-temporal reference picture buffer, comprising: a multiview reference picture providing unit for providing a reference picture for a predictive encoding according to temporal and spatial group of picture (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 from the transforming and quantizing unit and the vectors provided from the prediction unit according to a predetermined scheme, and outputting the encoded signal, wherein the multiview reference picture providing unit includes: a restored picture storing unit for storing and outputting restored pictures of a current viewpoint and a different time; a first adjacent viewpoint reference picture storing unit for storing and outputting restored pictures of an adjacent viewpoint and a current time; a two adjacent viewpoint reference picture storing unit for storing and outputting restored pictures of an adjacent viewpoint and a different time; a viewpoint transforming unit for transforming an adjacent viewpoint picture inputted from the first and second adjacent viewpoint reference picture storing units to a current viewpoint picture according to previously inputted camera information; and a reference picture selecting unit for selecting one of the pictures inputted from the restored picture storing unit and the viewpoint transforming unit as a reference picture according to temporal and spatial GOP structure information inputted from the GOP information generating unit.
