摘要： An encoding/decoding apparatus and method for an orientation interplator node are provided. The encoding/decoding apparatus for an orientation interpolator node, which provides rotational information of an object in a 3-dimensional space, is formed of “key information” which indicates a time when a rotational movement occurs and “key value information” which indicates a rotational posture corresponding to the time. A predictive coding apparatus is used in the encoding process for compressing the information of the key and key value information. Therefore, in encoding an input orientation interpolator node in an information compression method of a predictive encoding method, the efficiency of encoding is improved and an reverse rotation due to an encoding error from lossy coding can be corrected.
