Abstract
A method and an apparatus for encoding key value data of an orientation interpolator representing the rotation of an object in a keyframe image are provided. The apparatus includes a rotational differential data generator which generates, using a rotational transformation value of a current keyframe and a restored rotational transformation value of a previous keyframe, a rotational differential value used to rotate the object by as much as a difference between rotational transformation applied to the object in the current keyframe by key value data and rotational transformation applied to the object in the previous keyframe by key value data, and outputs rotational differential data by quantizing the rotational differential value, a circular DPCM operator which selectively performs a linear DPCM operation or a circular DPCM operation on rotational differential data, and an entropy encoder which entropy-encodes the rotational differential data.
