Abstract: In a prediction method usable with synthetic and natural hybrid coding (SNHC) field or a virtual reality markup language (VRML) the difference between immediately prior information (most adjacent information) and input property information is obtained, considering the immediately prior information as the prediction value. The difference is used as a prediction error signal. A predictor having an order of 1 is used. When the output value of the predictor is fixed to 0, the prediction error signal becomes identical to an original signal. Therefore, the operation is the same as in the case where there is no predictor. The correlation of the input property information is used in order to control two operation modes of the predictor. Namely, auto-correlation is obtained from the input property information.
