ABSTRACT:
The digital information encoding apparatus comprises a context generation means for extracting a reference picture element from an inputted picture data, a context storage means for temporarily storing said context, a context table storage means comprising a read address input node, a read/write context table storing portion, a data output node, a write address input node and a data input node, a probability estimating table storage means comprising an address input node for receiving a probability estimation index in a probability estimating data, and a data output node which outputs a probability estimating data, and an arithmetic calculation means for receiving a picture data to be encoded and for outputting a renewal data including both the prediction symbol and the probability estimation index to said context table storage means.
