Abstract
The present invention relates to an information processing apparatus and method which make it possible to transmit image data with high quality and low delay. A wavelet transform unitapplies wavelet transform to image data using a reversible filter that performs data transform with a reversible method that completely ensures forward direction and backward direction transform. An entropy coding unitencodes coefficient data using a predetermined entropy coding scheme, with a reversible method that completely ensures forward direction and backward direction transform. The present invention is applicable to, for example, an encoding apparatus or a decoding apparatus.
