1. An information processing apparatus that encodes image data, comprising:

  • comparison means for comparing frames or fields constituting image data in increments of a line block including image data equivalent to a number of lines needed to generate coefficient data equivalent to one line of sub-bands of at least lowest frequency components;

    generation means for generating concealment information indicating a method of concealing an error in a line block in accordance with a comparison result obtained by the comparison means;

    encoding means for generating encoded data by encoding coefficient data reordered in advance in the order in which the coefficient data is used in executing a combining process of combining coefficient data of a plurality of sub-bands decomposed in frequency bands to generate image data; and

    control means for controlling the encoding means so as to multiplex the concealment information generated by the generation means with the encoded data generated by the encoding means.
