Abstract: PROBLEM TO BE SOLVED: To suppress degradation of digital information to the utmost in decoding digital information embedding encoding specified information by providing an encoding means or the like for encoding encoded unit information in which the specified information is embedded and other encoded unit information, respectively. SOLUTION: Moving picture information of areas A to D in a memory 102 is sequentially transmitted to an encoding circuit 106, encoded there and encoding data of encoded moving picture information are transmitted from an area (a) to area (d) in a memory 109. Then, in an encoding amount comparison circuit 108, a block which has the largest total encoding amount of the blocks A to D is determined and a signal 117 for indicating an area of the memory 109 which stores the encoding data in the block is transmitted to a memory address control circuit 110. In this way, electronic watermark information can be embedded in the moving picture information of the encoding unit block where the amount of encoding becomes the maximum of the blocks A to D and degradation of digital information can be suppressed in decoding embedding encoded information.
