Abstract
An encoded data modification device and the like are obtained which are capable of modifying a signal with a small delay. There is provided the encoded data modification device, including: an operational buffer that stores inputted encoded data formed of a plurality of encoded units; a decoder circuit that decodes the encoded data stored in the operational buffer; a modification circuit that modifies a first encoded unit of the decoded data and modifies following decoded encoded units according to the modification; an encoder circuit that re-encodes the modified data; an operational circuit that judges whether the modification is contained in the data in the buffer; and a write control circuit that rewrites the encoded data stored in the operational buffer to the data modified by the modification circuit and re-encoded by the encoder circuit when the operational circuit judges that the modification is contained in the data in the buffer.
