摘要

By sending the encoded data of one, to provide a decoding result differs depending on the presence or absence of change information integrated with the encoded information to share the receiving side. 'The encoding unit 505 encodes the output' modeling unit 502A to obtain the parameters 504 and data value 503 by modeling the data string 501 and input, equipped with a signal transmission unit 506 'for transmitting the output In the configuration, and changing operation instructing setting changing unit 523A based on the change information 521 the value of one of the parameters a) data, b─2 or data operation section 530A, and outputs it to the coding section by manipulating the setting changing unit is based on the information indicating change any of the parameters or data value 504 503 b─1) modeling unit outputs After the setting change unit has operated on the basis of indicating change information to the transmitting code output to either obtain a coded result of the change by changing operating instruction predetermined) coding unit, signal transmission unit transmits the transmission I was equipped with, at least any one of b─2) sign the operating section of the sign operation section 531A to do, or above b─1) data operation unit. It was also a corresponding decoder.
