ABSTRACT:
An encoder adds an identifier, being different when the coding should be done or not, into a predetermined location in an original signal, while a decoder reads out the identifier added and detects the condition of coding, so as to decide the execution (ON) of the decoding process to be done or not, automatically. Further, in each of the encoder and the decoder, there is provided a delay output portion, which provides an output treated with only a specific delay but not executing the coding/decoding thereon, separately from a coding process portion or a decoding process portion, wherein a selection can be made, at which one of the signals from the respective process portions and the delay output portion should be outputted, by a setup in an outside operation system with use of a selector.
