Übertragungsgerät und Verfahren wobei Kodierungsparameter vom Benutzer einstellbar sind

摘要

Disclosed is a communication apparatus in which coding and/or decoding parameters for coding and/or decoding data can be performed in dialog fashion to make possible the optimum coding of transmitted data and the optimum reproduction of received data. The apparatus includes a coefficient adjusting unit for adjusting coding and/or decoding parameters, and a decode-signal changeover unit for selecting, as an input signal to be decoded, one of a reception signal that has been received through a line and a transmission signal that has been coded, wherein the parameters are adjusted based upon the coded transmission signal. The apparatus further includes an image synthesizing unit for simultaneously displaying an input signal from input means and a decoded signal.
