摘要

"Transmission device for transmitting a signal of digital information, receiving device for receiving a signal from the transmission case to transmit a digital information signal and a representation of the signal parameter via a transmission medium, its support of gra Vation, and apparatus ".A transmitter is provided to transmit a digital information signal via a transmission medium. The digital information signal is compressed in a coded signal and data of coefficient. The data of the coefficient are predicted, producing a signal prediction. The data of coefficient and the prediction signal are combined into a data signal.Both the coded signal as the data signal are transmitted via the transmission medium.
