Abstract:
An audio encoding transmission system in which a transmitting station transmits audio signals in an encoded form onto a transmission line so that a receiving station receives, decodes and reproduces the audio signals, the audio encoding transmission system employing a method comprising the steps of:partitioning an encoded output corresponding to a result of an encoding process which the transmitting station performs on the audio signals into outline data having a low bit rate by which the audio signals can be successively reproduced and detail data which are combined with the outline data to provide a high sound quality in reproduction of the audio signals;transmitting the outline data prior to transmission of the detail data;then transmitting the detail data;performing successive reproduction of the audio signals by performing successive decoding of the outline data at the receiving station without waiting for the transmission of the detail data; andif both of the outline data and the detail data are completely transmitted to the receiving station, performing composition of the outline data and the detail data to provide high-quality reproduction of the audio signals.
