Abstract

PURPOSE:To enable smooth voice reproduction even with a reception error, by replacing the data of normal packet immediately before the data with reception error with an error packet data. CONSTITUTION:A packet decomposer PD starts packet data assembly from the readout of the NO.1 packet, designates the No.1 packet and then the readout of No.1 packet to a buffer BUF and stores the readout data at the memory of itself to confirm if it is addressed to itself or the No.1 packet and the data error is checked. If no error, the voice data of the packet is given to a terminal ADS and written in the data memory. When the processing of the No.1 packet is finished, the device PD takes the packet to No.2 after the incoming of a clock pulse CLP and the processing is repeated. Thus, if reception error takes place, the reception error packet is interpolated with the packet data immediately before at the reception side.
