<p><P>PROBLEM TO BE SOLVED: To make the missing data hardly affecting and limit the delay to to a minimum limit in a real time data communication. <P>SOLUTION: A data telecommunication system transmits the data encoded by a plurality of coding means at a transmission side, receives the encoded data of a plurality of channels sent from the transmission side by corresponding decoding means at a reception side. The data telecommunication system checks whether there is the decoding process of a frame F3 in which a packet is lost or not when the decoding means 401 for processing to decode at present, for example, detects a packet loss ("x" mark) in the frame F3, searches for the decoding means (decoding means 402 in Fig.) which can process to decode, or dynamically switches the decoding means which can suitably decode the frame when the packet loss is detected by the decoding means which processes to decode at present so as to select the decoded data of the decoding means 402, and selects the suitable decoded data. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
