Abstract: An encoding system includes a plurality of encoders each of which encodes a signal having continuity supplied from a corresponding one of a plurality of information sources and generates a packet containing a portion of the encoded signal. Each encoder is classified as a first encoder which encodes the signal, or a second encoder which transfers the packet from at least one of the first encoders, to a communication network and which, when the first encoder has failed, replaces the failed first encoder. When a failure occurs in either one of the first and second encoders for any of the signals, the other one of the encoders detects the occurrence of the failure, reallocates the encoders other than the failed encoder so as to act as the first encoder or second encoder for respective ones of the information sources, and notifies each encoder of the result of the reallocation.
