摘要： A method and devices using that method are provided for reconstructing an encoded signal conveyed along a communication path in a packet switched network. The method comprises the steps of providing a communication signal that has been encoded into a plurality of frames; determining which of the plurality of frames is an essential frame, which loss would cause a relatively substantial deterioration in the quality of at least one proceeding frame upon decoding that at least one proceeding frame; packaging the plurality of frames into a plurality of packets, and identifying which of the packets comprise at least one essential frame; adding protecting information to at least one packet which proceeds a packet identified as a packet carrying at least one essential frame.
