A method for providing packet loss recovery in a data packet-based network used for real-time multimedia communications. In accordance with a first illustrative embodiment of the present invention, the information payload associated with a given data packet k is identically copied and appended to data packet k+w (i. e., the information payload is repeated with a delay of w transmitted packets). More generally, the present invention provides a method of coding a sequence of data packets representin g a continuous stream of information, each data packet comprising a set of paylo ad information representative of a segment of the stream of information corresponding thereto, the method comprising the steps of coding a first data packet for transmission, wherein the encoded first data packet comprises a first set of payload information representativ e of a first segment of the stream of information; and coding a second data packet subsequent to the first data packet in the sequence for transmission, wherein the encoded cond data packet comprises a second set of payload information representative of a second segment of the stream of information subsequent to the first segment of the stream of information, and wherein the encoded second data packet further comprises an additional set o f payload information, the additional set of payload information also representative o f the first segment of the stream of information, but not representative of other segmen ts of the stream of information.
