RFC 2354 on Options for Repair of Streaming Media

Our internet-draft on Options for Repair of Streaming Media has been published by the IETF as RFC 2354.

A number of applications have emerged which use RTP/UDP transport to deliver continuous media streams. Due to the unreliable nature of UDP packet delivery, the quality of the received stream will be adversely affected by packet loss. A number of techniques exist by which the effects of packet loss may be repaired, including redundant audio encodings, retransmission, interleaving and forward error correction. These techniques have a wide range of applicability and require varying degrees of protocol support. In this document, a number of such techniques are discussed, and recommendations for their applicability made.
