This draft was submitted for the 60th IETF meeting, and was not intended to be published as an RFC.

This memo describes how the RTP Payload Format for Generic Forward Error Correction can be combined with the Extended RTP Profile for RTCP-based Feedback to provide a solution for retransmission of lost RTP packets. Such a retransmission format is expected to be useful to improve the reliability of real-time applications with relaxed delay bounds, for example non-interactive streaming audio/video.
