              Forward-Shifted RTP Redundancy Payload Support


   This document defines a simple enhancement to support RTP sessions    with forward-shifted redundant encodings, i.e., redundant data sent    before the corresponding primary data.  Forward-shifted redundancy    can be used to conceal losses of a large number of consecutive media    frames (e.g., consecutive loss of seconds or even tens of seconds of    media).
