+Abstract
+
+   The RTP (Real-time Transport Protocol) payload format for generic
+   forward error correction allows RTP participants to improve loss
+   resiliency through the use of traditional parity-based channel codes.
+   This payload format requires four new MIME types, audio/parityfec,
+   video/parityfec, text/parityfec and application/parityfec.  This
+   document serves as the MIME type registration for those formats.
+
+1 Introduction
+
+   The RTP payload format for generic forward error correction [1]
+   allows RTP participants to improve loss resiliency through the use of
+   traditional parity-based channel codes.  This payload format requires
+   four new MIME types, audio/parityfec, video/parityfec,
+   text/paritfyfec and application/parityfec.  RFC 2048 [2] defines
+   procedures for registration of new MIME types within the IETF tree.
+   Furthermore, the Audio/Video Transport working group has defined
+   additional procedures that must be followed when registering RTP
+   payload formats [3].  This document serves as the MIME type
+   registration for those formats based on those procedures.

+2 Registration of audio/parityfec
+
+       To: ietf-types@iana.org
+
+       Subject: Registration of MIME media type audio/parityfec
+
+       MIME media type name: audio
+
+       MIME subtype name: parityfec
+
+       Required parameters: none
+
+            Note that [3] mandates that RTP payload formats without a
+            defined rate must define a rate parameter as part of their
+            MIME registration.  The payload format for generic forward
+            error correction [1] does not specify a rate parameter.
+            However, the rate for FEC data is equal to the rate of the
+            media data it protects.
+
+       Optional parameters: none
+
+            Typical optional parameters [3], such as the number of
+            channels, and the duration of audio per packet, do not
+            apply to FEC data.  The number of channels is effectively
+            the same as the media data it protects; the same is true
+            for the duration of audio per packet.
+
+       Encoding considerations: This format is only defined for
+            transport within the Real Time Transport protocol (RTP)
+            [4,5].  Its transport within RTP is fully specified with RFC
+            2733 [1].
+
+       Security considerations: the same security considerations
+            apply to these mime registrations as to the payloads for
+            for them, as detailed in RFC 2733.
+
+       Interoperability considerations: none
+
+       Published specification: This MIME type is described fully
+            within RFC 2733 [1].
+
+       Applications which use this media type: Audio and video
+            streaming tools which seek to improve resiliency to loss by
+            sending additional data with the media stream.
+
+       Additional information: none
