Dear experts,
draft-ietf-fecframe-rtp-raptor-06 is currently in IESG review.
Please review its media type registration as provided below:
===================================================================
6. Media Types
6.1. Registration of the application/raptorfec media type
This RTP payload format is identified using the application/raptorfec
media type which is registered in accordance with [RFC4855] and using
the template of [RFC4288].
6.1.1. Media Type Definition
Type name: application
Subtype name: raptorfec
Required parameters:
o rate: The RTP timestamp (clock) rate. The operator SHALL select a
rate larger than 1000 Hz to provide sufficient resolution to RTCP
operations and the operator SHOULD select the rate that matches
the rate of the protected source RTP stream. The RTP timestamp
(clock) rate is specified in Hz and the format is unsigned
integer.
o raptor-scheme-id: The value of this parameter is the FEC Scheme Id
for the specific Raptor FEC Scheme that will be used as defined in
[I-D.ietf-fecframe-raptor].
o Kmax: The value of this parameter is the FEC Framework
Configuration Information element "Maximum Source Block Length" as
defined in [I-D.ietf-fecframe-raptor] encoded as a decimal
integer. For specific requirements for this value refer to
[I-D.ietf-fecframe-raptor].
o T: The value of this parameter is the FEC Framework Configuration
Information element "Encoding Symbol Size" as defined in
[I-D.ietf-fecframe-raptor] encoded as a decimal integer. For
specific requirements for this value refer to
[I-D.ietf-fecframe-raptor].
o repair-window: The maximum time that spans the source packets and
the corresponding repair packets. The size of the repair window
is specified in microseconds and the format is unsigned integer.
Optional parameters:
o P: The value of this parameter is the FEC Framework Configuration
Information element "Payload ID Format" as defined in
[I-D.ietf-fecframe-raptor]. If this parameter is missing the
value "A" SHALL be assumed.
Encoding considerations: This media type is framed and binary, see
section 4.8 in [RFC4288]
Security considerations: Please see security consideration in
[RFC6363]
Interoperability considerations:
Published specification: [I-D.ietf-fecframe-raptor]
Applications that use this media type: Real-time multimedia
applications like video streaming, audio streaming, and video
conferencing.
Additional information:
Magic number(s): <none defined>
File extension(s): <none defined>
Macintosh file type code(s): <none defined>
Person & email address to contact for further information: Thomas
Stockhammer, stockhammer@nomor.de
Intended usage: COMMON
Restrictions on usage: This media type depends on RTP framing, and
hence is only defined for transfer via RTP [[RFC3550]]. Transport
within other framing protocols is not defined at this time.

Information element "Encoding Symbol Size" as defined in
[I-D.ietf-fecframe-raptor] encoded as a decimal integer. For
specific requirements for this value refer to
