Re: [payload] WGLC on draft-ietf-payload-melpe-02

Hi,

I reviewed the document and have some comments

 

1.       In the abstract you can delete the last sentence "Also, within the
document there are included necessary details for the use of MELP with SDP."


2.       I assume that sections 3.1.1, 3.1.2, 3.1.3, 3.2 are copied from
STANAG 4591 in which case you can just provide a reference to the relevant
sections

3.       In section 3.3 it looks like a MELPE packet can be of zero coded
frame and zero comfort noise frame?

4.       For section 3.4 look at RFC7587 section 5 for text suggestions

5.       In section 4.1 the type name is audio while the subtype names are
MELP,.

6.       In section 4.1 published specification "RFCXXXX" to be replaced by
the RFC Editor

7.       In section 4.2 we do not use MIME but "media type" (audio) and
"media subtype " (MELPE,.)

8.       The following text is not clear "A remote MELPe encoder SHALL
receive "bitrate" parameter in the SDP "a=fmtp" attribute by copying them
directly from the MIME media type string as a semicolon separated with
parameter=value, where parameter is "bitrate", and value can be one or more
of 2400, 1200, and 600 separated by commas (where each bit-rate value
indicates the corresponding MELPe coder). Is this for the an offer?

9.       We use "For declarative SDP" and not "For streaming media". It also
better to have a sub section for SDP offer answer considerations and
Declarative SDP considerations

10.   In section 8 "its media decoder" use "the MELPe encoder"

Hi,

I would like to start a WGLC on

Format for MELPe Codec
 
 
 

The WGLC will end on August 9th , 2016

 

Please review the draft and send comments to the list.

 

For the draft authors;  Are you aware of any IPR that applies to
draft-ietf-payload-melpe-02? 

If so, has this IPR been disclosed in compliance with IETF IPR rules?

The above question is needed for the document write-up when sent to
