Hi Zheng, See inline Roni From: Fang, Zheng [mailto:zfang@qualcomm.com] Sent: Tuesday, October 04, 2011 2:44 AM To: Roni Even; payload@ietf.org Cc: Wang, Min; Sinder, Dan; Huang, Pengjun (Jeff); Kandhadai, Ananthapadmanabhan (Ananth); Fang, Zheng Subject: RE: [payload] WGLC on draft-ietf-avt-rtp-evrc-nw-03 Hi Roni, Thank you for your comments and suggestions. I updated the draft based on your suggestions. Please find attached the modified text and diff. I am not sure how to address some of the comments. My answers to those questions are in line. I would appreciate it if you could further comment on it. I will submit a new version once I resolve all the comments. Thanks! Zheng From: Roni Even [mailto:Even.roni@huawei.com] Sent: Monday, August 29, 2011 4:35 AM To: payload@ietf.org Cc: Fang, Zheng Subject: RE: [payload] WGLC on draft-ietf-avt-rtp-evrc-nw-03 Hi, I reviewed the draft and have some comments. 1. It looks to me that this draft updates RFC3558 similar to RFC 4788 and RFC 5188. It should be referenced in the header and in the text [Zheng] Although the payload definition of EVRCNW is similar to EVRCWB (RFC 5188), EVRCB (RFC 4788) and EVRC (RFC 3558), the current draft only defines the payload format for EVRCNW only. This is different than that of RFC 5188, which not only defines a new MIME type (EVRC-WB) but also update an existing MIME type (EVRC-B in RFC 4788). [roni] OK 2. In section 6 first paragraph why not reference 3788 where ToC is defined. [Zheng] Reference is added. 3. In second 9 in the registration template you have sendmode deprecated. This is strange since this registration is a new registration so there is nothing to deprecate . If you want to state that this optional parameter that is used in other EVRC modes is not used, please do it in another section and not in the registration section. [Zheng] The sendmode descriptions are removed from the registration templates. Instead a comment on it is added in Section 10 "SDP mode attributes for EVRC-NW". 4. In section 9 in the published specification you mention RFC3558 without a reference. I think that this document need also to be specified since it defines the RTP header and the usage. [Zheng] References are added. 5. In section 9 in the author field add your email address [Zheng] Done. 6. In section 9 change controller should be " IETF Audio/Video Transport working group delegated from the IESG." [Zheng] I am a little confused. The changed controller was indeed the same as you mentioned. Can you please point it out in case I miss anything? [roni} my mistake should be "IETF Payload working group delegated from the IESG" 7. In section 13 how is "mode-set-recv" used in declarative SDP since it is a decoder capability and not an encoder one. [Zheng] In some two-way conversation scenarios, the traffics can be asymmetric, i.e, incoming and outgoing streams use different sets of modes. It is sufficient to declare decoder capability and the encoder at the other side simply follows. [roni] Declarative is a one way announcement like in SAP for streaming media, so there is no encoder at the other side.
