Subject: [xrblock] Comments on draft-ietf-xrblock-rtcp-xr-concsec

Hi，

Several quick comments to draft-ietf-xrblock-rtcp-xr-concsec:

1. Section 1.4
Editor Notes needed to be cleared.
 
[Qin]: To clear the Editor Note, we need firstly reach agreement that
this draft should also need to support packet loss concealment for video application.
 
[Claire]:OK. I have another question. Once this agreement is reached, is this metric still primarily for audio applications of RTP? If not, the abstract, section 1.1 and other related sections should also be upgraded. Maybe this also needs to be discussed in Atlanta.
2. Section 2.1 Report Block Structure
s/Loss Concealment metrics block/Concealed Seconds metrics block
 
[Qin]: Good catch, thanks.
 
3. Section 2.1 figure 1
s/BT =NLC/ BT =NCS
 
[Qin]: Okay.
4. Section 2.2 Unimpaired Seconds
There's no definition of VAD. I proposed we should add it in the text.
OLD TEXT：
"
...if VAD is used, shall be counted as unimpaired seconds.
"
NEW TEXT:
"
...if Voice Activity Detection (VAD) is used, shall be counted as unimpaired seconds.
"
[Qin]: How about not expand VAD, instead put a external reference to VAD which
explain what VAD is?
[Claire]:OK.
5. Section 2.2
"Packet Loss Concealment Method (plc): 2 bits"
If video loss concealment techniques are suppoted, 2 bit packet loss conealment method is not
sufficient.
 
[Qin]: Agree,probably we need to support addtional 4 or more video loss concealment method.
In that case, at least 4 bits is required.
[Claire]:Good sugestion. It makes sense to me.
 
Claire
