Hi，

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

1. Section 1.4
Editor Notes needed to be cleared.
 
2. Section 2.1 Report Block Structure
s/Loss Concealment metrics block/Concealed Seconds metrics block
 
3. Section 2.1 figure 1
s/BT =NLC/ BT =NCS
 
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.
"
 
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.
 
 
Claire
