Hi all,

I have read this draft. I think it's ready for publication after addressing following editorial issues:


1.        Section 1.3, "These metrics are applicable to video applications of RTP and the video component of Audio/Video applications in which packet loss concealment mechanisms are incorporated into the receiving endpoint to mitigate the impact of network impairments on QoE."  Could be changed to
        "These metrics are applicable to video applications and the video component of Audio/Video applications using RTP and applying packet loss concealment mechanisms which are incorporated into the receiving endpoint to mitigate the impact of network impairments on QoE."

2.       In the draft, sometimes "Metric Block" is used and sometime "Metrics block" used. I think it should be consistent.
3.       Section 4, the definition of V, "Each bit indicates one method type, as follow:" SHOULD be modified.
4.       Section 6, "An attacker may put incorrect information in the Video Loss Concealment reports, which will be affect the estimation of video loss concealment mechanisms performance and QoE of users." should be changed to "affect"
5.       Appendix b,c,d,e,f, "* Measurement Timing: See paragraph 2 of Section 4." should be paragraph 1

Cheers,
Wei
