Summary: Ready with nits, primarily a number of acronyms needing expansion.

Major issues:
None

Minor issues:
None

Nits/editorial comments:
Abstract: Need to expand RTCP (to RTP Control Protocol) and XR (Extended 
Reports).

s1, para 2: Need to expand QoE.

s1.2: s/RTP Monitoring Architectures [RFC6792]/RTP Monitoring Framework 
[RFC6792]/

s1.3:
OLD
    These metrics are applicable to video applications 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.
NEW:
    These metrics are applicable to video applications and the video
    component of Audio/Video applications using RTP that apply packet
    loss concealment mechanisms incorporated into the receiving
    endpoint to mitigate the impact of network impairments on QoE.
END

s1.3: Need to expand IPTV.

s3, item b: Need to expand IDR;
                    s/Using inter-frame extrapolation/Using the 
inter-frame extrapolation/

s3, item d: s/so that receiver/so that the receiver/

s3, last para: s/methods slightly different/methods to be slightly 
different/

s4, para 1: Need to expand SSRC.

s4, duration fields:  It would useful to insert a reference to the place 
where the RTP timestamp units are defined.

s7.1: should refer back to s4 for the definition of VLC.

s7.2: should refer back to s5 for the definition of video-loss-concealment.
