Nits/editorial comments: -[Page 3], Section 1.4, Suggestion for clarity: Old:"These metrics are used to report how the jitter buffer at the receiving end of RTP stream behaves as a result of jitter in the network and are applicable to a range of RTP applications." New:"These metrics are used to report how the jitter buffer at the receiving end of RTP stream behaves as a result of jitter in the network; and they are applicable to a range of RTP applications." -[Page 5], Section 3, paragraph 5, Suggestion for consistency: "The Jitter Buffer"---->"The jitter buffer" -[Page 5], last sentence, Suggestion for clarity: "Assume that both are normalized in ticks."-----> "Assume that both are normalized in ticks (there are 10 000 ticks in a millisecond). -[Page 6], point (iii), Suggestion for clarity: "If r = t" --suggestion--> "If r == t" -[Page 6], point (iv), Possible inconsistance: "Delay playout of packet by D + (r-t)" Comment: D is not normalized in ticks. r and t are. -[Page 7], Section 4.1, Suggestion for consistency: "JB Metrics Block"---->"Jitter Block (JB) Metrics Block" -[Page 8], 3 lines before last, "the time spend"--typo-->"the time spent" -[Page 9], line 9, missing "." before "In simple": "It is calculated based on the time spent in the jitter buffer for the earliest arriving packet In simple..." -[Page 16], Section 10.2 Reference [QMB] does not point to latest version.
