The following errata report has been held for document update 
for RFC3611, "RTP Control Protocol Extended Reports (RTCP XR)".

Status: Held for Document Update
Type: Editorial

Reported by: Tong Zhou <[e-mail]>
Date Reported: 2015-06-03
Held by: Ben Campbell (IESG)

Section: 4.7.2

Original Text
-------------
   For example, a 1 denotes a received packet, 0 a lost packet, and X a
   discarded packet in the following pattern covering 64 packets:

      11110111111111111111111X111X1011110111111111111111111X111111111
      |---------gap----------|--burst---|------------gap------------|

   The burst consists of the twelve packets indicated above, starting at
   a discarded packet and ending at a lost packet.  The first gap starts
   at the beginning of the session and the second gap ends at the time
   of the report.

   If the packet spacing is 10 ms and the Gmin value is the recommended
   value of 16, the burst duration is 120 ms, the burst density 0.33,
   the gap duration 230 ms + 290 ms = 520 ms, and the gap density 0.04.

   at the beginning of the session and the second gap ends at the time
   of the report.

   If the packet spacing is 10 ms and the Gmin value is the recommended
   value of 16, the burst duration is 120 ms, the burst density 0.33,
   the gap duration 230 ms + 290 ms = 520 ms, and the gap density 0.04.

Notes
-----
The pattern in the example shows 63 packets rather than 64. Added a "1" at the end. Another option is to keep the pattern unchanged, and redo the math.
