The following errata report has been submitted for RFC5760,
"RTP Control Protocol (RTCP) Extensions for Single-Source Multicast Sessions with Unicast Feedback".

You may review the report below and at:

--------------------------------------
Type: Technical
Reported by: Alfred Hoenes <[email-masked]>

Section: B.4, pg.63

Original Text
-------------
   Constant value
   Due to the size of the multiplicative factor field being 4 bits, the
|  maximum multiplicative value is 15.

|  The distribution type field of this packet would be value 1 since it
   represents loss data.

Corrected Text
--------------
   Constant value
   Due to the size of the multiplicative factor field being 4 bits, the
|  maximum multiplicative value is 2^15.

|  The sub-report block type field of this packet would be value 4
|  since it represents a loss data histogram.

Notes
-----
Rationale:
  Apparently evolution of SRBT design for the body of the RFC
  have been missed in the Appendix.
  Changes above serve to obtain consistent use of terms and
  appropriate values.

  For improved readability, related changes for pp. 64/65 are being
  reported in distinct Errata notes.
