VBR (Variable Bit Rate) video aims at
constant quality, but as the bit rate
uctuates over time.
CBR (Constant Bit Rate) video
uctuates in quality, while its multi-
plexing behaviour is easy to predict.
Because in unconstrained VBR video
the bit rate uctuation might be too
large, capped VBR video is proposed
as an alternative. Capped VBR video
aims at a constant quality, but when in
certain intervals this requires a too
high bit rate, the bit rate is limited
(i.e.,capped) in order to support more
video ows on the links, at the
expense of a quality reduction.

system” from page 60 for more details.
Note! Only even port numbers can
be used for RTP, and then the
following odd port number shall be
used for RTCP (RFC 1889).
