(Scalable
Video
Coding)
is
a
video
compression
algorithm
that
enables
effective
and

transmission
of
video
files
over
low
bandwidth
networks.
CBR -
To guarantee the designated constant bit rate, the quality of video are controlled in this mode.
Therefore,
the
quality
of
video
is
likely
to
be
varying
when
network
traffic
is
changing.
VBR -
To guarantee the designated quality, the bit rate of video stream is changed in this mode.
Therefore,
the
frame
rate
of
video
is
likely
to
be
varying
when
network
traffic
is
changing.
