Codec
H.264
This is a video compression standard that makes good use of bandwidth and
could provide high-quality video streams.
The H.264 standard provides the scope for a large range of different coding tools
for use by various applications in different situations, and the GANZ PixelPro
provides certain subsets of these tools.
Using H.264, it is also possible to control the bit rate, which in turn allows the
amount of bandwidth usage to be controlled. CBR (Constant Bit Rate) is used to
achieve a specific bit rate by varying the quality of the H.264 stream. While using
VBR (Variable Bit Rate), the quality of the video stream is kept as constant as
possible, at the cost of a varying bit rate.
Motion JPEG
This format uses standard JPEG still images in the video stream. These images
then are displayed and updated at a rate sufficient to create a stream that shows
constantly updated motion.
The Motion JPEG stream uses considerable amounts of bandwidth, but also
provides excellent image quality and access to every individual image contained
in the stream. Multiple clients accessing Motion JPEG streams could use
different image settings.

Bit-rate control (CBR or VBR)
When using H.264 compression, if there is only limited bandwidth available, a
constant bit rate (CBR) is recommended, although this may compromise image
quality. Use a variable bit rate (VBR) for the best possibly image quality.
Average Bit-rate (512Kbps ~ 10Mbps)
Recommended bit rate for D1 or VGA : 800Kbps ~ 1Mbps
Recommended bit rate for 1.3M (720p) : 3Mbps ~ 4Mbps
Recommended bit rate for 2.0M (1080p) : 6Mbps ~ 8Mbps
