Site Assessment for Live Video Programming
Organizations that use Cisco Cast tend to show live video programming at their sites with the greatest
bandwidth capacity, such as their main site. Live video programming is not suitable for remote branch
offices with low bandwidth capacity.
When you plan how many TV channels to configure, consider the actual bandwidth capacity in your
WAN and at each remote site where you will use Cisco Cast. The typical rate of bandwidth consumption
will be in the range from 2 Mbps to 16 Mbps per channel, per site.

Channel Count Restrictions
Features of this Cisco Cast release support 99 or fewer channels of live broadcast programming and VoD
programming, combined.
Codec Restrictions
Any digital encoders that you use for live broadcast channels must adhere to the MPEG2-TS standard
for streaming and must support at least one of these codecs:
• MPEG1
• MPEG2
• MPEG4/h.264 (supported on DMP 4400G endpoints only)
For this reason, we recommend that you use a Scientific Atlanta 9032SD encoder or 9050HD encoder to
encode the video streams that your DMPs use for Cisco Cast channels.
