Referring to the above table, you can easy calculate the number of live
streams supported by the system in concrete scenarios. Take a Small model
system that supports four resources. If there is an ongoing live streaming
sending video at 720p 30 fps and recording video at 1080p 30 fps/720p 60 fps,
using two rates and single window layout, it occupies three resources on the
system. Then there is one resource free, which allows for running one live
stream at CIF/4CIF/720p 30 fps, using a single rate and single window
layout concurrently.
The following table shows the maximum capacity of the Polycom® RSS™
4000 systems when perform the live streaming of different parameters:
