Live Streaming Resources Usage

The number of resources supported by the Polycom RSS 4000 system for live
streaming the video depends on the system model you purchased. The
following table shows the relationship between the model and the resources it
supports.
Model Resources Required
Small 5 4
Medium 10 6
Large 15 8
The combination of frame rate, resolution, number of rates used and video
layout affects the number of resources required on the Polycom RSS 4000
system to support live streaming. For information about setting the rates and
the video layout, see
relationship between those aspects and the amount of resources that are used.

Referring to the above table, you can easy calculate the number of live streams
supported by the system in concrete scenarios.
Taken a Small model system that supports four resources as the example. If
there is an ongoing live streaming sending video at 720p 30 fps and recording
video at 1080p 30 fps/1080p 60 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.
