Archives and Live Streaming

While operations in this section are basically the same for administrators and

ordinary users, the difference lies in their rights. The administrator can view

and modify all recorded files currently archived by the system and live

streamed video through the Web UI, and delete archives. Ordinary users can

only view and modify recorded files and live streaming videos on which

they are authorized to perform such operations. For description of Archive

page, see Archives. For description of Live Streaming page, see Live Streaming.

Live Streaming Resources Usage

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 Defining a Template. The following table shows the

relationship between those aspects and the amount of resources that are

used.
