About the Polycom VMC 1000
The Polycom VMC 1000 manages live and video-on-demand (VOD) content
created by Polycom RSS devices and manages video streams created by other
devices and uploaded to the Polycom VMC 1000. It provides scalable and
reliable content access by means of streaming protocols to end users across the
entire enterprise.
The Polycom VMC 1000 discovers new live and archived video calls recorded
by RSS devices by periodically polling all registered servers for a list of live
and archived calls. After each request, the Polycom VMC 1000 compares the
current list with a list obtained by the previous request and discovers the
difference between the two states (i.e. which live conferences and recorded
files were added).
The Polycom VMC 1000 uses this information to create assets (Content
Repository items) and published events (Programs) to be accessed by end
users (Content Owners, Site Administrators, and Viewers). The Polycom VMC
1000 uses different time frames to query for live and recorded content - for
example, it could query every 10 seconds for new live streams and every 60
seconds for new recorded files.
Once a live stream from the RSS device is discovered, it is connected to an
entry point (publishing point) on a standard Windows Media Server 9.
The Polycom VMC 1000 only requires a single stream to be pulled from a
recording and streaming server to enable hundreds of streams. The Polycom
VMC 1000 publishes live event links on its Viewer Portal and redirects end
users to the live streams from a streaming server.
