About the VMC 1000
The VMC 1000 manages live and video-on-demand (VOD) content created by
Polycom RSS 2000 devices and manages video streams (in Windows Media
format) created by other devices and uploaded to the VMC 1000. It provides
scalable and reliable content access by means of streaming protocols to end
users across the entire enterprise.
The VMC 1000 discovers new live and archived video calls recorded by RSS
2000 devices by periodically polling all registered RSS 2000 servers for a list of
live and archived calls. After each request, the 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 VMC 1000 uses this information to create assets (Resource Bin items) and
published events (Programs) to be accessed by end users (Content Owners,
Site Administrators, and Viewers). The 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 2000 is discovered, it is connected to an entry
point (publishing point) on a standard Windows Media Server 9.
