Video infrastructure can be loosely termed as layers of network and applications that are needed to successfully 

create an end-to-

end video Cisco TelePresence session. Figure 5 shows a typical video infrastructure. Now let’s 

consider each of the layers: 

● 

Network: The network is the foundation of all the layers. You need a reliable and efficient network for any 

video calls to go through it. 

● 

Endpoints: Endpoints are the video devices such as the personal Cisco TelePresence System EX90, the 

Cisco TelePresence Movi (Movi) Camera, or maybe the Cisco TelePresence System 1300 Series Server 

that is used to actually send and receive live video. 

● 

Call controllers and processors: Endpoints register themselves at call controllers and processors. These 

applications (for example, Cisco Unified Communications Manager or Cisco TelePresence Video 

Communication Server [Cisco VCS]) stipulate how the endpoints should be making the calls and the quality 

associated with them. 

● 

Multipoint bridges and switches: We can think of these bridges and switches as multipoint video 

switches, which facilitate more than one endpoint to talk to each other in real time. 

● 

Call scheduling and calendaring: This application allows the video calls to be scheduled just like 

Microsoft Outlook meetings. They can be tied to an existing corporate Lightweight Directory Access 

Protocol (LDAP) or Microsoft Exchange server to make it easier to deploy.
