Lecture Mode
Scopia Desktop's lecture mode allows the participant defined as the lecturer to see all the participants,
while they see only the lecturer. All participants are muted except the lecturer, unless a participant asks
permission to speak and is unmuted by the lecturer. This mode is tailored for distance learning, but you
can also use it for other purposes like when an executive addresses employees during company-wide
gatherings.
Load balancer
A load balancer groups together a set (or cluster) of servers to give them a single IP address, known as
a virtual IP address. It distributes client service requests amongst a group of servers. It distributes loads
according to different criteria such as bandwidth, CPU usage, or cyclic (round robin). Load balancers are
also known as application delivery controllers (ADC).
Location
A location is a physical space (building) or a network (subnet) where video devices can share a single
set of addresses. A distributed deployment places these components in different locations, often
connected via a VPN.
Management
Management refers to the administration messages sent between components of the Scopia Solution as
they manage and synchronize data between them. Management also includes front-end web browsers
interfaces sending server settings to the back-end server.
MCU
An MCU, or Multipoint Control Unit, connects multiple endpoints into a single videoconference. It
typically manages the audio mixing and video layouts, adjusting the output to suit each endpoint's
capabilities.
MCU service
Media
Media refers to the audio, video and data real time streams sent during a call. Besides the live audio and
video streams, you can also send a shared data stream, like a presentation, also known as dual video.
Far end camera control (FECC) is another example of information carried on the data stream. Media is
transmitted via the RTP and RTCP protocols in both SIP and H.323 calls.
