Using Multicast
About Multicast
Multicast is a one-way communication service that allows one HD Visual Communication Unit to multicast
video and audio to other multiple units, which receive the communication and show it.
The data received and shown by a unit can also be sent along to other units, as the receiving unit can function
as a relay terminal. Each unit can relay data to 2 other units, and in a configuration with 5 layers of relays, a
system of 31 units can be established.
A multicast system is composed of the following terminals.
•
Multicast terminal: The top-level terminal that multicasts video and audio
•
Relay terminal: Receives video and audio from a higher-level terminal and relays it to a lower-lever terminal.
(The received contents are also shown at the relay terminal.)
•
Receiver terminal: Receives video and audio.
