Subscribing to a Stream
To receive information from an encoder, the decoder must
subscribe
to the multicast IP address and UDP port of
the stream(s). Note that the decoder does not subscribe to the session, but to the stream(s) within the session.
The process of subscribing is similar to changing the channel on a Set-Top Box. For example, in order to view the
content on channel 213, the Set-Top Box must be set to channel 213. Similarly, for a decoder to subscribe to an
encoder stream,
the multicast IP address and UDP port settings on the decoder must be set to the same values as
the encoder to which it is subscribed.
Note that the management IP address of a unit is different than its multicast IP
address.
Figure 1.3
shows two encoders and a single decoder connected to a network switch. Decoder “C” is subscribed to
encoder “A”, since the multicast IP addresses and UDP port numbers for both video and audio are set to the same
values as encoder “A”.
