The Prodys codec operating over IP (Prodys Proprietary
Protocols)
The operation of the Prodys IP Family codec over IP offers three operational
modes: UNICAST, MULTICAST and MULTIUNICAST
16
.
V.6.1
UNICAST communications
The term
UNICAST
is used in the networking world to refer to the connection to
a
single destination
. Unidirectional or bidirectional audio streaming is possible
with this mode.
UNICAST is the default mode and is available for any IP protocol, but for SAP.
Given is an example for Prodys Proprietary Protocol flow-control:
V.6.2
MULTICAST communication
The
MULTICAST
mode stands for point-to-multi-point communications. This is
one transmitter streams audio towards one or several receivers
In order to start a MULTICAST communication, the connection must be
requested from both ends (transmitter and receivers).
Any participant, the
transmitter of the audio stream and all the receivers of the stream must join to
the multicast group
. It does not matter which participants joins first. Of course
the actual audio stream will be not available for decoding before the transmitters
joins to the multicast group; up to the audio availability any receiver will just
keep the audio outputs muted.

MULTIUNICAST is available from version 5.2.1 onwards.
