This section illustrates how the IP Audio Interface can
be used. A data stream could be sent and receive by the
IP Audio Interface. Different methods could be defined
which depends on how the device is configured.
5.1
Unicast (point to point)
Unicast means: a
single
data stream to a
single
predefined receiver device (Partner) in a LAN or WAN.
A typical partner IP address: 192.168.100.50
5.2 Multiple
Unicast
Multiple Unicast means
multiple
data streams to
multiple
receiver devices (Partners) in a LAN or WAN.
Typical partner IP addresses: 192.168.100.50,
192.168.100.51, 192.168.100.52, ...
5.3 Broadcast
Broadcast means: a
single
data stream to
all
receiver
devices (Partners) in a LAN. A typical partner IP
address: 192.168.100.255
configured in the transmitter
as Partner address. Then all partners with addresses
starting with 192.168.100 receive this stream. Typically,
routers in a WAN do not support Broadcast mode.
5.4 Multicast
Multicast means: predefined receiver devices (Partners)
each receive a
single
data stream in a LAN or WAN.
Typical partner IP addresses between: 224.0.0.1 to
239.255.255.255.
5.5 Re-broadcast
Re-broadcast means: a local device receives a data
stream from a remote device and resends it to other
devices (Partners) in a LAN or WAN.
