Multicast audio port MPEG-4:
In MPEG-4 format, the streams for video and audio are transmitted
over separate ports. If you want to transmit MPEG-4 with audio you
must assign a dedicated audio port.
Enter here the port address for the MPEG-4 audio stream.
Note
For MPEG-4 audio transmission the option MPEG-4 audio G.711
in the MPEG-4 Encoder settings must be activated (see page 51).
Multicast packet TTL:
By setting the parameter you determine the life span of the data
packets in the network. If multicast is operated over a router the
value must be greater than 1 to guarantee transmission of the
packets.
