Multicast audio port:
With MPEG-4, video and audio data is transmitted via separate ports. To transmit MPEG-4 with audio you must
assign a dedicated audio port.
Note
Audio data is only transmitted if the corresponding function on the Audio configuration page is enabled
(see page 24).
Multicast packet TTL:
This value determines the "life span" of multicast packets on the network. If multicast is operated via a router,
the value must be greater than 1 to ensure that the packets are passed on.
