Tick the box to enable ‘multicast’. If the box is not ticked then ‘unicast’ is selected.
• Multicast Stream 1 - Set IP address and port for stream 1.
• Multicast Stream 2 - Set IP address and port for stream 2.
(See Video - Stream Type - page 47).
RTSP protocols allow ‘multicast’ or ‘unicast’ transmission. In addition to the ‘multicast’ feature being available on
the Predator-HD, the ‘multicast’ feature must also be available on the receiving device.
Unicast
If lots of receivers (users) want to receive video streams from the Predator-HD, each receiver will have a
separate video stream. This would increase the network bandwidth used. E.g. five users would require five
video streams, that typically will require five times the bandwidth.
Multicast
If the receivers of the video streams are suitable for using ‘multicast’ and the video streams will all have the
same format, then it may be possible to use ‘multicast’. In this mode, the CODEC in the Predator-HD chooses
a ‘new UDP address’ (Typically an address which is outside the normal range of addresses for the network to
which the Predator-HD is connected) and sends a video stream to the ‘new UDP address’. Multiple receivers
can then access this single video stream. Consequently the bandwidth that is required by the Predator-HD is
typically reduced to the single video stream.
When using ‘multicast’ all intermediate network-switches and routers must be set to allow the stream from the
‘new UDP address’ to be routed correctly.
