If the RTP ports are incorrectly assigned, the following warning message is displayed:
Multicast settings for stream 1 / Multicast settings for stream 2: Select the Always multicast to
enable multicast for stream 1 or stream
2.
Unicast video transmission delivers a stream
through point-to-point transmission; multicast, on the other hand, sends a stream to the
multicast group address and allows multiple clients to acquire the stream by requesting a copy
from the Multicast group address.
The five ports can be changed between 1025 and
65535.
The multicast RTP port must be an
even number and the multicast RTCP port number is the multicast RTP port number plus one,
and thus it is always be odd. When the multicast RTP port changes, the multicast RTCP port
will change accordingly.
If the multicast RTP video ports are incorrectly assigned, the following warning message is
displayed:
Multicast TTL [1~255]:The multicast TTL (Time to live) is the value that tells the router the
range a packet can be forwarded.
The path of multicast stream1 is http://camera's IP address/live1.sdp while the one of multicast
stream2 is http://camera's IP address/live2.sdp.
