RTP (Multicast) Settings
When switching to providing multicast content on the network, there will be no difference in the video stream when compared to ordinary unicasting. The web page containing the content from the AXIS 230 will function exactly as before, and viewers will not experience any change.
To provide multicast broadcasts to multiple viewers, various settings may need to be made. Most importantly, the box “Enable multicast” must be checked.
The other multicast settings concern the IP addresses and port numbers to use for the audio and video streams. If the IP addresses for the two streams are the same, then the ports must be different. Inversely, when using different IP addresses, then the ports can be identical.
Note that viewers do not need to know these IP addresses.
The IP addresses used for muticasting audio and video streams should always be selected from within certain specific ranges. The AXIS 230 has been
The final multicast setting is the Time to live value. If IP packets (i.e data) fail to get delivered to their destination within a reasonable length of time (which could be for various reasons), this setting tells network routers when to discard the packet. The value is usually measured in "hops", i.e. the number of network routers that can be passed before the packet arrives at its destination or is dropped.
Important!
Note that some network routers may need to be configured to allow RTP traffic.
