How To Distribute Live Video using IP Multicast
IP Multicast is a one-to-many routing technology supported by sophisticated
networks. It is not well supported by most WiFi implementations, and DEVOS uses
conventional unicast for the reliable delivery of video.
For sophisticated networks and where a very large live viewing audience is needed
(e.g. 20,000+ live viewers), DEVOS supports IP Multicast very easily. Simply follow
these steps.
Navigate to Advanced Options and select Push Stream
For the Push Destination, enter: mpegtsudp://[multicast IP]:[port]. For
example to send video to multicast address 239.1.2.3 on port 4444, enter
mpegtsudp://239.1.2.3:4444
Leave the Push Stream Name blank
For the Stream, select the live stream you wish to use
Select Create Push
Whenever the live stream from Streamsie or Mantis is available, it will now also be
sent via multicast to the selected address.
Discover Video offers a unique browser-capable multicast technology that does not
requires a brower plug-in but does require a simple user install. Contact Discover
Video for more information.
Note: sending a multicast on a network that is not configured to accept it can lead to
packet port flooding. At lower video streaming bit rates, this may be acceptable, but it is
not a desired behavior of a network. You may select any multicast address that is not
already in use, from 224.0.0.0 to 239.255.255.253
(see http://en.wikipedia.org/wiki/Multicast_address)
DO NOT USE MULTICAST FOR DEVOS CLOUD OR FOR INTERNET
