3.13.2 Streaming
Streaming lets you broadcast your meeting to participants on web. The web participants can
listen to the meeting, see snapshots, but not participate themselves. Snapshots of current
stream (if MultiSite), selfview, far end and DuoVideo streams are accessible via http. See
Appendix 7 for descriptions of the possible snapshot files.
How to use Streaming:
1. Choose Streaming from the Control Panel to open the Streaming menu.
2. Press Start Streaming from the menu line.
3. Press Stop Streaming to end streaming. Streaming will also end when you disconnect
the call.
4. Press Streaming Settings if you want to change streaming settings (see Streaming
Settings below)
How to view streaming from a PC:
1. After streaming is started, an easy way to view the streamed audio/video is to start
your Web browser and enter the IP-address of the streaming system.
2. After the Web page of the system is shown, click on Streaming. Alternatively, enter
http://<codec ip-address>/stream.sdp
Streaming Settings
Address
Address is defined as the IP-address of a streaming client,
streaming server or a multicast address. Giving an address in the
range 224.0.0.1-239.255.255.255 will broadcast the stream to any
host that has joined the specified multicast group. Specifying normal
broadcast address 255.255.255.255 will broadcast to any members
on the LAN.
Address Port
If several codec’s are streaming to the same IP-address, different
ports have to be used in order for the client to know which stream to
receive. If the first codec streams on port 2240 and the second
codec on port 2250, the client has to specify which port to listen to.
Video is transmitted on the specified port; audio is transmitted on the
port number 4 above the specified video port, in this case 2244 and
2254.
TTL/Router
Hops
This is used for streaming data to limit how many routers the data
should pass before it is rejected. If TTL is set to 2, data will not
traverse more than 2 router hops.
