Address
Address is defined as the I P -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 broadca st the stre am to any host that has joined
the specified multicast group. Specifying norm al broadcast address
255.255.255.255 will broadca st to any membe rs o n the LAN.
Address Port
If several cod e c’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 greater than the specified vide o 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.
