Mulcast stream (send) or decode one (receive).

All Mulcast connecons are outgoing connecons. A Mulcast Sender must iniate an outgoing stream, and a Mulcast
Receiver must iniate an incoming one. These remotes are congured within a special address range known as a
Mulcast Block, typically 224.0.0.0 to 239.255.255.255. To establish a Mulcast connecon, simply dene a remote as
having an address within the IP Mulcast Block, use an IP Mulcast prole, and press.

Time-to-Live (TTL) is a variable set by Mulcast encoders to determine how long a packet is processed before it is
dropped by the network. The default value of TTL in ACCESS is 0, which limits its use to within a LAN environment. TTL
may be manually changed on a Mulcast Sender remote by conguring the IP address followed by a “/” (forward slash),
followed by the TTL value.
As an example, a remote Mulcast encoder could be set for the address , which would signify an address
with the Mulcast Block with a TTL of  (which is the max value available).

The default port of UDP 9000 may also be changed on Mulcast remotes. The port number is assigned in the usual way,
directly aer the IP address, preceded by “:”, followed by the TTL. As an example, the IP address of a Mulcast Sender on
port 443 with a TTL of 100 would read:
