Multicast IP Address
Multicasting helps to broadcast audio and video data from a transmitter to
multiple Receivers over a network. To setup up Multicasting on a network
switch you must know the Audio and Video Multicast IP address which can be
found on the KE Transmitter. To determinate the default Multicast IP address
set by the KE device use the instructions below. The Multicast IP addresses can
be set manually using Telnet.
KE Multicast Rule
All Audio and Video Multicast IP addresses use the format: 230.X.Y.Z.
X.Y.Z relates to the Transmitter’s IP address and 230 is always the first octet
of a Multicast IP address. You use the Transmitter’s IP address to find X and
then use it to calculate the Audio and Video Multicast IP address.
Multicast IP Formula
To calculate the Audio and Video Multicast IP address, use the Transmitter’s
IP address to determine X and then use the appropriate table below to calculate
the Multicast IP address for each data stream (audio/video).
Example:
Transmitter IP Address: 172.16.27.146; (172.X.Y.Z)
X =16
If X is between 0 ~ 127
Transmitter IP X
Video
X + 128
Audio
X + 192

(example)
16 16 + 128 =
144
16 + 192 =
208
230.144.27.146 230.208.27.146
___+ 128 = ___+ 192 =
230.___.___.__ 230.___.___.__
___+ 128 = ___+ 192 =
230.___.___.__ 230.___.___.__
___+ 128 = ___+ 192 =
230.___.___.__ 230.___.___.__
