Setup Information (Cont.)
channels will be 95, 96, and 97. Refer to EIA-542 STD CATV frequency allocation tables
for further information as required.
The highest available RF channel number for the OAT100R is 135. Thus, to allocate all
four channels available for OAT100R RF output, the RF start channel must be set no
higher than 132.
__ Find a location on the frequency spectrum that is free of existing noise.
Channel Assignments for IP Output
__ The OAT100R outputs IPv4 multicast streams. Ensure the institution’s IP network and
room receivers support IPv4 multicast and that the network is capable of selectively routing
multicast traffic. Refer to vendor equipment documentation for further information.
__ Create a channel assignment plan for the installation site, or modify an existing plan to
incorporate the IP output of the OAT100R. Ensure that up to eight unused and unreserved
IPv4 multicast addresses, within the designated range 224.0.0.0 to 239.255.255.255, are
allocated for the OAT100R IP output.
IP channels are user-assigned during system setup. You may opt to specify an IP start
channel and enable the system to auto-increment the remaining channel assignments. For
example, if the IP start channel assignment is 227.0.0.40, the remaining channels will be
227.0.0.41, 227.0.0.42, etc. Or, you may opt to manually specify the IP details for each IP
channel.
__ Reserve at least one User Datagram Protocol (UDP) port for the multicast data streams.
You can use the system default (1234) or another unassigned port number for each data
stream, as required, for example, 50000, 50001, etc. The port(s) must avoid conflict with
other protocols in use.
Note:
Refer to the IANA IPv4 Multicast Address Space Registry and/or the IANA Service
Name and Transport Protocol Port Number Registry for further IP address/port information as
required.
Packet Identifiers (PIDs)
Note:
If Pro:Idiom channels are NOT present in the site’s entertainment system, PIDs do not
need to be set in the OAT100R, and therefore, you will not need to design a PID map for the
OAT100R output.
Note:
See also “Packet Identifiers (PIDs) Overview” on the following page.
__ Survey the PIDs currently used in the system, and design a PID map for the OAT100R
output (ensure that up to 64 PIDs are allocated). Ensure that Pro:Idiom message PIDs are
never used by the video/audio PIDs for the OAT100R channels (or any other system
elements).
The program start PID is user-assigned during system setup, and the 63 remaining PIDs
are then automatically assigned within the 64-PID contiguous block.
__ PIDs must be specified in the OAT100R system as hexadecimal numbers.
