Video Channel Assignments for RF Output (DVB-C) with Solid State Drive
Each input program is limited to one-half or one-third of the output channel bitrates (Mbps), which
in turn are dependent on the modulation format. 256-QAM modulation supports up to 45.05 Mbps
(7 MHz bandwidth) or 50.87 Mbps (8 MHz bandwidth), and 64-QAM modulation supports up to
33.79 Mbps (7 MHz bandwidth) or 38.15 Mbps (8 MHz bandwidth).
__ Create a channel assignment plan for the installation site, or modify an existing plan to
incorporate the RF output of the PCS200S. Ensure that up to eight contiguous CATV channel
frequencies are allocated for the PCS200S RF output. The PCS200S uses a 256-QAM or
64-QAM modulation format, thereby occupying approximately 56 MHz or 64 MHz (depending
on channel bandwidth) of frequency spectrum.
The RF start channel frequency is user-assigned, in KHz, during system setup (in the Admin
Client), and the remaining channel frequencies (up to seven) are then automatically assigned in
accordance with the specified bandwidth. For example, if the RF start channel frequency assign-
ment is 57000 KHz with a 7 MHz bandwidth, the seven remaining channel frequencies will be
64000 KHz, 71000 KHz, 78000 KHz, 85000 KHz, 92000 KHz, 99000 KHz, and 106000 KHz.
The highest available RF channel frequency for the PCS200S is 861000 KHz.
__ Find a location on the frequency spectrum that is free of existing noise.
Video Channel Assignments for IP Output with Solid State Drive
Each IP stream is limited to 19.4 Mbps.
__ The PCS200S 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 multi-
cast 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 PCS200S. Ensure that up to 23 unused and unreserved IPv4
multicast addresses, within the designated range 224.0.0.0 to 239.255.255.255, are allocated
for the PCS200S IP output.
The IP start channel is user-assigned during system setup (in the Admin Client), and the
remaining channel assignments are then automatically incremented. 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.
__ Reserve one User Datagram Protocol (UDP) port for the multicast data streams. You can use
the system default (1234) or another unassigned port number, for example, 50000, 50001,
etc. The port 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.
ASI Output (Optional)
ASI output supports up to 19.4 Mbps each for GEM and site data (total of 38.8 Mbps).
__ If the system is using ASI output, install the modulator and upconverter that will receive
the ASI output signal from the PCS200S. Refer to the manufacturer's documentation.
