Video Channel Assignments for RF Output (DVB-C)
Each input programme 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 37.27 Mbps (6 MHz bandwidth),
45.05 Mbps (7 MHz bandwidth) or 50.87 Mbps (8 MHz bandwidth) per channel, and 64-QAM modulation
supports up to 27.95 Mbps (6 MHz bandwidth), 33.79 Mbps (7 MHz bandwidth) or 38.15 Mbps (8 MHz
bandwidth) per channel.
•
Create a channel assignment plan for the installation site, or modify an existing plan to incorporate the RF
output of the PCS500R. Ensure that up to eight contiguous CATV channel frequencies are allocated for the
PCS500R RF output. The PCS500R uses a 256-QAM or 64-QAM modulation format, thereby occupying
approximately 48 MHz, 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 assignment 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 PCS500R is 861000 KHz.

Video Channel Assignments for RF Output (ISDB-T)
Each input programme is limited to one-half or one-third of the output channel bitrates (Mbps). ISDB-T
modulation supports up to 23.23 Mbps (6 MHz bandwidth) per channel.
•
Create a channel assignment plan for the installation site, or modify an existing plan to incorporate the RF
output of the PCS500R. Ensure that up to two (Java application) or three (HTML application) contiguous
CATV broadcast channels are allocated for the PCS500R RF output. The PCS500R occupies up to 18 MHz of
frequency spectrum.
The RF start channel is user-assigned during system setup (in the Admin Client), and the remaining channels
(up to one for the Java application or two for the HTML application) are then automatically assigned in
accordance with the 6 MHz bandwidth. For example, if the RF start channel assignment is channel 7 on a server
configured for the HTML application, the two remaining channels will be 8 and 9.
The data channel number must be between 7 and 69. Thus, for example, to allocate all three channels available
for PCS500R RF output with the HTML application, the RF start channel must be set no higher than 67.
Note
: The Pro:Centric server cannot generate channels 13 and 14 simultaneously. If you intend to configure
more than one channel, set the data channel number from 7 to 12 (two channels) or 7 to 11 (three channels)
or from 14 to 68.
