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 PCS400R. Ensure that
up to eight contiguous CATV channel frequencies are allocated for the PCS400R RF output. The PCS400R 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 57,000 KHz with a 7 MHz bandwidth, the seven remaining channel frequencies will be 64,000 KHz, 71,000 KHz, 78,000 KHz,
85,000 KHz, 92,000 KHz, 99,000 KHz, and 106,000 KHz.
The highest available RF channel frequency for the PCS400R is 861,000 KHz.
• Find a location on the frequency spectrum that is free of existing noise.
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 PCS400R. Ensure that
up to two (Java application) or three (HTML application) contiguous CATV broadcast channels are allocated for the PCS400R RF output. The
PCS400R 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 PCS400R 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.
