www.tbsiptv.com Frequency(100-866Mhz): In the context of configuring this DVB-C modulator and its frequency settings, once the initial frequency and bandwidth are established, the subsequent three frequencies will be automatically and deterministically assigned. For instance, if you set the first frequency to 474 MHz with a bandwidth of 8 MHz, the system will automatically and seamlessly assign the second frequency to 482 MHz, the third to 490 MHz, and the fourth to 498 MHz. - Page 16 www.tbsiptv.com channel capacity guidelines: If you set the encoder bitrate to 8Mbps: 1 Channel will occupy 8Mbps of bandwidth. 2 Channels will occupy a total of 16Mbps (8Mbps x 2). 3 Channels will occupy a total of 24Mbps (8Mbps x 3), which is the maximum recommended configuration for a single frequency to avoid overloading the modulator.
