Outline
XLD3348T is a high performance and cost-effective DVB-T modulator designed by Xielide. It has 8 tuner inputs. After multiplexing and modulating process, it gives 4 DVB-T non-adjacent carriers output through one RF port. To meet customers’ various requirements, this device is also equipped with data port for 128 IP input and 4 MPTS output over UDP and RTP. Its pluggable structure design greatly facilitates the change of modules as needed. Moreover, the four CAMs/CIs accompanied and BISS modules can descramble the input programs from 8 Tuners and IP.
XLD3348T can be upgraded and controlled through network system, which allows it widely used in digital broadcasting network and provide good signals for scientific laboratory and DVB-T STB.
