The WDH-4500PM is built with an integrated professional IRD and digital TV modulator. It can provide to broadcaster and operator with multiple functions of digital TV signal reception, re-multiplexing, descrambling, decoding and re-modulation. It supports a wide range of tuner input DVB-S/S2, DVB-T/T2, DVB-C and is used in digital satellite, cable and terrestrial TV networks. The re-multiplexing function enables creation of new SPTS or MPTS from tuner and ASI inputs. This new transport stream may be output to QAM or COFDM modulator, IP and ASI ports. By using the dual DVB common interfaces, WDH-4500PM can decrypt multiple pay TV services in each of the 2 slots. For security application, this equipment can configured as a TS switch among tuner, ASI and TS/IP. The equipment can be controlled and supervised by SNMP, HTTP WEB and proprietary HDMS software.
