SC-4177 64ip udp input 4dtmb output iptv dtmb modulator
Overview
4in1 IP DTMB Modulator supports 64*IP (TS over UDP) input and 4*DTMB RF output, supporting BCH/LDPC encoding, interleaving, and baseband shaping. The input IP signal can be sent to signal processor and be converted to TS (transport stream). It integrates multiplexer and DTMB modulator. It suits 1U rack and can be configured by front panel LCD and NMS (network management software). Its high-integrated and cost-effective design makes it widely used in varieties of digital broadcasting distribution systems.
Features
u 8M cache, anti-burst stream
u PCR correction
u Support 64*IP (TS over UDP) input
u Support multiplexer
u Real-time transport stream monitoring
u LCD/Keyboard control by front panel and network management by Ethernet
