Overview
FU4443 (V2) 16in1 (or 32in1) DVB-C modulator is an all-in-one device developed by FMUSER. It supports maximum 1024 IP input through the 4 GE/SFP port and also 6 ASI input. After multiplexing, scrambling 16(or 32) and DVB-C modulating, it gives 16(or 32) non-adjacent carriers (50MHz~960MHz), 2 ASI output and 16 or 32 IP (MPTS) output as mirror of carriers. The device is characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation DTV broadcasting system. Key Features: 4 GE/SFP ports (max 1024 IP in):; Data1 is bi-directional ports, max 1024 IP in, 16/32 IP out; Data2&3&4 ports only for input; Supports accurate PCR adjusting; Max 840Mbps for each input; Supports up to 256 PIDs remapping per channel; Supports 6 ASI input and 2 ASI output; Support 16 (or 32) multiplexed TS over UDP/RTP/RTSP output; 16(or 32) DVB-C non-adjacent carriers output, compliant to DVB-C (EN 300 429) and ITU-T; Supports RS(204,188) encoding; Support Web-based Network management
