Outline

 STPM-08T  8 in 1 DVB T modulator is an all-in-one device. It has 8 multiplexing channels and 8 DVB-T modulating channels and supports a maximum of 256 IP input through the GE port and 8 non-adjacent carriers (50MHz~960MHz) output through the RF output interface. As this rf modullador is also characterized by a high integrated level, high performance, and low cost. It is very adaptable to the new generation DTV broadcasting system.

Features

*  3 GE ports (max 256 IP in):

    Data1 & Data2 bi-directional ports, max 256 IP in, 8 IP out  

    Data port (located on front panel), max 128 IP in

*  Max 840Mbps for each input

*  Supports accurate PCR adjusting

*  Supports PID remapping and PSI/SI editing

*  Supports up to 180 PIDs remapping per channel

*  Support 8 multiplexed TS over UDP/RTP/RTSP output

*  8 DVB-T non-adjacent carriers output, compliant to ETSI EN300 744 standard

*  Supports RS (204,188) encoding

*  Support Web-based Network management
