NDS3306I 8in1/16in1/20in1 ISDB-T Modulator
Product Overview
NDS3306I 8in1/16in1/20in1 ISDB-T modulator is the latest generational Mux-modulating device developed by DEXIN. It converts IP streams to 8 (or16, or 20) ISDB-T non-adjacent carriers (50MHz~960MHz) output through the RF interface. The device is also characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation DTV broadcasting system.
Key Features
* 3 GE ports for IP input and output --Version I & II
6 GE ports (4*RJ45, 2*SFP), data1-4 for IP input (RJ45/SFP), data 3-4 for IP output --Version III
* Max 840Mbps for each GE input
* Supports accurate PCR adjusting
* Supports CA filtering, PID remapping and PSI/SI editing
* Supports up to 256 PIDS remapping per channel
* Support 8 IP output through Data1 & Data2 over UDP/RTP/RTSP--Version I
Support 16 IP output through Data1 & Data2 over UDP/RTP/RTSP--Version II
Support 20 IP output through Data3 & Data4 over UDP/RTP/RTSP--Version III
* 8 (or 16, or 20) non-adjacent carriers output, compliant to ISDB-Tb (ARIB STD-B31)
* Support Web-based Network management
