Product Overview
NDS3306I ISDB-T modulator is the latest generational Mux-modulating device developed by DEXIN. It converts IP streams to 24 (or 48) ISDB-T non-adjacent carriers (50MHz~960MHz) output through RF interface. The device is also characterized with high integrated level, high performance and low cost which is adaptable to new generation DTV broadcasting system.
Key Features
l 6 GE ports (4*RJ45, 2*SFP), ports 1-2 for data input (RJ45/SFP), ports 3-4 for data output
l Max 840Mbps for each GE input
l Supports accurate PCR adjusting
l Supports CA filtering, PID remapping and PSI/SI editing
l Supports up to 256 PIDS remapping per channel
l Support 24 IP output through Data ports 3&4 (per daughter card) over UDP/RTP/RTSP
l 24 (or 48) non-adjacent carriers output, compliant to ISDB-Tb (ARIB STD-B31)
l Support Web-based Network management
