ISDB-T modulator is the latest generational Mux-modulating device developed by us. It converts IP streams to 8 (or 16, or 24, or 48) 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 aadaptable to newly generation DTV broadcasting system.
1.2 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 8/16 IP output through Data1&2 over UDP/RTP/RTSP--Version I/II
Support 24 IP output through Data3&4 over UDP/RTP/RTSP--Version III
Support 24 IP output through Data3&4 (per daughter card) over UDP/RTP/RTSP--Version IV
8 (or 16, or 24, or 48) non-adjacent carriers output, compliant to ISDB-Tb (ARIB STD-B31)
Support Web-based Network management
