NDS3308T 8in1/16in1/24in1 DVB-T Modulator
Product Overview
NDS3308T 8in1/16in1/24in1 DVB-T modulator is an all-in-one device developed by DEXIN. It supports maximum 256 (or 512, or 768) IP input through the GE/SFP port and has 8 (or 16, or 24) multiplexing channels and 8 (or 16, or 24) DVB-T modulating channels of non-adjacent carriers (50MHz~960MHz). 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
* 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 input
* Supports accurate PCR adjusting
* Supports PID remapping and PSI/SI editing
* Supports up to 180 PIDs remapping per channel
* Support 8 (or 16, or 24) multiplexed TS over UDP/RTP/RTSP output
* 8 (or 16, or 24) DVB-T non-adjacent carriers output, compliant to ETSI EN300 744 standard
* Supports RS (204,188) encoding
* Support Web-based Network managementProduct Overview
