ZJ3308AT 8 in 1 ATSC Modulator
Product Overview
ZJ3308AT 8 in 1 ATSC modulator is newly designed product supporting IP input. It has 8 multiplexing channels and 8 ATSC modulating channels, and supports maximum 256 IP input through the GE port. ZJ3308AT has a powerful output capacity with 8 non-adjacent carriers (50MHz~960MHz) output through the RF output interface. The system of this device can be on line controlled and upgraded through network, which can be widely used in ATSC digital broadcasting network setup and the testing for ATSC set top box design.
Key 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 ATSC non-adjacent carriers output, compliant to ATSC A/53 standard
● Supports RS (208,188) encoding
● Support Web-based Network management
