DMB-5100E Series Professional IP to RF Digital Modulator

The DMB-5100E Series IP to RF Modulator is a broadcast-grade, highly integrated all-in-one digital TV front-end device, engineered to bridge IP-based media delivery systems and traditional RF transmission networks. It is purpose-built to receive program content transmitted over IP backbone networks, private LANs, or CDN platforms, and convert the media streams into standard-compliant digital RF signals for seamless distribution over coaxial cable infrastructure, terrestrial DTV transmission systems, and in-building TV distribution networks. This device combines high-capacity stream processing, professional TS stream management, and multi-standard RF modulation into a single compact platform, making it a streamlined, cost-effective core solution for building end-to-end digital TV broadcasting systems.

At its input layer, the DMB-5100E is equipped with 3 independent Gigabit Ethernet (GigE) data ports, delivering exceptional IP stream access and processing capacity. Each data port supports concurrent reception of up to 128 IP streams (both SPTS and MPTS) via mainstream UDP/RTP transport protocols, enabling the device to handle a maximum of 384 IP input streams simultaneously, easily meeting the needs of medium-to-large scale program distribution projects. Complementing the IP inputs, the device also integrates 6 independent ASI input interfaces, providing seamless access to local program sources from traditional ASI-based broadcast equipment. It supports mixed processing of IP and ASI input signals, allowing operators to freely combine, schedule, and route content from both IP network and local ASI sources, eliminating the need for additional standalone multiplexing equipment and simplifying the system architecture.

For RF output, the DMB-5100E delivers industry-leading modulation performance and flexible configuration options, fully aligned with global mainstream digital terrestrial TV transmission standards. It supports modulation of the pre-processed IP and ASI streams into 16 independent non-adjacent RF carriers, with full compatibility for ISDB-T, DVB-T, and ATSC standards. Unlike fixed-frequency modulation devices, its non-adjacent carrier design allows users to freely plan and configure the frequency point of each RF carrier within the standard operating band, without binding to fixed frequency intervals. This flexibility enables perfect adaptation to regional spectrum planning regulations, avoids co-channel and adjacent-channel interference in complex transmission environments, and maximizes the utilization of available spectrum resources. Each RF carrier supports independent parameter configuration, including modulation scheme, constellation mapping, bandwidth, and guard interval, allowing operators to optimize transmission performance based on coverage distance, channel conditions, and terminal compatibility.

Powerful modulation performance---Includes 3xGigabit Ethernet DATA Ports for IP input, each data port support 128*IP(SPTS/MPTS) UDP, RTP & Unicast / Multicast

Multi-RF Carriers out for hundreds of programs---Receive up to hundreds of ip streams, re-multiplex them as wanted,and output up 16 DVB-T/ATSC/ISDB-T multi-channel RF Frequencies with the ability to distribute hundreds of SD HD programs over Coax/terrestrial transmission
