Overview
DMB-24E-CI Maximum 12 Tuner to RF Broadcast Transmodulator with CI Slots
Product Overview:
The DMB-24E-CI is a professional RF broadcast transmodulator equipped with CI slots, supporting a maximum of 12 DVB‑S/S2 satellite tuners for signal reception. It includes 12 independent CI slots for CAM and CAS cards to enable decryption of encrypted channels. Each RF input can be output simultaneously as an ASI transport stream for transmission over coaxial cable, and as IP output in UDP format (SPTS/MPTS). The RF output is configurable with 4, 8, or 16 carrier options.
Key Features:
Converts both FTA (Free‑to‑Air) and encrypted RF programs into alternative RF standards and IP‑based transport streams.
Provides full web‑based management for easy operation, enabling seamless distribution of all program sources to your local RF infrastructure.
Application:
Ideal for broadcast headends, cable TV operators, hotels, and institutions requiring flexible multi‑format signal conversion and integrated CI‑based conditional access handling.
Features:
Highly Compact, High‑Integration Design – Supports 4, 8, or 12 DVB‑S/S2/S2X inputs, compatible with both FTA and encrypted programs. Equipped with integrated CI slots for decryption, the unit can demodulate and descramble multiple channels through 12 built‑in DVB‑S/S2 satellite tuners with CI interfaces.
Integrated Demodulation and Multiplexing – Functions not only as a transmodulator, but also as an IP/ASI multiplexer.
Mixed Multi‑Source Input – Accepts a combination of FTA tuners, encrypted tuners, and HDMI inputs via modular configuration. Supports up to 6 plug‑in modules, with options including:
1 module: 4× FTA tuners
1 module: 4× HDMI inputs
1 module: 2× tuners + CI slots
Professional Broadcast‑Grade Features – Includes powerful PSI/SI regeneration, service‑level multiplexing, and PID filtering.
Web‑Based Management – Offers user‑friendly web GUI for network management and software upgrades.
