Overview
DMB-24E-CI Maximum 12‑Tuner to RF Broadcast Transmodulator (with CI Slots)
Key Features
Input Capability: Equipped with 4, 8, or 12 independent DVB‑S/S2 tuners for receiving RF signals.
Conditional Access: Includes 12 CI slots for decrypting encrypted channels using CAM/CAS cards.
Dual‑Path Output: Each RF input channel can be simultaneously output as:
ASI Transport Stream for further transmission over coaxial cable.
IP Output in UDP format, supporting both SPTS and MPTS streams.
RF Output Options: Configurable for 4, 8, or 16 RF carriers.
System Overview
This next‑generation device converts both free‑to‑air (FTA) and encrypted RF programs into alternative RF standards (e.g., DVB‑T, ISDB‑T, ATSC) and IP‑based transport streams. It features a web‑based management interface for easy operation, enabling seamless distribution of all program sources to your local RF infrastructure.
Typical Applications
Ideal for broadcast headends, cable operators, hotels, campuses, and institutions requiring integrated multi‑format signal conversion with conditional‑access support.
Features:
Highly Compact High-Integrate--4/8/12 ch DVB-S/S2/S2X inputs, compliant with FTA and encrypted programs Embedded with CI Slots for discrambling, It can demodulate and descramble multi-channels by integrated 12 DVB-S/S2 satellite tuners with CI slots.
Integrated demodulating and multiplexing--Not only transmodulator, also IP ASI multiplexer
