Overview
The DMB-24E multi-channel FTA tuner-to-RF broadcast transmodulator is a high-density integrated device featuring both demodulation and modulation capabilities, intended for digital broadcast headend setups. It can accept up to 24 FTA tuner inputs and convert them into 4, 8, or 16 non-adjacent carrier outputs with internal multiplexing. It also supports 128 MPTS/SPTS UDP/IP input streams, and delivers 1 MPTS plus 127 SPTS UDP/RTP output streams via its DATA port, while allowing TS re-multiplexing through dual ASI input ports.
As a next-generation solution, this device converts RF program signals into alternative RF formats and IP transport streams, with simple web-based administration for efficient distribution of all channels to the local RF transmission network.
Features:
A wide selection of input types is available, allowing flexible configuration based on actual signal sources:
1: Support for up to 24 FTA tuner inputs2: Combination of two tuner types plus HDMI input – for instance, 8 DVB‑S/S2 + 8 DVB‑T/T2 + 8 HDMI3: Single tuner type together with HDMI input – such as 12 DVB‑S/S2 + 8 HDMI
Operation and management are supported through both LCD panel and web interface. The front-mounted color LCD display enables convenient system setup, channel monitoring, firmware version checking, and IP address detection without using a computer.
For professional broadcast television applications, the device supports PCR correction, PCR interval adjustment, and LCN (Logical Channel Number) configuration.
Multi-carrier RF output is provided, with optional configurations of 4/8/16 carriers for DVB‑T, ISDB‑T, ATSC or DVB‑C, as well as 32 QAM DVB‑C, depending on the total number of program channels required.
