This high-density professional transmodulator is designed to receive digital satellite signals across 16 independent DVB-S/S2 transponders and modulate them directly into standard DVB-C (QAM) Radio Frequency (RF) channels. This allows cable operators to convert extensive satellite channel lineups for seamless distribution over existing local or regional coaxial cable networks.

No. This specific 16-tuner transmodulator model is engineered strictly as a high-density Free-to-Air (FTA) optimization gateway. It omits physical CI slots to maximize tuner input density and multiplexing throughput within a compact 1U framework. For setups requiring hardware-based CAM decryption, specialized BLANKOM multi-CI modules must be deployed in the headend topology instead.

To efficiently process and distribute the high-density payload ingested from the 16 satellite transponders, the advanced digital modulation engine of the HDC-7016A is engineered to generate exactly 16 independent QAM RF carriers simultaneously. This configuration allows operators to bundle and broadcast extensive multiplexed digital TV and radio lineups over a single coaxial physical distribution network with optimal bandwidth allocation.

The unit incorporates a powerful internal digital multiplexer. Unlike basic transparent pass-through loop converters, it enables headend engineers to demultiplex incoming satellite transport streams, perform selective PID filtering or PID remapping, and freely recombine elementary video and audio streams from different satellite tuners into custom-tailored QAM output carrier packages.

The digital modulation layer complies strictly with ITU-T J.83A and J.83B digital cable specifications. It supports 16QAM, 32QAM, 64QAM, 128QAM, and 256QAM constellations with an adjustable symbol rate up to 7.0 Msps per carrier, ensuring flawless tuning across standard digital television sets and legacy edge set-top boxes.

The device incorporates an agile RF output section covering the standard digital cable television spectrum from 48 MHz up to 860 MHz. It features a high-performance modulation circuit that guarantees a superior MER (Modulation Error Ratio) and exceptionally low phase noise, preventing signal degradation or pixelation across extensive coaxial trunk lines.

Yes, full PSI/SI table parsing and regeneration are natively executed by the internal multiplexer engine. The unit automatically processes and rebuilds PAT, PMT, NIT, and SDT metadata tables. This grants operators the flexibility to manually customize service names, provider identifiers, and Logical Channel Numbering (LCN) directly via the configuration layout.

Yes. Despite being an FTA gateway without physical CI/CAM module slots, it features embedded software-assisted BISS (Basic Interoperable Scrambling System) Mode 1 and Mode E decryption. Headend engineers can input hexadecimal keys directly via the administrative interface to decode secured satellite contribution transport feeds.

Remote configuration, real-time bit-rate analysis, tuner locking margins, and RF signal configuration are managed exclusively via an embedded WebGUI through a standard internet browser over a dedicated, independent Ethernet management interface. This model line does not support SNMP management, ensuring a highly secure, lightweight, and low-overhead administration environment.

Housed in a rugged standard 19-inch 1U rack-mount industrial metal enclosure, the unit is engineered for demanding 24/7/365 commercial headend uptimes. It relies on intelligent active cooling fans for thermal stability and can be provisioned via our technical Ordering Guides with dual redundant power supplies to protect the distribution path against primary AC power line failures.
