The BLANKOM HDC-7024A is an ultra-high-density professional headend transmodulator designed to receive digital satellite signals across 24 independent DVB-S/S2 transponders simultaneously within a compact 1U chassis. It modulates these incoming transport streams directly into standard DVB-C (QAM) Radio Frequency (RF) carriers for distribution over extensive coaxial cable networks.

No. The HDC-7024A is engineered strictly as a high-density Free-to-Air (FTA) optimization gateway. It omits physical CI slots to prioritize maximum tuner density, power efficiency, and multiplexing throughput per rack unit. For setups requiring hardware CAM decryption, specialized BLANKOM multi-CI modules must be integrated into the headend topology instead.

To efficiently process and distribute the high-density payload ingested from the 24 satellite transponders, the advanced digital modulation engine of the HDC-7024A 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 any of the 24 satellite tuners into custom-tailored QAM output carrier packages.

The digital modulation layer complies fully 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 absolute compatibility with standard edge digital televisions and legacy cable set-top boxes.

The agile RF output section spans the standard digital cable television spectrum from 48 MHz up to 860 MHz. Output parameters can be adjusted individually per carrier via the web interface, ensuring a high Modulation Error Ratio (MER) and exceptionally low phase noise for stable signal distribution across dense coaxial trunk networks.

Yes, full PSI/SI table parsing and regeneration are natively executed by the internal multiplexer core. 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) to deliver a perfectly customized channel lineup to the subscriber end.

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 web administrative interface to decode secured satellite contribution transport feeds.

Remote configuration, real-time bit-rate analysis, tuner locking margins, and RF signal adjustments are managed exclusively via an embedded WebGUI through a standard internet browser over a dedicated, independent 100M Ethernet management interface. This model line does not support SNMP management, prioritizing a highly secure, isolated, 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 safeguard against primary AC power line failures.
