QAM (DVB-C) Transmodulator with DVB-S/S2 & IPTV Input, 4 Tuners for 4 Satellite Transponders

BLANKOM HDC-7004 DVB-C Transmodulator

Professional 4x DVB-S2X & IP to 4x QAM Headend Solution

The BLANKOM HDC-7004 represents the pinnacle of 5th-generation signal processing, engineered specifically for broadcasters, system integrators, and commercial Headend operators. Operating as a highly versatile Transmodulator, the HDC-7004 ingests up to 4 DVB-S/S2/S2X satellite transponders alongside a massive payload of up to 128 IP streams, multiplexing and modulating them into 4 adjacent DVB-C (QAM) RF carriers.

Uncompromising Industrial Design

Unlike standard commercial alternatives that may suffer from thermal throttling, packet loss, or degraded MER under peak loads, the BLANKOM HDC-7004 is manufactured through strict OEM production standards to guarantee heavy and demanding use. Our hardware ensures an exceptionally clean RF output with an MER of ≥ 40 dB, significantly outperforming competitor models in its class.

Seamless BLANKOM Ecosystem Integration

Full compatibility is central to our engineering philosophy. The HDC-7004 integrates flawlessly with all other BLANKOM encoders, IRDs, and IPTV servers. Whether you are scaling an existing network or building a new broadcast facility from the ground up, you are guaranteed uninterrupted interoperability.

Core Advantages Over Competitor Solutions

• Superior Signal Integrity: While many competitors struggle to maintain RF clarity when fully loaded, the HDC-7004 retains an aggressive MER of ≥ 40 dB and ACLR of -60 dBc, ensuring pristine artifact-free transmission.

• Comprehensive Simulcrypt Scrambling: Built-in capability to handle up to 4 CA systems simultaneously without requiring expensive supplementary hardware or hidden licensing fees.

• Hybrid Output Architecture: Outputs the processed multiplexes via both RF (DVB-C) and IP (4x MPTS), providing crucial flexibility for operators transitioning from legacy coaxial networks to IPTV.
