ZeeVee HDB2640-NA HDb2640 4 Channels HD 1080p/i Digital Encoder - Modulator

Product Overview

The ZeeVee HDB2640-NA is a 4-channel HD MPEG-2 digital encoder and QAM modulator in the HDbridge2000 series, accepting HDMI inputs at up to 1080p/i and distributing them as four discrete QAM digital channels over coaxial RF infrastructure. As a ZeeVee HDbridge2000 HD encoder QAM modulator, it is the standard North American four-channel HDMI-to-QAM solution for hotels, universities, sports bars, and commercial facilities with existing coaxial distribution plant. This standalone unit handles up to 1080p/i HD encoding and serves as an MPEG-2 encoder for coax distribution without DirecTV-specific constraints, accepting HDMI from any compatible source. The HDB2640-NA is well-positioned as an HDbridge encoder for hospitality TV and institutional deployments requiring four full-HD QAM channels from HDMI sources.

Product Description

The HDB2640-NA accepts four HDMI video inputs at up to 1080p/i and encodes each to HD MPEG-2 for modulation onto four discrete QAM channels over a facility's coaxial distribution network. HDMI sources can include satellite receivers, cable boxes, media players, streaming devices, and other HD equipment producing unprotected or HDCP-compatible output. Each of the four channels is independently configurable for QAM frequency, encoding bitrate, and audio parameters, allowing the unit to be integrated into an existing channel plan alongside other distribution sources. The standalone rack-mount design requires no external chassis, simplifying headend room installation and keeping equipment counts low in mid-size facilities. The MPEG-2 QAM output is compatible with the full range of QAM-capable televisions deployed in hospitality, healthcare, education, and corporate environments. For installations requiring eight channels, two HDB2640-NA units can be combined; for deployments requiring higher density, the HDbridge3000 modular chassis is the recommended platform. Integrators will find the HDB2640-NA the most practical standalone choice when four HDMI channels need to be distributed over coaxial at 1080p quality.

Key Features

• 4-Channel HDMI Input — Accepts four independent HDMI sources from any compatible HD equipment without source restrictions.
• 1080p/i HD MPEG-2 Encoding — Encodes at up to 1080p/i, delivering full HD quality across all four output channels.
• QAM RF Output — Distributes four independently assignable digital QAM channels over coaxial infrastructure.
• Standalone Rack-Mount Design — No external chassis or command module required for operation.
• Independent Channel Configuration — Each channel is independently configured for QAM frequency, bitrate, and audio settings.

Typical Applications

• Hotels distributing four HD HDMI-sourced channels over coaxial to guest rooms at 1080p
• Sports bars encoding four satellite or cable receiver HDMI outputs to QAM for display distribution
• Universities distributing four HDMI sources over campus coaxial IPTV infrastructure
• Healthcare facilities distributing four HD channels to patient and common area televisions over RF
• Corporate AV headends encoding four HDMI sources for coaxial distribution across a building or campus

Frequently Asked Questions

What is the difference between the HDB2640-NA and HDB2640-DT?

Both are 4-channel HDMI 1080p encoder/modulators. The HDB2640-DT is engineered for DirecTV receiver compatibility; the HDB2640-NA is the general North American version for any HDMI source. If you are not using DirecTV receivers, choose the HDB2640-NA.

Does this unit support 1080p encoding?

Yes. The HDB2640-NA supports HDMI input at up to 1080p/i and encodes to HD MPEG-2 at that resolution.

Can I use this unit for more than four channels?

Multiple units can be combined in a headend room. For higher density, the ZeeVee HDbridge3000 chassis supports up to 24 channels per chassis.

Does the HDB2640-NA include IP streaming output?

No. The HDB2640-NA outputs QAM RF only. For simultaneous QAM and IP output, consider ZeeVee units with dual-output capability such as the ZVPRO810I-NA or the HDbridge3000 blades with IP output.
