ZeeVee HDB2840-NA 4 Channel HD/1080p Video Encoder/QAM Modulator

Product Overview

The ZeeVee HDB2840-NA is a 4-channel HD MPEG-2 digital encoder and QAM modulator in the HDbridge2000 series, designed specifically for unencrypted HDMI sources and supporting resolutions up to 1080p for coaxial QAM distribution. As a ZeeVee HDbridge2000 HD encoder QAM modulator for HDCP-free content, it is the appropriate choice when four HDMI sources that do not carry HDCP copy protection need to be encoded and distributed over a facility's existing coaxial infrastructure. This standalone unit targets corporate AV, digital signage, in-house content production, and institutional AV environments where locally generated video is the primary source type and HDCP authentication is not applicable. The HDB2840-NA provides an MPEG-2 encoder for coax distribution without the HDCP-related handshaking that can complicate encoding from unprotected sources on standard encoder units.

Product Description

The HDB2840-NA accepts four channels of unencrypted HDMI video at up to 1080p and encodes each to HD MPEG-2, modulating the output onto four discrete QAM channels for delivery over coaxial distribution plant. Unencrypted HDMI sources are common in professional AV installations where content originates from internal systems: presentation computers, media players running custom content, AV processors, IP cameras with HDMI outputs, and broadcast production equipment. This encoder handles those sources directly without HDCP handshake complexity, producing clean MPEG-2 QAM output ready for distribution to any QAM-capable display. Each of the four channels is independently configurable for QAM frequency, encoding bitrate, and audio parameters. The standalone rack-mount form factor requires no external chassis, and the unit fits within standard AV headend rooms. For corporate campuses distributing presentation content, digital signage networks requiring reliable HDMI-to-QAM encoding, or educational facilities broadcasting unencrypted programming over coaxial, the HDB2840-NA provides a direct four-channel solution in the ZeeVee HDbridge2000 product line.

Key Features

• 4-Channel Unencrypted HDMI Input — Designed for HDCP-free sources, encoding four channels without HDCP authentication complexity.

• QAM RF Output — Delivers four independently assignable digital QAM channels over coaxial infrastructure.
• Standalone Operation — Self-contained rack-mount unit with no external chassis required.
• Independent Channel Configuration — Each channel configured separately for QAM frequency, bitrate, and audio settings.

Typical Applications

• Corporate campuses distributing presentation or digital signage content from unencrypted HDMI sources over coaxial RF
• Educational institutions encoding locally produced, HDCP-free programming for campus coaxial distribution
• Digital signage networks requiring stable HDMI-to-QAM encoding from media players or custom content systems
• Government and institutional facilities distributing internally produced video over RF infrastructure
• Sports venues encoding camera or replay system HDMI outputs for QAM distribution to concourse and suite displays

Technical Specifications

Frequently Asked Questions

What does "unencrypted HDMI" mean for this unit?

The HDB2840-NA is engineered for HDMI sources that do not use HDCP copy protection. Sources such as computers, presentation systems, local media players, and cameras typically output HDCP-free HDMI. This unit encodes those sources reliably without HDCP authentication issues that can affect encoding from copy-protected sources on standard hardware.

Can the HDB2840-NA accept HDCP-protected sources?

No. This unit is designed for unencrypted (HDCP-free) HDMI input. For HDCP-protected sources, the HDB2640-NA is the appropriate model in the HDbridge2000 series.

Is an external chassis required?

No. The HDB2840-NA is a standalone rack-mount unit that does not require an external chassis.

What is the maximum resolution this unit encodes?

The HDB2840-NA supports HDMI input and MPEG-2 encoding at up to 1080p for full HD QAM channel output.
