Biamp 920-00427-00001 TesiraLUX OH-1

Product Overview

The Biamp TesiraLUX OH-1 is an AVB/TSN video decoder that outputs networked video up to and including 4K60 for Tesira media systems. It acts as an AVB listener on the network, receiving synchronized audio and video and driving a display over HDMI with automatic lip-sync management. Built for AV-over-network distribution in lecture halls, courtrooms, and multi-use spaces, the OH-1 delivers low-latency 4K60 video decoding with end-to-end network transit latency of 1.5 frames or less. It is configured entirely through Tesira software as part of an integrated audio and video platform.

Product Description

The TesiraLUX OH-1 functions as a server-class decoder in a Tesira media system, pairing with a TesiraLUX encoder to move high-resolution video across a standard AVB/TSN network. It outputs signals up to 4K60 with 4:4:4 subsampling over a single HDMI port and supports a flexible color space up to Rec. 2020, making it suitable for detail-critical AV distribution. AVB/TSN media can run over 1Gb or 10Gb ports while control travels on a separate 1Gb Ethernet connection, and the decoder supports a virtual matrix of up to 128 devices for large routed systems. Visually lossless M-JPEG compression and end-to-end transit latency of 1.5 frames or less keep video responsive for live presentation and evidentiary playback. The OH-1 handles 8 channels of PCM audio for embedding and de-embedding and provides two mic/line-level analog outputs on removable screw-down connectors for local audio. Integrators can use its four GPIO logic connections and RS-232 serial port to trigger and control displays and room systems. The decoder also supports HDCP 2.2 protected content, automated EDID management with the connected display, and IEEE 802.1X port authentication for secure networks. Built in a half-rack chassis, it pairs with its encoder counterpart, the TesiraLUX IDH-1 video encoder, and other networked AV hardware in the Biamp collection at Creation Networks.

Key Features

• 4K60 video decoding — The decoder outputs video signals up to and including 4K60 with 4:4:4 subsampling over HDMI.
• AVB/TSN networking — It receives synchronized audio and video as an AVB listener over 1Gb or 10Gb media ports.
• Low latency — End-to-end network transit latency is 1.5 frames (25 ms at 60 fps) or less using visually lossless M-JPEG compression.
• Automatic lip-sync — Integrated audio and video on one network enables automatic lip-sync management across the system.
• Embedded and analog audio — It supports 8 channels of PCM audio and provides two mic/line-level analog outputs on removable connectors.
• Control and logic I/O — Four GPIO logic connections and an RS-232 serial port allow display and room control integration.
• Secure, protected content — HDCP 2.2 support, automated EDID management, and IEEE 802.1X port authentication suit managed networks.

Frequently Asked Questions

What does the OH-1 pair with?
The OH-1 is a video decoder designed for Tesira systems and pairs with a TesiraLUX encoder such as the IDH-1 to distribute video across the network.

What resolution does it output?
It outputs video up to and including 4K60 with 4:4:4 subsampling over HDMI, with color space up to Rec. 2020.

How is it installed and networked?
The half-rack decoder connects to an AVB/TSN network over 1Gb RJ-45 or 10Gb SFP+, with a separate 1Gb Ethernet port for control and configuration.

How does it integrate with control systems?
Four GPIO logic connections and an RS-232 serial port allow it to trigger and control displays and third-party room systems.

Does it support protected content?
Yes. The OH-1 supports HDCP 2.2 protected content, automated EDID management, and IEEE 802.1X port authentication.

Is it configured with separate software?
The OH-1 is configured through Tesira software alongside the rest of the media system, unifying audio and video design.

What warranty is included?
The TesiraLUX OH-1 is covered by Biamp's five-year warranty. Contact Creation Networks for design and integration support.
