Video/Audio Decoder Module

Evenlode Air Data Terminal Equipment

  • Capable of decoding two video
    signals up to 4K (option dependent) using Advanced Video Coding (H.264) and High
    Efficiency Video Coding (H.265).
  • Lightweight, low power unit.
  • Receives a single Asynchronous Serial Interface signal containing an MPEG-2 Part 1 Transport Stream.

Product Description

The Evenlode Video/Audio Decoder Module is a lightweight, low power unit ruggedized for installation on to an air platform. The Module has been designed to be used in conjunction with the Evenlode Air Data Terminal. The Video Decoder Module contains a single video decoder. The Module also contains an audio output. 

Control and monitoring of the Module is achieved via serial interface. When used in conjunction with the Evenlode data terminal this control and monitoring interface is presented as part of the Evenlode system Graphical User Interface. The Video Decoder Module may also be used independently of the Evenlode system to decode the video and audio sources. 

At a weight of only 600 grams (approx.) and a size of 139 x 38 x 200 mm (approx.) the Module is suitable for lightweight air platforms. The module incorporates an aluminum housing and rugged connectors.
