The Evertz 7881DEC2-MP2 is a professional dual-channel MPEG-2 decoder module designed for the Evertz 7800 series modular platform. Its primary function is to receive and decode two independent streams of MPEG-2 compressed video, which can be either standard definition (SD) or high definition (HD), and output the resulting uncompressed serial digital video (SDI). This process is essential in broadcast facilities for ingesting content that arrives in a compressed format—such as satellite feeds, network contributions, or files from servers—and converting it back to baseband SDI for further processing, monitoring, playout switching, or archiving. The decoder handles both the video and associated audio streams, typically outputting the audio embedded within the SDI signal.

Engineered for reliability and integration within a 24/7 broadcast environment, this dual decoder module maximizes processing density within a single card slot of the modular chassis. It accepts transport streams via common broadcast interfaces, likely ASI (Asynchronous Serial Interface) or possibly IP. The module performs full MPEG-2 decoding (Main Profile at Main Level for SD, Main Profile at High Level for HD) with robust error handling to maintain picture stability. It integrates seamlessly into the Evertz 7800 series frame, leveraging the chassis's power, cooling, and centralized control system, allowing for remote management, configuration, and monitoring via Evertz's software platforms.

As a key component in modern broadcast playout and distribution chains, the 7881DEC2-MP2 enables the efficient and reliable conversion from compressed delivery formats to the uncompressed domain required for high-quality broadcast operations. Its dual-channel design makes it a space-efficient solution for facilities managing multiple channels. By providing stable, high-quality decoding within a scalable modular system, it supports the seamless on-air presentation of content from various compressed sources.
