Enigma 2

Enigma 2 (often stylized as Enigma2 or E2) is a Linux-based embedded operating system primarily used for digital television receivers, particularly satellite and cable receivers. It is not to be confused with the Enigma machine, a World War II-era encryption device.

Enigma 2 provides a framework for manufacturers and developers to create custom user interfaces and functionalities for their receivers. This open-source nature allows for a high degree of customization, ranging from channel lists and electronic program guides (EPGs) to advanced features like media streaming and plugin support.

Key characteristics of Enigma 2 include its modular design, which allows developers to create and integrate plugins that extend the receiver's capabilities. These plugins can provide access to various online services, media players, and other functionalities. The operating system also supports a wide range of hardware configurations and codecs, enabling compatibility with different broadcast standards and media formats.

Because of its flexibility and open architecture, Enigma 2 is popular among hobbyists and enthusiasts who desire greater control over their digital television experience. Various third-party images (operating system distributions) are available, each offering a different set of features and pre-installed plugins. However, configuring and maintaining an Enigma 2 receiver often requires a degree of technical knowledge.
