The architecture of MythTV is based on the separation of the backend for storing or capturing video (IPTV, DVB-cards, etc.), and the frontend for displaying and forming an interface. The frontend can work simultaneously with several backends, which can be launched both on the local system and on external computers. The functionality is implemented through plugins. There are currently two sets of plugins available - official and unofficial. The range of possibilities covered by plug-ins is quite wide, from integration with various online services and the implementation of a web interface for controlling the system over a network, to tools for working with a web camera and organizing video communication between PCs.
