MediaPortal is an open-source media player and digital video recorder software project, often considered an alternative to Windows Media Center. It provides a 10-foot user interface for performing typical PVR/TiVo functionality, including playing, pausing, and recording live TV; playing DVDs, videos, and music; viewing pictures; and other functions. Plugins allow it to perform additional tasks, such as watching online video, listening to music from online services such as Last.fm, and launching other applications such as games. It interfaces with the hardware commonly found in HTPCs, such as TV tuners, infrared receivers, and LCD displays.
The MediaPortal source code was initially forked from XBMC (now Kodi), though it has been almost completely re-written since then. MediaPortal is designed specifically for Microsoft Windows, unlike most other open-source media center programs such as MythTV and Kodi, which are usually cross-platform.
