ShowShifter, now obsolete, was a proprietary, commercial digital video recorder (DVR) and home theater PC (HTPC) software for Windows. ShowShifter offered features such as TV recording, PVR facilities, EPG, audio and video Jukebox, and a picture viewer from within a user interface designed to be used by a remote control at a comfortable viewing distance from the video display, hence the term 10-foot user interface.
