Home cinema, also commonly called home theater or home theatre, refers to home entertainment systems that seek to reproduce a movie theater experience and mood using video and audio equipment in or outside a private home. As of 2015, system users typically use a large projected image from a video projector or a large flat-screen high-resolution HDTV system, a movie or other video content on a DVD or high-resolution Blu-ray disc, which is played on a DVD player or Blu-ray player, with the audio augmented with five or more surround sound speakers and at least one low-frequency subwoofer.
