An HD home theater is one that includes all the above with a widescreen high-definition display which is one capable of creating images with at least 720 lines of resolution. In addition, there must be at least one source capable of providing HDTV content. Today that list includes an HDTV over-the-air receiver, a high definition cable box, a high definition satellite receiver or a Blu-Ray player. According to the Society of Motion Picture and Television engineers (SMPTE), a proper movie theater experience requires the screen should occupy at least 30 degrees of viewing which translates to sitting just 1.584 times the screen diagonal measurement (16:9 aspect).

Entry level home theatre projectors are currently under $1000. TYPES OF HOME THEATRES Home theater used to consist of commercial 35 m
