A modern home theater.
home theater definition by American Heritage Dictionary
home theater - Computer Definition
An audio/video entertainment center that has a large-screen TV and hi-fi system with three speakers in the front (left, right and center) and left and right speakers in the rear. Starting in the early 1990s, video inputs were added to stereo receivers, turning them into audio/video (A/V) receivers. Today, almost all home entertainment hardware vendors make A/V equipment for both listening and viewing (see A/V receiver). Audio - Equally Important A good sound system is important in a home theater setup. Realistic high-fidelity greatly enhances movie watching, and in many home theaters, the audio is the more elaborate and costly part of the system. See home theater in a box, soundbar, surround sound, digital media server, videophile and audiophile.
