Today, home theater implies a real "cinema experience" and therefore a higher quality set of components than the average television provides. A typical home theater would include the following:
- A large, high-quality, display - generally a big-screen television; LCD TV, plasma TV, traditional CRT TV, or a rear-projection TV or possibly a video projector, often HDTV-capable.
- One or more audio/video sources. High quality formats such as DVD or laserdisc are preferred, though old home cinema setups use a stereo VHS VCR. Cable, or C band are also common, as are hard disk based systems.
- An audio system that is capable of surround sound. This usually consists of at least 4 full range speakers with subwoofer for low-frequency effects. Sometimes a specialized decoder is used to allow the playback of newer surround-sound formats.
- Comfortable seating and organization to improve the cinema feel. This might include several comfortable recliners and curtains or subdued room lighting (required for video projectors) to enhance the experience.
- Higher end home theaters commonly also have sound insulation to prevent noise to escape the room, and a specialized coating to ensure correct absorption of the sound in the room.
