What Is Philips Home Theatre?
An audio/video entertainment center that has a large-screen TV and high fidelity audio system with at least 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, most home entertainment hardware vendors make A/V equipment for both listening and viewing (see A/V receiver).

How Do Home Theater System Work?
The audio/video (a/v) receiver assembly in a home theater does the same job as the receiver and amplifier assembly in any stereo system: It receives signals from various input devices, like a VCR, DVD player or satellite dish. It interprets and amplifies those signals and then sends them to output devices your television and sound system.
A home theater a/v receiver and amplifier assembly actually combines several different components. Some even have a DVD or other media player built in. You can generally assemble a superior home theater system by buying the components separately, but most people buy one unit that does all these jobs because it is more cost effective.
The receiver’s components are:
- Audio/video inputs for video sources (DVD player, DVR)
- Preamplifier
- Surround-sound decoder (aka signal processor)
- Power amplifiers for each sound channel
- Outputs for speakers and television
The path of the audio and video is pretty straightforward. The source component (DVD player, DVR, etc.) feeds a signal to the receiver unit. You choose which input component you want to feed to your output unit, and the preamplifier selects this signal and amplifies its line level a little bit.
The receiver sends the video on to your television and sends the audio to the decoder. The decoder sorts out the different sound channels from the video signal, and then sends the information to amplifiers for each sound-channel output. These amplifiers are connected to the appropriate speaker or speakers.
A wireless home theater starts by converting the video and audio signal of the content into a radio frequency (typically 2.4GHz or 5GHz) and then transmitting it. The signal is decoded back into video and sound signals that the screen and speakers can use at the receiving end.
