Whois & Analysis for soundandvision.com

High-definition television (HDTV) is a television system providing an image resolution that is substantially higher than that of standard-definition television.

Surround sound is a technique for enriching the sound reproduction quality of an audio source with additional audio channels from speakers that surround the listener (surround channels), providing sound from a 360° radius in the horizontal plane (2D) as opposed to "screen channels" (centre, [front] left, and [front] right) originating only from the listener's forward arc.

Consumer electronics or home electronics are electronic or digital equipment intended for everyday use, typically in private homes.

Consumer electronics include devices used for entertainment (flatscreen TVs, DVD players, DVD movies, iPods, video games, remote control cars, etc), communications (telephones, cell phones, e-mail-capable laptops, etc), and home-office activities (e.g., desktop computers, printers, paper shredders, etc).

In British English, they are often called brown goods by producers and sellers, to distinguish them from "white goods" such as washing machines and refrigerators.

In the 2010s, this distinction is not always present in large big box consumer electronics stores, such as Best Buy, which sell both entertainment, communications, and home office devices and kitchen appliances such as refrigerators.

Consumer electronics stores differ from professional audio stores in that the former sells consumer-grade electronics for private use, whereas the latter sells professional-grade electronics designed for use by audio engineers and audio technicians.

An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current).

An amplifier functions by taking power from a power supply and controlling the output to match the input signal shape but with a larger amplitude.

In this sense, an amplifier modulates the output of the power supply based upon the properties of the input signal.

An amplifier is effectively the opposite of an attenuator: while an amplifier provides gain, an attenuator provides loss.

A video projector is an image projector that receives a video signal and projects the corresponding image on a projection screen using a lens system.

All video projectors use a very bright light to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings.

Video projectors are used for many applications such as conference room presentations, classroom training, and concerts.

In schools and other educational settings, they are sometimes connected to an interactive whiteboard.

In the late 20th century they were commonplace in home cinema but later lost market share to large LCD television screens.
