Whois & Analysis for colorviewfinder.co

Headphones (or head-phones in the early days of telephony and radio) are a pair of small loudspeaker drivers worn on or around the head over a user's ears.

They are electroacoustic transducers, which convert an electrical signal to a corresponding sound.

Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear.

Headphones are also known as earspeakers, earphones or, colloquially, cans.

Circumaural and supra-aural headphones use a band over the top of the head to hold the speakers in place.

The other type, known as earbuds or earpieces consist of individual units that plug into the user's ear canal.

In the context of telecommunication, a headset is a combination of headphone and microphone.

Headphones connect to a signal source such as an audio amplifier, radio, CD player, portable media player, mobile phone, video game console, or electronic musical instrument, either directly using a cord, or using wireless technology such as Bluetooth, DECT or FM radio.

The first headphones were developed in the late 19th century for use by telephone operators, to keep their hands free.

Initially the audio quality was mediocre and a step forward was the invention of high fidelity headphones.

In radio communications, a radio receiver (receiver or simply radio) is an electronic device that receives radio waves and converts the information carried by them to a usable form.

It is used with an antenna.

The antenna intercepts radio waves (electromagnetic waves) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information.

The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation.

Home cinema, also called home theater or home theatre, refers to home entertainment audio-visual systems that seek to reproduce a movie theater experience and mood using consumer electronics-grade video and audio equipment that is set up in a room or backyard of a private home.

In the 1980s, home cinemas typically consisted of a movie pre-recorded on a LaserDisc or VHS tape; a LaserDisc or VHS player; and a heavy, bulky large-screen cathode ray tube TV set.

In the 2000s, technological innovations in sound systems, video player equipment and TV screens and video projectors have changed the equipment used in home theatre set-ups and enabled home users to experience a higher-resolution screen image, improved sound quality and components that offer users more options (e.g., many of the more expensive Blu-ray players in 2016 can also "stream" movies and TV shows over the Internet using subscription services such as Netflix).

The development of Internet-based subscription services means that 2016-era home theatre users do not have to commute to a video rental store as was common in the 1980s and 1990s (nevertheless, some movie enthusiasts buy DVD or Blu-ray discs of their favourite content).

A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming.

Modern computers have the ability to follow generalized sets of operations, called programs.

These programs enable computers to perform an extremely wide range of tasks.

Color depth or colour depth (see spelling differences), also known as bit depth, is either the number of bits used to indicate the color of a single pixel, in a bitmapped image or video frame buffer, or the number of bits used for each color component of a single pixel.

For consumer video standards, such as High Efficiency Video Coding (H.265), the bit depth specifies the number of bits used for each color component.

When referring to a pixel, the concept can be defined as bits per pixel (bpp), which specifies the number of bits used.

When referring to a color component, the concept can be defined as bits per component, bits per channel, bits per color (all three abbreviated bpc), and also bits per pixel component, bits per color channel or bits per sample (bps).

Color depth is only one aspect of color representation, expressing how finely levels of color can be expressed (a.k.a.

color precision); the other aspect is how broad a range of colors can be expressed (the gamut).

The definition of both color precision and gamut is accomplished with a color encoding specification which assigns a digital code value to a location in a color space.
