A stereo component that outputs to speakers, and increases the
gain or level of an audio signal. An amplifier doesn’t typically
include a radio.
Also referred to as Enhanced for Widescreen, or Enhanced for
16:9. The process that horizontally shrinks a 16:9 image into a
4:3 space to convert images between widescreen and typical
television image aspect ratio. Used on many DVDs.
The ratio of image width to image height. Common motion-
picture ratios are 1.85:1 and 2.35:1. Television screens are
usually 1.33:1 (also known as 4:3). HDTV is 1.78:1, or 16:9.
A device with several audio and video source inputs that sends a
selected audio/video source input signal to an output device like
speakers or a TV.
Projector screen technology that relies on using individually
controlled tiny mirrors (micro mirrors) to produce an image.
Developed originally by Texas Instruments.
A standalone unit that resembles and functions very much like a
VCR. Like a VCR, DVD recorders all have AV source inputs, as well
it can record TV shows.
The high-resolution form of television. HDTV has 1125 lines of
resolution, or more than five times the video information than
that of a TV set, creating a much crisper, more detailed picture.
The Harmony 650 knows what state all of your devices are in,
such as whether they are on or off and which inputs they were
last using. When it loses track of this information, it becomes
“out of sync”. Your remote can send commands to your devices
to become “in sync” again.
A device that is connected to a set of lights and allows the lights
to be powered or dimmed remotely.
A single unit that is some combination of the functionality of a
DVD, VCR, radio, and amplifier.
The standard video broadcast format used in North America.
