A/V receiver (audio/video receiver):
The hub of an audio/video system. A component including Dolby Pro-Logic surround
processing, 5-channel amplification, audio/video switching and input/output jacks, AM/FM tuner, and remote control.
An A/V receiver is different from a stereo receiver, which omits all or most of the video-related features.
Azimuth: The horizontal angle which the radiating lobe of a satellite dish antenna makes in angular degrees, in a
clockwise direction, from a north-south line in the northern hemisphere. In the southern hemisphere, the reference is
the south-north line.
Coaxial cable: A cable that carries both video and audio signals. Used by cable companies and satellite companies.
Component video: Three individual signals used to create a color video image. Component video produces an improved
color picture image compared to standard composite technology because component video separates the three
channels of a color video signal (two chrominance and one luminance which minimizes interference between these
signals).
Composite video: Video signal where the luminance (black and white) and chrominance (color) are combined. NTSC
signals (analog) are composite signals.
CRT (cathode ray tube): Color picture tubes used in standard TV sets. Electron gun generates beams that are guided to
the screen, illuminating small red, green and blue phosphor targets on the front surface. This produces colors and
images on the screen.
DBS (Digital Broadcast System): A system in which signals from a satellite are received by home viewers directly, as
opposed to cable systems that distribute the signal to head-ends and then distribute them to their customers. Your LCOS
TV has an integrated digital broadcast receiver. To complete the system, you only need to install a DIRECTV satellite
dish and order programming from DIRECTV.
Digital: Signal technology that is based on streams of 1s and 0s instead of analog waves. HDTV signals are digital.
DIRECTV: A digital satellite entertainment service in the U.S. offering access to more than 225 channels in digital-
quality picture and sound. According to DIRECTV literature, it is the #1 digital satellite entertainment service in the U.S.
with 9 million subscribers. Your LCOS TV is capable of receiving DIRECTV
®
programming, but you must correctly install
a satellite dish and order programming from DIRECTV.
Discrete Codes: Versions of toggle codes that only perform one function. For instance, a “POWER” button on a remote
would be a toggle, in that when it is used the current power state is reversed. If your device is on, it turns off. If it’s off,
it turns on. A “discrete” code would be a signal that ONLY turns the device on. If it is already on it remains so. These
are most often used to ensure your home theatre components stay completely in sync for powering on and off and
changing inputs.
Such specialized and otherwise hidden codes may also be available for direct access to other “toggled” or “rotating”
functions such as television inputs, receiver soundfield settings and on-screen display modes.
