A device used to combine an amplified antenna and satellite signals, which operate at different frequencies, into a signal, which can travel through one cable. An amplified diplexer is used at the antenna and satellite dish location only when the antenna is amplified. A non-amplified diplexer is always used at the satellite receiver location to sep [..]

Attempting to capture the original sound in its entirety and then reproducing the original sound in its entirety. Analog audio has the risk of also reproducing and possibly amplifying noise or distortion. Digital audio is replacing this technology.

Attempting to capture the original video in its entirety and then reproducing the original video in its entirety. Analog video has the risk of also reproducing and possibly amplifying noise or distortion. Digital video is replacing this technology.

A receiver, amplifier, audio and video switcher in one unit encompassing sound decoding with processing allowing for surround sound and multi-channel distribution.

Accepted standard of measure for the diameter of wire or cable. A smaller number gauge represents a larger diameter. e.g. 12 AWG wire is a larger diameter wire than 14 AWG wire.

Primarily a video only signal, transmitting raw video without frequency shifting, multiplexing, or frequency modulation. Imagine the video signal being pushed down the coaxial cable line at a very low frequency (5 MHz). Baseband signaling is used for CCTV (Closed Circuit Television) and for some home automation products.

A shield used around wire or cable to prevent interference caused by Radio Frequency Noise or Interference. Most cable shields are small diameter woven strands of copper or aluminum.

A video and audio signal multiplexed/frequency shifted to a higher frequency in the 54 MHz to 890 MHz range for cable TV and up to 2.2 GHz for the mini dish satellite. This is the common method for video transmission by cable TV and DSS satellite.

Closed Circuit Television, a platform used for security cameras and monitors, which operates on baseband signal. CCTV is very popularin the security community.
