There is no way to delete a station from the internal channel map, and a re-scan may be needed; or if the new physical channel is found, it may leave the old mapping in place, causing duplicate channels that cannot be accessed through direct entry of the numbers without also pressing the channel-up/down buttons. Many modern TV sets do an ACMS ...
The input digital signal may be over-the-air terrestrial television signals received by a television antenna, or signals from a digital cable system. It normally does not refer to satellite TV , which has always required a set-top box either to operate the big satellite dish , or to be the integrated receiver/decoder (IRD) in the case of direct ...
Outdoor antennas provide up to a 15 dB gain in signal strength and 15-20 dB greater rejection of ghost signals in analog TV. [6] Combined with a signal increase of 14 dB due to height and 11 dB due to lack of attenuating building walls, an outdoor antenna can result in a signal strength increase of up to 40 dB at the TV receiver. [6] Outdoor ...
A typical modern set-top box, along with its remote control - pictured here a digital terrestrial TV receiver by TEAC. A set-top box (STB), also known as a cable box, receiver, or simply box, and historically television decoder or a converter, [1] is an information appliance device that generally contains a TV tuner input and displays output to a television set, turning the source signal into ...
The TIA is capable of inserting a vertical sync signal into the analog output video signal, but it does not have a frame line-counter and so cannot tell when a frame should end. Instead, it is left to the CPU program to trigger vertical sync signals and to count the lines in each frame to determine when a vertical sync signal should be generated.
The diplexer is a different device than a passive combiner or splitter. The ports of a diplexer are frequency selective; the ports of a combiner are not. There is also a power "loss" difference - a combiner takes all the power delivered to the S port and equally divides it between the A and B ports. A diplexer does not.

A standard rack-mount headend. Once a television signal is received, it must be processed. For digital satellite TV signals, a dedicated commercial satellite receiver is needed for each channel that is to be distributed by the cable system; these are usually rack-mountable receivers that are designed to take up less space than consumer receivers.
