NORTH AMERICAN CABLE TELEVISION FREQUENCIES Meaning and
Definition
-
North American Cable Television Frequencies refer to the designated range of electromagnetic wave frequencies that are used for the transmission of cable television signals in North America.
Cable television, commonly known as cable TV, is a system of delivering television programming to consumers through coaxial or fiber-optic cables instead of over-the-air broadcast signals. These frequencies are specifically allocated for cable television transmission by regulatory bodies in North America.
The North American cable television frequencies range from approximately 54 MHz to 1002 MHz, divided into different frequency bands or channels. Each channel carries a specific frequency range that allows the transmission of multiple television programs simultaneously. This frequency allocation ensures that cable operators can provide a wide variety of channels and services to their subscribers.
The frequencies are typically transmitted using a process called modulation, where the original video and audio signals are converted into a form that can be carried by the cable. The transmitted signals are then received by cable television subscribers' set-top boxes or cable-ready televisions, which demodulate the signals back into the original content for viewing.
The allocation and regulation of cable television frequencies in North America are overseen by organizations such as the Federal Communications Commission (FCC) in the United States and the Canadian Radio-television and Telecommunications Commission (CRTC) in Canada. These regulatory bodies ensure that the frequency allocation is organized and managed to prevent interference and to maintain the quality and reliability of cable television services.
