Analog television is the original television technology that uses analog signals to transmit video and audio. [1] In an analog television broadcast, the brightness, colors and sound are represented by amplitude , phase and frequency of an analog signal.
Advanced Television Systems Committee (ATSC) standards are an international set of standards for broadcast and digital television transmission over terrestrial, cable and satellite networks. It is largely a replacement for the analog NTSC standard – like that standard – is used mostly in the United States , Mexico , Canada , South Korea ...
A cable channel (sometimes known as a cable network) is a television network available via cable television. Many of the same channels are distributed through satellite television .

Analog television system by nation Analog color television encoding standards by nation. Every analog television system bar one began as a black-and-white system. Each country, faced with local political, technical, and economic issues, adopted a color television standard which was grafted onto an existing monochrome system such as CCIR System M, using gaps in the video spectrum (explained ...
Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable television (CATV) system. It is used by many cable television operators to provide cable Internet access over their existing hybrid fiber-coaxial (HFC ...
This series explores aspects of America that may soon be just a memory -- some to be missed, some gladly left behind. From the least impactful to the most, here are 25 bits of vanishing America. I ...
L-carrier also carried the first television network connections, though the later microwave radio relay system soon became more important for this purpose. Type L-3 was used for a short time for coast-to-coast network television feeds, but the advent of NTSC color was the cause for the move to Type TD microwave radio.
The OSC carries information about the multi-wavelength optical signal as well as remote conditions at the optical terminal or EDFA site. It is also normally used for remote software upgrades and user (i.e., network operator) Network Management information. It is the multi-wavelength analog to SONET's DCC (or supervisory channel).
