Analog television is the original television technology that uses analog signals to transmit video and audio. In an analog television broadcast, the brightness, colors and sound are represented by amplitude, phase and frequency of an analog signal.
NTSC is the first American standard for analog television, published in 1941. In 1961, it was assigned the designation System M. It is also known as EIA standard 170.
Phase Alternating Line (PAL) is a colour encoding system for analog television. It was one of three major analogue colour television standards, the others being NTSC and SECAM. In most countries it was broadcast at 625 lines, 50 fields per second, and associated with CCIR analogue broadcast television systems B, D, G, H, I or K. The articles on analog broadcast television systems further describe frame rates, image resolution, and audio modulation.
A test card, also known as a test pattern or start-up/closedown test, is a television test signal, typically broadcast at times when the transmitter is active but no program is being broadcast.
British Satellite Broadcasting plc (BSB) was a television company, based in London, that provided direct broadcast satellite television services to the United Kingdom.

Integrated Services Digital Broadcasting is a Japanese broadcasting standard for digital television (DTV) and digital radio.
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 and, like that standard, is used mostly in the United States, Mexico, Canada, South Korea and Trinidad & Tobago. Several former NTSC users, such as Japan, have not used ATSC during their digital television transition, because they adopted other systems such as ISDB developed by Japan, and DVB developed in Europe, for example.
Broadcasttelevision systems are the encoding or formatting systems for the transmission and reception of terrestrial television signals.
PALplus is an analogue television broadcasting system aimed to improve and enhance the PAL format by allowing 16:9 aspect ratio broadcasts, while remaining compatible with existing television receivers, defined by International Telecommunication Union (ITU) recommendation BT.1197-1. Introduced in 1993, it followed experiences with the HD-MAC and D2-MAC, hybrid analogue-digital widescreen formats that were incompatible with PAL receivers. It was developed at the University of Dortmund in Germany, in cooperation with German terrestrial broadcasters and European and Japanese manufacturers. The system had some adoption across Europe during the late 1990s and helped introduce widescreen TVs in the market, but never became mainstream.
MicroMV is a proprietary videotape format introduced in October 2001 by Sony. It is the smallest videotape format — 70% smaller than MiniDV or about the size of two US quarter coins; it is also smaller than a Digital8 or DV cassette and slightly smaller than an audio microcassette. It was the first helical scan tape system using MR read head introduced to the market. Each cassette can hold up to 60 minutes of video.
BBC World Service Television, often abbreviated to WSTV, was the name of two BBC international satellite television channels between 1991 and 1995. It was the BBC's first foray into worldwide television broadcasting. In Europe, it was the successor to BBC TV Europe, which it replaced on 11 March 1991. The service was also launched in Asia as a 24-hour news and information service with minor differences, a precursor to BBC World News, launched on 14 October 1991.

Multiplexed Analogue Components (MAC) was an analog television standard where luminance and chrominance components were transmitted separately. This was an evolution from older color TV systems where there was interference between chrominance and luminance.
Analog high-definition television has referred to a variety of analog video broadcast television systems with various display resolutions throughout history.
BBC Select was an overnight television service run by the BBC during the hours when BBC1 or BBC2 had closed down, usually between 2am and 6am. The channel showed programming intended for specialist audiences, such as businessmen, lawyers, nurses and teachers, and was designed to be viewed after broadcast via a video recording. It was funded by a subscription, and most programming was scrambled.
High-definition television (HDTV) describes a television or video system which provides a substantially higher image resolution than the previous generation of technologies. The term has been used since at least 1933; in more recent times, it refers to the generation following standard-definition television (SDTV). It is currently the standard video format used in most broadcasts: terrestrial broadcast television, cable television, satellite television.
