Television, sometimes shortened to TV, is a telecommunication medium for transmitting moving images and sound. The term can refer to a television set or the medium of television transmission. Television is a mass medium for advertising, entertainment, news, and sports.
Television became available in crude experimental forms in the late 1920s, but only after several years of further development was the new technology marketed to consumers. After World War II, an improved form of black-and-white television broadcasting became popular in the United Kingdom and the United States, and television sets became commonplace in homes, businesses, and institutions.
During the 1950s, television was the primary medium for influencing public opinion.[1] In the mid-1960s, colour broadcasting was introduced in the U.S. and most other developed countries. A television channel is a terrestrial frequency or virtual number over which a television station or television network is distributed.
For example, in North America, “channel 2” refers to the terrestrial or cable band of 54 to 60 MHz, with carrier frequencies of 55.25 MHz for NTSC analog video (VSB) and 59.75 MHz for audio (FM), or 55.31 MHz for digital ATSC (8VSB). Channels may be shared by many different television stations or cable-distributed channels depending on the location and service provider
Depending on the multinational band plan for a given regional n, analog television channels are typically 6, 7, or 8 MHz in bandwidth, and therefore television channel frequencies vary as well. Channel numbering is also different.
Digital terrestrial television channels are the same as their analog predecessors for legacy reasons, however through multiplexing; each physical radio frequency (RF) channel can carry several digital subchannels.
On satellites, each transponder normally carries one channel; however multiple small, independent channels can be on one transponder, with some loss of bandwidth due to the need for guard bands between unrelated transmissions. ISDB, used in Japan and Brazil, has a similar segmented mode.
