What is an example of regional variation among national pay television channels in the U.S.?
Television Channel: A terrestrial frequency or virtual number over which a television station or television network is distributed. Channel Numbering: Analog television channels are typically 6, 7, or 8 MHz in bandwidth, and frequencies vary. Digital terrestrial television channels are the same as their analog predecessors for legacy reasons. Interference Prevention: Preventing interference between terrestrial channels in the same area is accomplished by skipping at least one channel between two analog stations' frequency allocations. Terrestrial Television Station: A type of terrestrial station that broadcasts both audio and video to television receivers in a particular area. Non-terrestrial Television Channels: Alternative means of distribution such as direct-to-home satellite and cable television have been introduced. Television channels specifically built to run on cable or satellite blur the line between TV station and TV network. Programming Providers: Content providers like TLC cannot run broadcast equipment like a station, and they do not regularly provide content to licensed broadcasters either. Legal Distinction: The terms "programming service" or "programming undertaking" may be used instead of the latter definition to differentiate between a (location) channel and a television channel. Cable Network: The term "cable network" has entered into common usage in the United States in reference to such channels. Virtual Channels: On digital platforms, such (location) channels are usually arbitrary and changeable, due to virtual channels. Satellite: 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. Regional Variation: Geographical separation among "national" pay television channels in the U.S. varies from programming to regionalized advertising inserted by the local cable company.
