Cable 1(television, radio, Internet) is a commercial service that links televisions to a source of many different types of video programming using coaxial cable. The cable provider 2(catches, obtains, acquires) coded, or scrambled, programming from a communications satellite, as well as from terrestrial links, including broadcast television stations. The signal may be scrambled to prevent 3(unchecked, uncoded, unpaid) access to the programming. The cable provider electronically unscrambles the signal and supplies the decoded signals by 4(air, signal, cable) to subscribers. Television 5(workers, users, makers) with personal satellite dishes can access satellite programming directly without a cable installation. Personal satellite dishes are also a subscriber service. Fees are paid to the network operator 6(in, out, to) return for access to the satellite channels.

Most television sets outside of the United States that receive programming use different types of standards for receiving video signals. The European Phase Alternative Line standard generates a higher-resolution picture than the sets used in the United States, but these television sets are more expensive. Manufacturers now offer digital video and audio signal processing, which features even higher picture resolution and sound quality. The shape of the television screen is changing as well, reflecting the aspect ratio (ratio of image height to width) used for movie presentation.
