The first geosynchronous communication satellite, Syncom 2, was launched in 1963. It has become very popular at the end of the first decade of the 21st century due to services such as the BBC iPlayer (in and restrained to the United Kingdom) and Hulu (constricted to the United States); go to List of Internet television providers.  Concept Internet television (otherwise known as Internet TV, Catch-up TV or Online TV) is television service distributed via the Internet.

Internet television allows viewers to choose the show or the TV channel they want to watch from a library of shows or from a channel directory. The first satellite television signal was relayed from Europe to the Telstar satellite over North America in 1962. The Hybrid Broadcast Broadband TV (HbbTV) consortium of industry companies (such as SES Astra, Humax, Philips, and ANT Software)is currently promoting and establishing an open European standard (called HbbTV) for hybrid set-top boxes for the reception of broadcast and broadband digital TV and multimedia applications with a single user interface.

The first domestic North American satellite to carry television was Canada’s geostationary Anik 1, which was launched in 1972. In varied areas of the world it provides a wide range of channels and services, often to areas that are not serviced by terrestrial or cable providers. History The world’s first commercial communication satellite, called Intelsat I (nicknamed Early Bird), was launched into synchronous orbit on April 6, 1965. ATS-6, the world’s first experimental educational and Direct Broadcast Satellite, was launched in 1974. Satellite television is television delivered by the process of communications satellite and received by a satellite dish and set-top box.

Satellites used for television signals are generally in either naturally highly elliptical (with inclination of +/-63.4 degrees and orbital period of about 12 hours, also known as Molniya orbit) or geostationary orbit 37,000 km (22,300 miles) above the earth’s equator. Satellite television, like other communications relayed by satellite, starts with a transmitting antenna located at an uplink facility. The first Soviet geostationary satellite to carry Direct-To-Home television, called Ekran, was launched in 1976. Technology The uplink dish is pointed toward a specific satellite and the uplinked signals are transmitted within a specific frequency range, so as to be received by one of the transponders tuned to that frequency range aboard that satellite. Uplink satellite dishes are very large, as much as 9 to 12 meters (30 to 40 feet) in diameter.

The leg of the signal path from the satellite to the receiving Earth station is called the downlink. C-band transmission is susceptible to terrestrial interference while Ku-band transmission is affected by rain (as water is an excellent absorber of microwaves at this particular frequency). A significant satellite has up to 32 transponders for Ku-band and up to 24 for a C-band only satellite, or more for hybrid satellites. The downlinked satellite signal, quite weak after traveling the great distance (visit inverse-square law), is collected by a parabolic receiving dish, which reflects the weak signal to the dish’s focal point. Prototypal transponders each have a bandwidth between 27 MHz and 50 MHz.

This feedhorn is essentially the flared front-end of a section of waveguide that gathers the signals at or near the focal point and ‘conducts’ them to a probe or pickup connected to a low-noise block downconverter or LNB. The evolution of LNBs was one of necessity and invention. The LNB amplifies the relatively weak signals, filters the block of frequencies in which the satellite TV signals are transmitted, and converts the block of frequencies to a lower frequency range in the L-band range. The advantages of using an LNB are that cheaper cable could be used to connect the indoor receiver with the satellite TV dish and LNB, and that the technology for handling the signal at L-Band and UHF was far cheaper than that for handling the signal at C-Band frequencies. Direct broadcast satellite dishes are fitted with an LNBF, which integrates the feedhorn with the LNB.

You also can’t watch two separate programs on two TVs hooked up to the same receiver. News Corporation currently holds a 38% stake, which it is in the process of selling to Liberty Media. The leading satellite television broadcaster in the United Kingdom is a subscription based service named Sky Digital, marketed by British Sky Broadcasting. The provider may occasionally send signals that disrupt illegal de-scramblers, as an electronic counter measure (ECM) against illegal users. In 1996, EchoStar’s Dish Network went online in the United States and has gone on to similar success as DirecTV’s primary competitor.
