A Viewsat Xtreme FTA receiver. A free-to-air or FTA Receiver is a satellite television receiver designed to receive unencrypted broadcasts. Modern decoders are typically compliant with the MPEG-4/DVB-S2 standard and formerly the MPEG-2/DVB-S standard, while older FTA receivers relied on analog satellite transmissions which have declined rapidly in recent years.
The ellipses indicate the necessary antenna diameter for receiving in cm. The footprint of a communications satellite is the ground area that its transponders offer coverage, and determines the satellite dish diameter required to receive each transponder's signal. There is usually a different map for each transponder (or group of transponders ...
Free-to-air (FTA) services are television (TV) and radio services broadcast in unencrypted form, allowing any person with the appropriate receiving equipment to receive the signal and view or listen to the content without requiring a subscription, other ongoing cost, or one-off fee (e.g., pay-per-view).
Universal Satellites Automatic Location System (USALS), also known (unofficially) as DiSEqC 1.3, Go X or Go to XX is a satellite dish motor protocol that automatically creates a list of available satellite positions in a motorised satellite dish setup. It is used in conjunction with the DiSEqC 1.2 protocol.
Satellite television, like other communications relayed by satellite, starts with a transmitting antenna located at an uplink facility. [7] Uplink satellite dishes are very large, as much as 9 to 12 meters (30 to 40 feet) in diameter. [7] The increased diameter results in more accurate aiming and increased signal strength at the satellite. [7]
Coverage maps are designed to indicate the service areas of radiocommunication transmitting stations. Typically these may be produced for radio or television stations, for mobile telephone networks and for satellite networks. For satellite networks, a coverage map is often known as a footprint.
A satellite minidish. This is a list of the free-to-air channels that are currently available via satellite from SES Astra satellites (Astra 2E/2F/2G) at orbital position 28.2 °E, serving Ireland and the United Kingdom. Sky and Freesat use these satellites to deliver their channels. If one was to change providers between Sky and Freesat, one ...
In December 1975, RCA created Satcom 1, the first satellite built especially for use by the then three national television networks (CBS, NBC, and ABC).Later that same year, HBO leased a transponder on Satcom 1 and began transmission of television programs via satellite to cable systems.
