The first encryption methods used for big-dish satellite systems used a hybrid approach; analogue video and digital encrypted audio. This approach was somewhat more secure, but not completely free of problems due to piracy of video signals. Digital TV services, by nature can more easily implement encryption technologies.
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.
2-way DiSEqC switch 4-way DiSEqC switch with attached coaxial cables.. DiSEqC (/ ˈ d aɪ s ɛ k, d aɪ ˈ s ɛ k s i /; [citation needed] short for Digital Satellite Equipment Control) is a special communication protocol for use between a satellite receiver and a device such as a multi-dish switch or a small [1] dish antenna rotor.
DirecTV has about 12.4 million customers, but in recent years, like other pay-TV providers, it has seen its numbers dwindle in the face of competition from streaming networks
A Shaw Direct 45x60cm dish, with new triple satellite LNB compatible with Anik F1, Anik F2 and Anik G1. The system requires an elliptical antenna of at least 45x60cm in size with a special LNB pair built as one unit to accommodate the narrow 3.8° spacing between satellites; the receiver uses the Motorola-proprietary Digicipher II system which has so far been virtually free of the problems ...
The relatively strong K u band transmissions allowed the use of dishes as small as 90 cm for the first time. [8] On 4 March 1996, EchoStar introduced Digital Sky Highway (Dish Network). [9] This was the first widely used direct-broadcast satellite television system and allowed dishes as small as 20 inches (51 cm) to be used.
Canada had a similar analog TV termination date set to September 1, 2011 (except in some remote northern regions). [citation needed] It was feared that the US switch-off would cause millions of non-cable- and non-satellite-connected TV sets to "go dark". Viewers who did not upgrade, either to a television with a digital tuner or a set-top box ...
It is possible to also get a bad picture if the signal strength of the TV transmitter is too high. An attenuator inserted in the antenna lead-in wire may be used if the television receiver displays signs of overload in the RF front end. Strong out-of-band signals may also affect television reception and may require band-pass filters to reduce ...
