The TV Dish Network Delivers Your Favorite Programs From Satellites Directly To You
In 1950 television was still in its infancy. Although TV was actually first broadcast in the late 1920s, development of commercial broadcasting was interrupted by the Great Depression and World War II. No one during that time of vacuum tubes and 7″ screens really thought about worldwide television communications. Then, the former Soviet Union launched the first Sputnik in 1957, shaking up the world and launching the space race. The first signals were bounced off a Telstar satellite from Europe to North America in 1962, and TV dish network broadcasting was on its way.
As early as the late 1960s both the Soviet Union and the United States had broadcast television from space. The type of commercial programming we watch today did not become widely available until the late 1990s. Before that time subscribers could receive satellite TV, but only through giant antennas. These massive structures were difficult to hide, and got their name because they resembled huge tilted metal mesh bowls which often overshadowed the adjacent buildings. They were hard to manage, and users wanting to change channels had to constantly adjust them.
Some of these early dishes were several meters across, in contrast to the discreet antennas we see today. Usually measuring about 18-20″ in diameter, they can be installed on an apartment balcony or the side of a building. They put satellite television in the realm of practical everyday use, and today there are over 13 million subscribers. Programming on a dish service is nearly identical to that of cable TV, and unlike cable, can serve remote locations.
This technology is really a modern wonder that most of us take for granted. Today’s geosynchronous, or fixed position satellites are operated and maintained by the Echostar Corporation, while the ground installation and subscription services are handled by other companies. They and others like them are able to cover a large portion of the world’s land surface. Most nations have access to some form of orbiting broadcasts unless there are economic or political considerations prohibiting it.
Although similar to cable service in content, there are big differences in how the signals are sent and received. Dish programming originates on the ground, where it is prepared for uplink. All transmission is digital, and encoded to prevent signal theft. The orbiting device then gathers those signals and rebroadcasts them directly to individual home antennas.
Back on earth the broadcast is captured by small metal disc antennas, which feed into a receiver. Satellite receivers are about the same size as cable boxes or stereo amplifiers, and can decode the signals into digital or analog formats. As long as there is a clear sky view, the antenna needs no constant adjustment. In the earlier days, those with digital television sets needed two receivers, but this is no longer the case.
There are advantages to this system. The content is virtually the same as cable, and can cost less. Users can choose self-installation, which saves on startup costs. In the past a big problem was the inability to receive local programming without an over-the-air antenna, but this is no longer the case. The small curved antennas are more attractive than those big rooftop models of the sixties, and using these devices is no more complicated than turning them on. For people seeking a choice in television providers, a TV dish network is an excellent alternative.
