Satellite TV was introduced to the masses in early 1990, and since then has taken off to be one of the most preferred ways of receiving digital entertainment. Since its introduction, many satellite companies have entered the market. One of the most popular in the United States is Dish Network. Though all you need to do is turn on your TV, Dish Network uses a series of high tech equipment to get your favorite television shows into your home.
Dish Network subscribers get their programing from a direct broadcasting satellite, or DBS. In the early introduction of the satellite system, users would have to direct their satellites to specific areas in the sky and then change that direction whenever they wanted to find a different channel. A DBS satellite is like an airline hub for digital broadcasting. The user needs to only direct his home satellite at the Dish Network satellite. He can then receive all the channels that Dish Network offers, without having to redirect his satellite when he wants to change channels.
Dish Network service starts with a programming source. This is where Dish Network gets their programming from. Examples of programming sources would be HBO or CNN. The programming source sends its shows to the Dish Network broadcast center.
Once the programming has reached the Dish Network broadcast center, it prepares the programs for broadcast to its satellite. All programs that come to the broadcast center are in digital format, and are transmitted as such. Digital format provides a clearer picture and sharper sound than other past television formats. The signal is also specially coded so that only Dish Network customers can receive the programming.
The next stop for the programming is to be transmitted from the broadcasting center to the Dish Network satellite. This satellite is a special piece of equipment that has been placed in orbit in the space surrounding earth. The satellite has the ability to intercept broadcast signals and direct them down to multiple targets, or in Dish Network's case, subscriber homes across the nation.
Once the programming reaches the Dish Network satellite, it is reflected to the homes of the different Dish Network subscribers. A subscriber grabs the signal by using a small home satellite dish. As long as the dish is pointed towards the right area of the sky, the dish can pick up the signal and carry it into the subscriber's home.
Once the satellite signal has been received, the signal must be decoded to be seen on a standard television set. This process is done by the Dish Network receiver. The receiver also separates the signal into channels, allowing a user to surf between the different programming options provided by Dish Network.
