Most people know that a signal is relayed from the main distribution center up to the satellite and then bounced back to the dish on your roof in order to deliver TV to your home.
However, not many people actually know how a satellite works and what is involved in creating a network of satellites that can provide coverage to an entire country, or many different countries.
Here, we'll explore a bit of the behind the scenes work that occurs while delivering satellite television to your home.
Up In Space
By definition, a satellite is anything that orbits the Earth in a circular or elliptical path. The Moon is, by this definition, a satellite of the Earth. The Earth, as well, is actually a satellite of the Sun.
As far as modern technology is concerned, a satellite is a piece of equipment that orbits the Earth and performs a certain function.
Satellites are not factory-produced, one size-fits all. Each is specifically designed to perform a certain task, and this makes for a lot of variety. Some satellites form triangulation for GPS purposes, others are used to track weather patters, and some have very specific scientific objectives.
For example, the Hubble Space Telescope is a satellite affixed with an array of lenses and photography equipment that is used to take pictures of space without the atmospheric interference experienced at land-based observatories.
For the purpose of this article however, the satellites in which we are most interested are communication satellites.
Communications Satellites
Inside communications satellites are a number of important systems. For satellite TV customers, it is vital that the satellite stay in a geosynchronous orbit, meaning that it is in the same patch of sky at all times, so the satellite has guidance systems built in to maintain position.
The transponder is, however, the most important component of the equipment. A transponder is a device that receives a signal at one frequency and then retransmits it at another frequency to avoid any interference with the source signal.
Inside each communications satellite are thousands of transponders. The TV provider's transmission center will emit a signal straight to the satellite. The satellite's transponders will analyze that signal and then retransmit it on a different frequency.
The satellite dish mounted on your roof is designed to pick up signals on that frequency and acts like an antenna. The signal then travels to the set-top receiver box, where it is decoded and you can watch your favorite programming.
Satellite Tv On Line
If you are not familiar with the Digital Video Recorder or TiVo unit then you have the only good excuse for not already owning them! First of all, the TiVo and Digital Video Recorder (referred to as the DVR) come free with the package of free satellite equipment that are installed with DirecTV�s free professional installation. So before we get into the awesome features of TiVo and the DVR you already know that you won�t be spending anything extra to get these! The TiVo and DVR units work together so that you can view television in a whole new way. One amazing feature of the combination is the ability to pause and rewind live television. It may sound impossible, although once you understand how it is done it makes perfect sense. The DVR and TiVo units, you get from DirecTV, actually save all of the shows and programs, that play on your channels, temporarily on the DVR as the shows and programs are being aired. This way, in a sense, you are pausing or rewinding a recorded program much like you would using a VCR. One additional bonus with this system is the ability to fast forward through the already recorded programs. Basically, the way that it is set up, whenever you pause live television you are, in a sense, saving up time for when the next commercial break comes on. As your television is paused, live television keeps airing of course, and as live television keeps going your TiVo and DVR keep recording (even when the program you are watching is paused). The result is that you can fast forward from the point you paused it all the way up until you reach the point of the program that is being aired live. That way, every time you get up to go the restroom or get up to get a snack or drink you are saving up fast forward time for commercial breaks. Add up all of that paused time and that is how much time in commercial breaks that you can fast forward through.
DirecTV not only offers the TiVo and DVR unit, they offer the TiVo and DVR units for free when you sign up! Actually DirecTV offers a lot of great features and deals to those who sign up for a monthly package. For instance, DirecTV offers all of the necessary equipment such as the satellite dish, and a Hughes satellite receiver, as well as the luxury equipment such as the TiVo and DVR for free with certain packages. DirecTV also requires no start up fee whatsoever and with the free equipment they offer a 100% free professional installation. To top it all off, DirecTV extends the free equipment and professional installation to free equipment and installation in up to four rooms in your home. What makes this value so amazing is that DirecTV has programming packages with monthly rates comparable to cable monthly rates. Considering DirecTV�s other awesome features like parental controls, and of course their fantastic and well renowned customer service, you really can not go wrong with DirecTV.
