Have you ever wondered why some homes have satellite dishes installed onto their roofs? Wonder no more, as these are only digital satellite systems. These are merely large sized versions of your television antenna or your wireless internet receivers. Most of the time, these satellite dishes or digital satellite systems are used to provide quality entertainment in your homes. It serves a purpose similar to cable television. The only difference is that the data is received through the satellite dish and in digital format.
First you need to be a subscriber to the satellite service providers. They will supply you with the dish and the decoder. The dish is for you to get a signal from one of the satellites present in space. Of course the provider will most likely align you to a satellite that provides the service you bought from them, like television channels or Internet service. Of course digital satellite systems will need to have that dish set-up on your home then connected to your entertainment system. As for the decoder, it is just a precautionary measure used by your service provider. Whatever digital data you actually receive are encoded in a specific way depending on your service provider. So a decoder is used to prevent other people from utilizing the service that only you should have to access.
Digital satellite systems have a wider range in terms of entertainment function and information. If your digital satellite system is for television channels, this should mean you have a lot of channels to choose from. Digital satellite systems even have digital guides so you can see when a show will be aired, its brief description, and sometimes even the actors on the show.
Digital satellite systems have some advantages and disadvantages. Aside from its wide coverage, the channels and the shows are not regulated by the government. An advantage to this is that the price for the service is generally cheaper than that of cable television.
One disadvantage of digital satellite systems is that the data you receive and transmit is not that secure. The data is free to pass from your home to the satellite and vice-versa. This will only be a threat if you are using it like that of an oversized wireless broadband device. Some providers say that the data is secure. It may be encoded which is a indication that the data can be decoded as well. Since there are only limited regulations for the technology, security is really no that high. It is still best to use the digital satellite systems for home entertainment purposes only.
