How Satellite HD Works

The average consumer needs to know how satellite HD works before purchasing packages from Dish Network and other providers. This form of high definition programming blends two new technologies to bring TV shows with vibrant colors into American homes. An understanding of how these high-definition programs work helps homeowners make informed decisions when purchasing sets and Dish Network systems.

Learn How Satellite HD Works

The first step in the satellite HD process is a data stream running from various networks through the provider. TV networks like ESPN, BBC and Telemundo have individual streams that are bundled together into specific packages. These packages include the Top 100, Top 250 and Multi-Sport offerings provided by Dish Network. Each bundle of digital streams is compressed and sent to orbiting satellites before bouncing down to subscribers.

There are three steps between reception of compressed digital streams and images using uncompressed HD images facilitated by the rented receiver. Each receiver decrypts signals based on codes provided by the program provider. These encryptions are designed to protect signals from hijackers looking for free HD programming.

The receiver decompresses each signal before feeding program streams into a HDTV set. The high-density signal required for high-definition programs makes compression necessary from content producers to satellites. TV sets connected to satellite HD receivers distribute audio and video elements in an interlaced or progressive manner depending on TV model.
