More people are choosing dish satellite service due to the number of channels offered. With the advent of HD, people are wondering how much cost will be involved to upgrade equipment to receive this type of signal.
All dish satellites work the same. Radio signals are transmitted to a satellite in space, which then bounces the signal back to Earth. A small satellite dish receives the signal and sends it into a receiver. The receiver decodes the signal, allowing the television to work.
HD stands for high definition. The digital signal offers a higher resolution so pictures are clearer and sharper. Since this technology is still new, most networks offer few programs in HD.
You must have an HD receiver as well as an HD television to receive any program in HD. A different satellite is not necessary to receive an HD signal.
HD has a much higher picture quality than a regular signal. This is because high definition offers 720 to 1020 lines of resolution to the 525 lines used by regular analog television sets.
Regular satellite television costs subscribers a monthly fee. To receive HD programming, the receiver adds about 50 percent extra a month to the satellite TV bill.
