A television broadcasting satellite Satellite television is television programming delivered by the means of communications satellite and received by an outdoor antenna, usually a parabolic mirror generally referred to as a satellite dish, and as far as household usage is concerned, a satellite receiver either in the form of an external set-top box or a satellite tuner module built into a TV set. Satellite TV tuners are also available as a card or a USB flash drive stick to be attached to a personal computer. In many areas of the world satellite television provides a wide range of channels and services, often to areas that are not serviced by terrestrial or cable providers. A space TV satellite Broadcast satellite television comes to the general public in two distinct flavors - analog and digital. This necessitates either having an analog satellite receiver or a digital satellite receiver.

Not sure what planet you live on....but.. Satellite TV by definition has always been "digital". Never analog. Only "cable" services still broadcast signals in analog mode. N. American Broadcast TV stations were mandated to convert to all digital mode in 2008, and only very low power "local" TV stations are permitted to send analog signals even though there are very few analog receivers left to receive such signals. Amateur Radio stations have been sending/receiving satellite based TV over the AMSAT satellites for over 30 years on their specified worldwide frequencies.
