Why is satellite the ideal medium for interactive television (ITV) applications?
Satellite television is the ideal medium for delivery of ITV for the following reasons: A satellite signal can be delivered anywhere, whereas cable is limited in its reach. Satellite can bring interactivity to those living in rural or suburban areas where cable is often not available. ITV applications operate most efficiently with a digital signal and satellite always delivers a 100 percent, crystal-clear digital audio and video signal. Cable has begun to roll-out digital cable, but it currently has limited availability. Furthermore, the quality of a digital signal delivered through cable can be degraded to a certain extent. The quality of a digital signal beamed from a satellite to a dish is not subject to degradation and therefore, is a superior quality signal. Satellite television providers are already beginning to incorporate ITV applications into their products and hardware, whereas current cable ITV applications must typically be added-on to the initial cable system.
