Digital TV can be contrasted to the more traditional in the past , analog TV , where signals were being sent via radio transmission and are now in digital format , catering for audio and video together.
This form of TV is now commonplace after the much-publicised ‘switch-over’ you would have heard about and we all enjoy this media daily.
The arguments for doing this were wide-ranging but the use of modern communication means we have quicker, faster and clearer broadcasts to view from the providers.
Rather than using the old TV Aerials , most of us are receiving digital TV via cable and satellite , with set-top receivers being required in many cases to ensure viewers have a reception. In the past , one would often struggle to obtain a clear TV reception from various forms of antennae , often leading to several different aerials being located next to chimneys and along rooftops.
The TV Aerial Fitter has been transformed in most case to the Satellite and Cable Engineer , with largely the same lofty role with the former , whilst cable is still not available in many areas , despite a purposeful drive in the past and continuing in many towns and cities.
