Why are TV stations switching to all-digital?
All-digital it a much better way of transmitting a TV signal. You no longer have to deal with a fuzzy picture or distorted sound. With analog broadcast the further you are away from the TV station’s antenna, the worse your picture will be. With digital broadcast, you get a perfect signal or no signal at all.
In addition, the switch to all-digital broadcasting will free up parts of the broadcast spectrum for public safety communications. Some of the spectrum will be auctioned to wireless companies for the provision of advanced commercial wireless services (such as wireless broadband).
The new technology also allows more options for consumers than the outdated analog system. Broadcasters will be able to provide a super sharp “high definition” (HD) program or multiple “standard definition” (SD) digital programs at the same time. Providing several simultaneous programs on one broadcast channel is called multicasting. This means more choices of free programming for viewers.
