Why is the TV broadcasting standard switching from analog to digital?
Everyone who is involved in the switch from analog to digital television will benefit from the transition. Consumers will profit from an improvement in picture and sound quality. Digital transmissions are more efficient than analog, which allows for additional channels to be offered. Through multicasting, broadcasters can deliver a high definition (HD) digital program as well as multiple standard definition (SD) digital programs at the same time. Because DTV frees up parts of the broadcast spectrum, these unused portions can be used for other purposes, such as public-safety communication systems for police and fire departments. The government will also auction some of the spectrum to companies so that they can provide advanced wireless services to consumers, such as wireless broadband.
