Digital TV Key Terms

Get up to speed with the wave of digital television
By Emily Lugg Beginning on June 12, 2009, all television stations in the U.S. will be required to institute the transition from an analog signal to a digital one. Along with the switch comes a new set of terms that encompasses everything from the signal itself to the new equipment you'll need to get up to speed. The digital wave allows television stations to produce more effective broadcasts as well as offer more programming options along with a clearer picture and sound quality.

Digital TV converter

The converter prevents analog users from having to purchase a new television and allows them to adapt their current television equipment to receive digital signals.
