Since television was invented, the stations broadcast analog signals, or continuously varying radio waves. The famous "snow" or ghosting is a problem with this way to send broadcast signals. Another problem is the limited bandwidth for a growing number of TV channels.
After the transition, emissions will only be sent via digital signals, using a series of zeros and ones to transmit data as a computer does. The result is clearer, a more reliable picture and sound, and the possibility options programming more interactive features.
Because of the way to a digital signal transmitted information, has more space for additional data. So now the television networks that once passed through a channel, like channel 3, can now broadcast in several segments of the channel, for example: 3-1, 3-2 3-3, 3-4. Each channel can offer specialized programs for a particular audience.

From January 1, 2008 to March 31, 2009, all households Americans are eligible for a program voucher for the government to offset the cost of $ 40 for up to two boxes per family. A list of eligible boxes are available at the National Telecommunications and Information Administration, which administers the program.
Apart from the purchase of one or join a cable TV converter, you can also choose to buy new loans to the digital input of a TV. After May 2007, all new TVs must be prepared to receive digital signals or be clearly identified as additional equipment required.
