Raleigh, N.C. — WRAL-TV took part in a statewide test Wednesday night designed to help viewers figure out if they are ready for the digital TV transition.

By law, on Feb. 17, 2009, full-power television stations nationwide will stop using the old method of transmitting TV signals, known as analog, and begin broadcasting exclusively in a digital format.

Last week, Wilmington became the first television market in the country to begin digital-only broadcasting.

Some people there had trouble with their converter boxes because they weren't programmed to the station's correct digital channel. For example, they were set on Channel 5 instead of 5.1.

Wednesday night, the rest of North Carolina took part in a short test designed to help viewers determine if they are ready.

People watching WRAL’s News at 6 found out if they need to make adjustments.

Those watching a TV that receives a digital signal were able to see the newscast. However, those who only receive an analog signal saw a message letting them know their TV set is not digital ready.

The transition is being compared to the change from black-and-white television to color TV in the 1950s. TV stations have relied on analog signals for 65 years; digital TV provides a much sharper picture and better sound.
