A Digital to Analog Converter Box or Digital Television (DTV) Converter Box is an electronic device that converts the new free over-the-air digital signal into an analog signal viewable on an older “analog” television set.
A digital-to-analog converter box will not give you a digital picture on an analog TV set but will not convert your analog TV set into a high-definition TV, also known as an HDTV.
A TV converter box is a stand-alone device that allows your antenna to receive and convert digital signals into a format analog television set can display. A DTV converter box hooks up to your analog television set and over-the-air antenna.
The box converts the digital television signal into an analog format, making it viewable on your analog TV set. Several of these devices have already been shown and, while few were initially available, they are becoming more available by the day.
