What is an inexpensive device that is used by cable operators to provide digital TV services to all their customers?

• A. A digital terminal adapter or DTA
• B. A DVR
• C. A Set-top box
• D. A cable modem

Answer: (A)

The basic idea is a low-cost receiver that lets customers access digital TV without the higher price tag of a full-featured box. A digital terminal adapter is designed to decode the operator’s digital signals and feed them to a TV, making digital channels available to all customers, including those with older televisions. Because it’s inexpensive, it’s ideal for widespread deployment and basic digital service. In contrast, a DVR is mainly for recording programs, not for delivering the service; a set-top box provides more features and costs more; a cable modem is for internet access, not video.
