What type of transmission is indicated by the term "NTSC"?

• A. A digital audio signal
• B. An analog fast-scan color TV signal
• C. A satellite communication signal
• D. A video streaming protocol

Answer: (B)

The term "NTSC" refers to the National Television System Committee, which developed a standard for analog television broadcasting in North America. Specifically, NTSC is associated with a color television transmission system used primarily for standard definition television signals. This system was widely used in the United States and other countries until the transition to digital broadcasting.

In the context of the choices provided, selecting the option related to an analog fast-scan color TV signal accurately reflects the nature of NTSC. It captures the essence of how television technology operated for many years before the shift to digital formats. The other options do not accurately describe NTSC or its usage, as they pertain to different technologies or formats that are distinct from the analog television standard established by NTSC.
