Which committee developed the basic technical standards used in American TV today?

The National Television System Committee (NTSC) is recognized for developing the basic technical standards that have been employed in American television for decades. Established in the late 1940s, the NTSC played a pivotal role in standardizing broadcasting methods, particularly the analog television system. Their contributions helped define aspects such as frame rates, color transmission, and audio-video synchronization, which collectively laid the groundwork for how television operates in the United States. The standards developed by this committee became widely adopted and were instrumental in shaping the broadcasting landscape, ensuring that equipment manufactured by various companies could work together seamlessly.

In contrast, the other options pertain to different groups or organizations that do not primarily focus on the foundational technical standards for American television. While each may have roles in the broader context of broadcasting, they are not responsible for the establishment of the core technical principles that govern TV technology in the U.S.
