Which standard corresponds to the North American broadcast system, with approximately 59.94 fields per second at 29.97 frames per second?

Explanation:
North American broadcast uses the NTSC system. It is interlaced, so each frame is made from two fields, giving about 59.94 fields per second for a 29.97 frames per second rate. The slight 0.03 fps adjustment from 30 to 29.97 was made to keep color encoding in sync with the system and the power grid. PAL, by contrast, runs at 25 frames per second (50 fields per second), and the remaining terms refer to software or interchange formats rather than broadcast standards.
