What is "NTSC" format?

The NTSC (National Television System Committee) is a standard format adopted by the FCC for television broadcasts in the United States, Japan, Canada, and Mexico. This is commonly referred to as composite video because of the convergence of luminance and color into a single analog signal:

*525 lines of resolution per frame at 30 frames per second

*60 Hz field frequency

*Requires a 6MHz analog channel for transmission
