NTSC 
National Television Systems Committee 
This body was established by the Federal Communications Commission (FCC) to set television and video standards in the United States. (The predominant standards outside the United States are PAL and SECAM.) The acronym refers to the television broadcast standard, which specifies 525 lines of resolution per second for broadcasts, and it combines blue, red, and green signals with an FM frequency for audio. NTSC should eventually be succeeded by HDTV (high-definition TV).
