NTSC

An acronym for the National Television Standard Committee. It is the television standard for North America and some countries in South America, which owns 525 Hz líneas/60, two fields per table and thirty frames per second. Also used in the Caribbean, South Korea, Japan and South America. A 30 fps signal with 525 lines of resolution of which 480 to 483 are viewable. Transmitted via a 6MHz channel. It is the oldest standard and with lower resolution of the most used system in the world 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). There are several other standards used throughout the world, most notably the PAL system so ensure compatibility if you travel with your kit internationally.

It is an acronym for National Television System Committee (National Television Systems), which established our standard analog TV American 525-line about 60 years ago. Although it is called a standard of "525 lines," we can only see 480 lines on a TV screen. The ATSC digital transmission will eventually replace the ATSC NTSC.

Rabbit ear antennas are not as common as they used to be, but there still may be a few folks out there using over-the-air broadcasts as their primary television source. If you are currently getting good reception on your small screen TV, you will get decent results with your front projector. This is not the optimum arrangement, however. Those imperfections you see as reception fades are only amplified on the large screen.
