  NTSC - Encyclopedia, History, Geography and Biography
NTSC is the analog television system in use in Canada, Japan, South Korea, the United States, and some other countries, mostly in the Americas (see map).
The NTSC compromised between RCA's desire to keep a 441-line standard (their NBC TV network was already using it) and Philco's desire to increase it to between 605 and 800, settling on a 525-line transmission.
Other technical standards in the final recommendation were a frame rate (image rate) of 30 frames per second consisting of 2 interlaced fields per frame (2:1 interlacing) at 262½ lines per field or 60 fields per second along with an aspect ratio of 4 by 3, and frequency modulation for the sound signal.

NTSC is the analog television system in use in Canada, Japan, South Korea, the Philippines, the United States, and some other countries, mostly in the Americas (see map).
Other technical standards in the final recommendation were a frame rate (image rate) of 30 frames per second consisting of 2 interlaced fields per frame (2:1 interlacing) at 262½ lines per field or 60 fields per second along with an aspect ratio of 4:3, and frequency modulation for the sound signal.
So the NTSC signal includes a short sample of this reference signal, known as the color burst, located on the 'back porch' of each horizontal line, the time between the end of the horizontal synchronization pulse and of the blanking pulse on each line.

 PAL & NTSC & SECAM @ Filmbug
The NTSC format consists of 29.97 interlaced frames of video a second, each consisting of 480 lines of vertical resolution out of a total of 525 (the rest are used for sync, vertical retrace, and other data such as captioning).
NTSC interlaces its scanlines, drawing odd-numbered scanlines in odd-numbered fields and even-numbered scanlines in even-numbered fields, which gives a nearly flicker-free image at approximately 59.94 hertz (nominally 60 Hz / 1.001) refresh frequency, which is close to the nominal 60 Hz alternating current power used in the United States.
For color, NTSC includes a chrominance subcarrier, whose frequency is not a multiple of the horizontal scan frequency and therefore must be kept synchronized by transmitting a colorburst signal on the front porch (an otherwise unused period after the horizontal sync pulse and before the line of video starts).

 National Television System Committee (NTSC)
It took the efforts of the NTSC to recognize that this was a form of a subcarrier modulation process.
On February 2, 1953 the second NTSC color standard was published: CPA was abandoned because of edge flicker effects, the color subcarrier was lowered to 3.579545 MHz, the pedestal on the reference burst was dropped, and the wideband orange-cyan I axis, and narrow-band Q axis modulation scheme suggested by RCA was adopted.
The NTSC forwarded this standard to the FCC in a petition on July 22, 1953.

 Section 1: Color Television Fundamentals (NTSC)
Prior to NTSC standard and the first RCA model that used that standard, there were a small number of other manufacturers that developed color television designs, some of which were produced in tiny quantities, with one design selling only one receiver.
The NTSC system is scheduled to be withdrawn from broadcast use in the United States as early as the end of 2006 (although deployment percentages must be met for the plan to go into effect), to be replaced with a digitally-encoded broadcast system.
In the analog NTSC color television receiver, a lot of complexity is there just to receive the I and Q signals from the broadcast signal, and that circuitry has a critical need to maintain a tight synchronization to the timing of the transmitted color signals.

 NTSC - The TV IV
NTSC is encoded in the YUV color space, which provides a mathematical equivalent of red, green and blue.
When NTSC is broadcast over VHF or UHF, a radio frequency carrier is amplitude modulated by the NTSC signal, while an audio signal is transmitted by frequency modulating a carrier 4.5 MHz higher.
There is no question the NTSC system reflects the limitations and technology of a bygone era; indeed, its compatibility with even the crudest equipment since the dawn of television has been the key to its longevity over seven decades.

 Building Bridges Between The Standards
The third approach is that of standards conversion where the TV signal is actually converted from being a standard signal in one TV system to being a standard signal in another.
Since PAL and NTSC are not that different in the way they encode colour signals, it's not actually that difficult to modify the signal to achieve a reasonable colour reproduction at the same time.
Standards Conversion is the most complex, technically difficult and degrading of all of the techniques for building bridges between TV standards.

 Television Standards - PAL to NTSC - DVDs and MPEG-2
In former times the values 30 Hz/60 Hz were quite correct, but with the implementation of the color television the NTSC refresh rates were lowered from 60 Hz to 59.94 Hz and from 30 Hz to 29.97 Hz for preventing audio flutter during broadcast.
The reason why the NTSC refresh rate was changed by implementation of color television is explained by Bob Myers in a detailed article.
On NTSC the additionally inserted fields are removed by IVTC whereby 59.94 fields/s or 29.97 fps respectively are transformed again to 23.976 fps.

 HDTV Television - An Introduction   (Site not responding. Last check: 2007-10-11)
An important and critical consideration is whether the new HDTV standard should be compatible with the existing color TV standards, supplant the existing standards, or be simultaneously broadcast with the existing standards (with the understanding that the existing standards would be faded out over time).
In 1987, the FCC issued a ruling indicating that the HDTV standards to be issued would be compatible with existing NTSC service, and would be confined to the existing VHF and UHF frequency bands.
The 1990 decision is a radical and non-conservative approach -- one which basically removes the requirement for compatibility by allowing different HDTV and NTSC standards to exist simultaneously for a period of years.

 Macworld: Secrets: Send video abroad
The North American NTSC standard runs at 29.97 frames per second and has a visible resolution of 720 by 480 pixels for DV (720 by 486 pixels for uncompressed signals, such as Digital Betacam).
The traditional method converts 25-fps PAL video to 29.97-fps NTSC video by creating new frames based on the pixel information in the existing frames (this is essentially the reverse of the NTSC-to-PAL process).
To convert PAL to NTSC using the traditional method, follow the same process as for converting NTSC to PAL, but with one important change: choose Advanced Format Conversions: DV NTSC from the Settings pull-down menu.
