NTSC - Wikipedia, the free encyclopedia. Television encoding systems by nation; countries now using the NTSC system are shown in green. NTSC, named after the National Television System Committee. In 1. 95. 3 a second NTSC standard was adopted, which allowed for color television broadcasting which was compatible with the existing stock of black- and- white receivers. NTSC was the first widely adopted broadcast color system and remained dominant until the 2. ATSC, ISDB and others. Most countries using the NTSC standard, as well as those using other analog television standards, have switched to, or are in process of switching to newer digital television standards, there being at least four different standards in use around the world. North America, parts of Central America, and South Korea are adopting or have adopted the ATSC standards, while other countries are adopting or have adopted other standards. After nearly 7. 0 years, the majority of over- the- air NTSC transmissions in the United States ceased on June 1. Digital broadcasting allows higher- resolution television, but digital standard definition television continues to use the frame rate and number of lines of resolution established by the analog NTSC standard. History. In March 1. Radio Manufacturers Association (RMA). Technical advancements of the vestigial side band technique allowed for the opportunity to increase the image resolution. The NTSC selected 5. RCA's 4. 41- scan line standard (already being used by RCA's NBC TV network) and Philco's and Du. Mont's desire to increase the number of scan lines to between 6. Other standards in the final recommendation were an aspect ratio of 4: 3, and frequency modulation (FM) for the sound signal (which was quite new at the time). In January 1. 95. In December 1. 95. NTSC color television standard (later defined as RS- 1. The compatible color standard retained full backward compatibility with existing black- and- white television sets. Color information was added to the black- and- white image by introducing a color subcarrier of precisely 3. MHz (nominally 3. MHz). The precise frequency was chosen so that horizontal line- rate modulation components of the chrominance signal would fall exactly in between the horizontal line- rate modulation components of the luminance signal, thereby enabling the chrominance signal to be filtered out of the luminance signal with minor degradation of the luminance signal. Due to limitations of frequency divider circuits at the time the color standard was promulgated, the color subcarrier frequency was constructed as composite frequency assembled from small integers, in this case 5. These changes amounted to 0. It used a rotating color wheel, reduced the number of scan lines from 5.

Office of Defense Mobilization (ODM) in October, ostensibly due to the Korean War. The first color NTSC television camera was the RCA TK- 4. TK- 4. 0A, introduced in March 1. Later that year, the improved TK- 4. The NTSC standard has been adopted by other countries, including most of the Americas and Japan. With the advent of digital television, analog broadcasts are being phased out. Most US NTSC broadcasters were required by the FCC to shut down their analog transmitters in 2. Low- power stations, Class A stations and translators were required to shut down by 2. Technical details. Each frame is composed of two fields, each consisting of 2. The remainder (the vertical blanking interval) allow for vertical synchronization and retrace. This blanking interval was originally designed to simply blank the receiver's CRT to allow for the simple analog circuits and slow vertical retrace of early TV receivers. However, some of these lines may now contain other data such as closed captioning and vertical interval timecode (VITC). In the complete raster (disregarding half lines due to interlacing) the even- numbered scan lines (every other line that would be even if counted in the video signal, e. For comparison, 5. PAL- B/G and SECAM use 6. The NTSC field refresh frequency in the black- and- white system originally exactly matched the nominal 6. Hz frequency of alternating current power used in the United States. Matching the field refresh rate to the power source avoided intermodulation (also called beating), which produces rolling bars on the screen. When color was added to the system, the refresh frequency was shifted slightly downward to 5. Hz to eliminate stationary dot patterns in the difference frequency between the sound and color carriers, as explained below in . Synchronization of the refresh rate to the power incidentally helped kinescope cameras record early live television broadcasts, as it was very simple to synchronize a film camera to capture one frame of video on each film frame by using the alternating current frequency to set the speed of the synchronous AC motor- drive camera. By the time the frame rate changed to 2. Hz for color, it was nearly as easy to trigger the camera shutter from the video signal itself. The actual figure of 5. In early TV systems, a master voltage- controlled oscillator was run at twice the horizontal line frequency, and this frequency was divided down by the number of lines used (in this case 5. Hz in this case). This frequency was then compared with the 6. Hz power- line frequency and any discrepancy corrected by adjusting the frequency of the master oscillator. For interlaced scanning, an odd number of lines per frame was required in order to make the vertical retrace distance identical for the odd and even fields, which meant the master oscillator frequency had to be divided down by an odd number. At the time, the only practical method of frequency division was the use of a chain of vacuum tubemultivibrators, the overall division ratio being the mathematical product of the division ratios of the chain. Since all the factors of an odd number also have to be odd numbers, it follows that all the dividers in the chain also had to divide by odd numbers, and these had to be relatively small due to the problems of thermal drift with vacuum tube devices. The closest practical sequence to 5. Their low- efficiency phosphors (notably in the Red) were weak and long- persistent, leaving trails after moving objects. Starting in the late 1. As a consequence, the ATSC digital television standard states that for 4. SMPTE . The three color picture signals are divided into Luminance (derived mathematically from the three separate color signals (Red, Green and Blue)) which takes the place of the original monochrome signal and Chrominance which carries only the color information. This process is applied to each color source by its own Colorplexer, thereby allowing a compatible color source to be managed as if it was an ordinary monochrome source. This allows black- and- white receivers to display NTSC color signals by simply ignoring the chrominance signal. Some black- and- white TVs sold in the US after the introduction of color broadcasting in 1. B& W sets did not do this and chrominance could be seen as a 'dot pattern' in highly colored areas of the picture. In NTSC, chrominance is encoded using two color signals known as I (in- phase) and Q (in quadrature) in a process called QAM. The two signals each amplitude modulate 3. MHz carriers which are 9. The result can be viewed as a single sine wave with varying phase relative to a reference carrier and with varying amplitude. The varying phase represents the instantaneous color hue captured by a TV camera, and the amplitude represents the instantaneous color saturation. This 3. 5. 8 MHz subcarrier is then added to the Luminance to form the 'composite color signal' which modulates the video signal carrier just as in monochrome transmission. For a color TV to recover hue information from the color subcarrier, it must have a zero phase reference to replace the previously suppressed carrier. The NTSC signal includes a short sample of this reference signal, known as the colorburst, located on the 'back porch' of each horizontal synchronization pulse. The color burst consists of a minimum of eight cycles of the unmodulated (fixed phase and amplitude) color subcarrier. The TV receiver has a . Combining this reference phase signal derived from the color burst with the chrominance signal's amplitude and phase allows the recovery of the 'I' and 'Q' signals which when combined with the Luminance information allows the reconstruction of a color image on the screen. Color TV has been said to really be colored TV because of the total separation of the brightness part of the picture from the color portion. In CRT televisions, the NTSC signal is turned into three color signals called Red, Green and Blue, each controlling that color electron gun. TV sets with digital circuitry use sampling techniques to process the signals but the end result is the same. For both analog and digital sets processing an analog NTSC signal, the original three color signals (Red, Green and Blue) are transmitted using three discrete signals (Luminance, I and Q) and then recovered as three separate colors and combined as a color image. When a transmitter broadcasts an NTSC signal, it amplitude- modulates a radio- frequency carrier with the NTSC signal just described, while it frequency- modulates a carrier 4. MHz higher with the audio signal. If non- linear distortion happens to the broadcast signal, the 3. MHz color carrier may beat with the sound carrier to produce a dot pattern on the screen. To make the resulting pattern less noticeable, designers adjusted the original 1. Hz scanline rate down by a factor of 1. Hz. This adjustment ensures that the sums and differences of the sound carrier and the color subcarrier and their multiples (i. The 5. 9. 9. 4 rate is derived from the following calculations. Designers chose to make the chrominance subcarrier frequency an n + 0. The original black- and- white standard, with its 1. Hz line frequency and 4.
