These systems specify the standards of television transmission used. For example, India has adopted the PAL television system. Hence, all television transmission in India would follow the PAL standards.

There are three standards for transmitting video. They are defined by the method of encoding color onto a monochrome signal. The methods are defined as:. NTSC supports color television transmission in a 6 MHz channel bandwidth and has interlaced scan lines. Two fields are interlaced to make one frame with a frame rate of

There are three standards for transmitting video. They are defined by the method of encoding color onto a monochrome signal. The methods are defined as:. NTSC supports color television transmission in a 6 MHz channel bandwidth and has interlaced scan lines. Two fields are interlaced to make one frame with a frame rate of The aspect ratio, or ratio of picture width to picture height, is In PAL, however, the color difference signals alternate phase at the horizontal line rate.

PAL video consists of a line frame, a frame rate of 25 Hz, and a field rate of 50 Hz. The aspect ratio is SECAM is a color television broadcasting system using picture lines and a hertz Hz field rate, in which the two color-difference signals are transmitted sequentially instead of simultaneously. Use the information in Table C-1 , Table C-2 , and Table C-3 to compare analog television standards used around the world.

Worldwide Color Television — Standards Similarities and Differences Abstract: Broadly speaking, the fundamental picture performance of a motion picture system in one location in the world is generally the same as in any other location. Thus, international exchange of film programming is comparatively straightforward. Not so in the case of broadcast color television systems. The lack of compatibility has its origins in communications channel allocations and techniques, differences in power source characteristics, network requirements, pickup and display technology, and political considerations relating to international telecommunication agreements.

During the early days of TV, a number of standards came about that governs how the information is to be transmitted from the studio, to the homes of the viewers. The refresh rate is the number of times the image on the screen changes to simulate the illusion of motion. NTSC thus has more fluid motion because of the 10 more frames per second. Consequently, NTSC only uses with only of them visible. The rest are used as control mechanisms for synchronization and vertical retrace.

What is the difference between PAL NTSC and SECAM

Filmbug Top Movie Dictionary Browse.. The name "Phase Alternating Line" describes the way that part of the colour information on the video signal is reversed in phase with each line, which automatically corrects phase errors in the transmission of the signal. NTSC receivers have a tint or hue control to perform the correction manually.

In the s, the Western European countries began plans to introduce colour television, and were faced with the problem that the NTSC standard demonstrated several weaknesses, including colour tone shifting under poor transmission conditions, which became a major issue considering Europe's geographical and weather-related particularities. The goal was to provide a colour TV standard for the European picture frequency of 50 fields per second 50 hertz , and finding a way to eliminate the problems with NTSC. When asked why the system was named "PAL" and not "Bruch" the inventor answered that a "Bruch system" would probably not have sold very well "Bruch" is the German word for "breakage". The first broadcasts began in the United Kingdom in July , followed by West Germany later that year. Telefunken was later bought by the French electronics manufacturer Thomson. Y comprises the monochrome luminance signal, with the three RGB colour channels mixed down onto two, U and V. Like NTSC, PAL uses a quadrature amplitude modulated subcarrier carrying the chrominance information added to the luminance video signal to form a composite video baseband signal.


NTSC uses a refresh rate of 60Hz while PAL and SECAM both use a refresh rate of 50Hz. PAL and SECAM both have a higher resolution by using more lines per frame. Out of the lines of PAL and SECAM, are visible and the rest are used for control as well.
