What is the difference between NTSC and PAL?
NTSC stands for National Television system committee and is the video system or standard broadcast format used in North America and most of South America.
The NTSC broadcasting system is designed to output 60 fields for each second, and the electrical power outage in the United States is created at 60 hertz, most TV’s utilize an intertwined framework where the NTSC can alternate 30 lines of imagery tailed by a further 30 interchanging lines- causing 30 frames of comprehensive and complete imagery per second.
PAL (Phase Alternating Line) is the standard broadcast format mostly used overseas in Europe and Asia where the electrical power is generated at 50 hertz. Televisions that use PAL as the broadcast format only produce 25 frames per second. To watch a PAL movie on an NTSC television while retaining the integrity of the content, you must add five framers per second.
The impact of PAL results in lower frames per each second the benefits are a much higher resolution, the NTSC facilitates 100 less lines than PAL, and when attempting to transfigure motion picture to PAL, the reduced screen must be considered, and black bars are almost certainly included resulting in a widescreen effect.
What is the standards conversion?
Converting between video standards is a complex process involving conversion between a different number of pixels and different frame rates. For example, PAL is 625 lines at 50 fields/sec and NTSC is 525 lines at 60 fields/sec. The line count is different by 100 lines as well as the 10 fields/sec difference.
To effectively make the conversion from PAL to NTSC, a supplementary 10 frames per second are required and are created in real time, the convertor generates additional frames from the existing frames.
Television contains numerous concealed signals which do not all transfer within the conversion process from one standard to the other, amongst the concealed signals sits Closed Captioning, to maintain clean cut image quality and to make sure they stay complete, we initiate two closed caption masters, 720 and 1080i.
