Television standards conversion

Television standards conversion is the process of changing one type of TV system to another. The most common is from NTSC to PAL or the other way around. This is done so TV programs in one nation may be viewed in a nation with a different standard. The TV video is fed through a video standards converter that changes the video to a different video system.Converting between a different numbers of pixels and different frame rates in video pictures is a complex technical problem. However, the international exchange of TV programming makes standards conversion necessary and in many cases mandatory. Vastly different TV systems emerged for political and technical reasons – and it is only luck that makes video programming from one nation compatible with another.
