How to convert between different video standards?
Different video standards are used in different countries. Most European countries use PAL, NTSC is used in the US, Japan and some others and SECAM is used mainly in France, and in a few other countries. Each standard uses different color encoding schemes. The most common way to convert between the standards is to use a Standards Converter. It is made of a Multistandard color decoder, which separates video into its components, usually to a digital form, with frame buffers (for converting between PAL and NTSC – as the timing of those standards differ). The final stage uses a digital encoder, for receiving component video, which is “standard-less” at this point, at least color-wise, and converting the components to Composite Video or Y/C in the required standard.
