Standard s conversion where the Line Rate of the output standard is significantly higher that of the input standard, e. g. 625/50/2:1 to 1250/50/2:1 or 625/50/2:1 to 625/50/1:1.

The process of converting the frequency of a signal to a higher intermediate frequency or to the transmission frequency. Upconversion is performed at the transmission point to prepare the signal for transmission over the satellite link. See also Downconversion and Frequency Conversion.

The term used to describe the conversion of a lower apparent resolution to a higher one. This process increases the number of pixels and/or frame rate and/or scanning format used to represent an image by interpolating existing pixels to create new ones at closer spacing. As an example, Sony TVs with Digital Reality Creation® can upconvert 480i video sources to 960i. Often referred to as "line-doubling."
