Format conversion

Changing the format of television or other moving media images without changing the vertical (frame or field) refresh rate. Starting with 1920 x 1080/50I and converting it to 720 x 576/50I is a format conversion. This only alters the format spatially, changing the vertical and horizontal size which technically is a relatively straightforward task. Note that this may include aspect ratio conversion (ARC) typically to account for the use of 16:9 and 4:3 displays.
