Pixels on computer monitors are often square, but pixels used in electronic video often have non-sq. component ratios, such as those Employed in the PAL and NTSC variants of the CCIR 601 electronic video typical plus the corresponding anamorphic widescreen formats.

Video may be interlaced or progressive. In progressive scan systems, Each individual refresh interval updates all scan lines in Each individual frame in sequence.
