A scan arrangement supplies real line video pixel information to an input demultiplexer that samples the pixels at a frequency of 4fc (fc=color subcarrier) and sequentially writes the sampled information in a series of line memories at an H (horizontal frequency) rate. A plurality of output multiplexers read information from the line memories at a 2H rate and supply it to a video interpolator where interpolated lines are produced based upon immediately adjacent real lines. The video output is at a 2H rate and consists of alternate real and interpolated lines in two successive fields. A vertical detail enhancement circuit combines pixel data from each set of three successive lines (upper (u), lower (l) and middle (m) lines) in accordance with the formula 2m-(u+1), to develop a vertical detail component.
