James T Russell: Method and apparatus for sampling and reproducing television information. Eli S Jacobs, Klarquist Sparkman Campbell Leigh Hall & Whinston, January 10, 1978: US04068265 (101 worldwide citation)

The effective resolution of a TV presentation reproduced from digitally encoded samples is improved by shifting the sampling points back and forth at a relatively rapid rate. Alternate lines of the original television raster are sampled at shifted points, wherein the shift is less than the sampling ...
