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 interval and suitably one half the sampling interval. Since a TV raster includes an odd number of horizontal lines, a particular line location on the reproduced raster will be formed of samples which shift back and forth at one half the TV frame rate, i.e. 15 cycles per second.
