A method for transmitting N-bit digital television representative signals through a transmission path, comprising: organizing said digital signals into recurrent groups of five time-adjacent samples representative of horizontally-adjacent pixels on each one of a plurality of lines of said television

A method for transmitting N-bit digital television representative signals through a transmission path, comprising: organizing said digital signals into recurrent groups of five time-adjacent samples representative of horizontally-adjacent pixels on each one of a plurality of lines of said television representative signal; offsetting each group of samples by two pixel positions from line-to-line; comparing first and second samples of a group of a first one of said lines with a second sample of said group to form first and second difference signals, respectively; comparing a fourth sample of said group with the second sample of a group on a second horizontal line adjacent said first horizontal line to form a third difference signal; comparing a fifth sample of said group with the second sample of a group on a third horizontal line adjacent said first horizontal line to produce a fourth difference signal; representing each of said first, second, third and fourth difference signals by words of M bits, where M is less than N bits; transmitting said first, second, third and fourth difference signals of M bits and said N-bit second signal.
