Abstract
A method for scrambling a television signal for use with a multiplexed analog component (MAC) format employs a three digital bit code for each horizontal line of the picture. The bits identify the position of the luminance and chrominance information of the signal for every line of the television picture and whether the information is to be scanned from left to right or right to left.
