ABSTRACT:
Digital data to be communicated are provided with error correcting code. Between consecutive signals representing real, or valid data (pixels in TV transmission) there are interpolated "phantom" data signals so chosen as to maintain the encoded signal within the limited frequency spectrum available for communication. Upon reception, the valid data (pixels) are extracted from the sequence of valid and interpolated data (phantom pixels), thereby reconstituting the original valid data.
