A method and apparatus for suppressing from transmission, non-informational data words from a source of data words such as a video camera. Data words having values greater than a predetermined threshold are transmitted whereas data words having values less than a predetermined threshold are not transmitted but their occurrences instead are counted. Before being transmitted, the count of occurrences of invalid data words and valid data words are appended with flag digits which a receiving system decodes. The original data stream is fully reconstructable from the stream of valid data words and count of invalid data words.
