Error Processing Technique for Modified Read Code.
DEPARTMENT OF THE ARMY WASHINGTON DC
Pagination or Media Count:
A method of error processing is disclosed in which the first erroneous line detected in a facsimile transmission is decoded, and printed in the normal manner, up to the point in the line where an error is detected. An erroneous portion of the line is then defined to be the point in the line from which the error is detected as well as four color changes to the left. This erroneous portion is replaced by the corresponding picture elements in the immediately proceding line. The resulting corrected line is then used as a new previous line and the process is repeated with the erroneous portion of each subsequent line being replaced with white until a full line is properly decoded.
