H04N1/413 - CPC Classification

Classification description:

Scanning, transmission or reproduction of documents or the like, e.g. facsimile transmission; Details thereof; Bandwidth or redundancy reduction for the transmission or storage or reproduction of two-tone pictures, e.g. black and white pictures Systems or arrangements allowing the picture to be reproduced without loss or modification of picture-information

Sub-classes:

H04N1/4135 » {in which a baseband signal showing more than two values or a continuously varying baseband signal is transmitted or recorded} 0
H04N1/415 » in which the picture-elements are subdivided or grouped into fixed one-dimensional or two-dimensional blocks 36
H04N1/417 » using predictive or differential encoding 20
H04N1/419 » in which encoding of the length of a succession of picture-elements of the same value along a scanning line is the only encoding step 9
