H04N1/417 - 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 using predictive or differential encoding

Sub-classes:

H04N1/4172 » {Progressive encoding, i.e. by decomposition into high and low resolution components} 13
H04N1/4175 » {involving the encoding of tone transitions with respect to tone transitions in a reference line} 4
H04N1/4177 » {encoding document change data, e.g. form drop out data} 22
