H04N1/32341 - CPC Classification

Classification description:

Scanning, transmission or reproduction of documents or the like, e.g. facsimile transmission; Details thereof; Circuits or arrangements for control or supervision between transmitter and receiver or between image input and image output device, e.g. between a still-image camera and its memory or between a still-image camera and a printer device; Display, printing, storage or transmission of additional information, e.g. ID code, date and time or title embedded in the image data, i.e. enclosed or integrated in the image, e.g. watermark, super-imposed logo or stamp; Methods relating to embedding, encoding, decoding, detection or retrieval operations Blind embedding, i.e. the original image not being known beforehand
