Abstract
Abstract Machine encoding of forms allows a simple recognition system to determine what marks on the form bear relevant information and, then to transmit only the relevant information, i.e. transmits bit maps representing the unique parts of the form and a description of the form itself but not a bit map of the entire form. Depending on the architecture of the system and the needs of the user, the original document may be processed at the reception site after only a small fraction of the document' contents has been transmitted. Transmission of bit mapped information is thus proportional only to the size and density of the bit map to be transmitted. Transmission of other types of information, e.g. checkboxes or ASCII coded data, is proportional to the number of such items, and not their size or density.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
144 words
A method for transmitting a form from a transmitting device to a receiving device, which form has a generic part and a unique part, comprising the steps of: a) storing a description of the generic part in a memory location within the receiving device; b) encoding a pointer on the form, said pointer specifying the memory location within the receiving device in which the description of the generic part is stored; c) scanning the form to detect the pointer and the unique part; d) creating a digital encoding of the pointer and a bit map of the unique part; e) transmitting the bit map and the digital encoding to the receiving device; f) retrieving the description of the generic part from the storage location specified by the pointer; and g) regenerating the form in the receiving device from the bit map and the description.
Claim 2
Independent Claim
144 words
