US Patent 7751486 Systems and methods for transmitting data

Presented herein are systems, methods, and devices for transmitting data comprising by comparing a new message with a buffered message representative of a previous message, recording an integer number of differences between the new message and the buffered message, generating a diff-word representative of the integer number of differences between the new message and the buffered message, appending the diff-word to the new message, and sending the new message with the diff-word to a receiver. The diff-word is used by the receiver to determine whether a received new message has the expected number of differences, and to determine whether to accept the new message.
