WATER-MARK INDICATION OF SIGNAL WITH BITS VARIABLE FLOW Russian patent published in 2008 - IPC H04N7/26 H04N7/08 G06T1/00 

FIELD: information technologies.

SUBSTANCE: invention relates to the devices and methods for implementation and detection of water-marks in information signals. One proposed method and device of water-mark implementation in information signal (MPin), when administration of water-mark implementation process is fulfilled with, at least, one parameter of implementation. Implementation parameter value depends on transfer bit speed on information signal (MPin), and, at least, water-mark signals stability and its observability.

EFFECT: scheme creation of water-mark implementation, fitting water-mark implementation in different information signals, which can be broadcast with different speed of bit transfer.
