发明名称 WATER-MARK INDICATION OF SIGNAL WITH BITS VARIABLE FLOW
摘要 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. ^ 9 cl, 9 dwg, 1 tbl
