摘要：There are several protocols and embedding techniques which are used to hide data digitally for an object in highly sophisticated environment. These protocols and technique must fulfil a number of requirements correctly applied for steganography. The purpose of this experimental study is to measure the quality of embed watermarks in video signals and to hide confidential data over it without any change and loss of data. The main focus of this paper is that we use two video clips which are bbc.avi and apple.avi. Here we set some parameter value for both clips as mention above. We are varying the quality of referenced image from 100-20% with unit difference 20% and extract the watermarks image with the value of control parameter NC
