Compressive data hiding for video signals
Alexia Giannoula, Dimitrios Hatzinakos · 2004
Considerable research has been conducted lately on attempting to integrate the dual processes of signal compression and perceptual coding, in order to achieve high signal quality at low bit rates, while ensuring, at the same time, copyright protection of the transmitted digital media. An unconventional data hiding technique leading to compressed forms of source video signals, is introduced in this paper, where both the audio information and the chrominance (I and Q) components of the video frames are hidden in the wavelet transform coefficients of the luminance (Y) component, on a frame-by-frame basis. Furthermore, the proposed scheme allows for a subsequent JPEG compression of each frame for additional bitrate reduction, while maintaining satisfying quality of the reconstructed audio and chrominance information.
