Robust Digital Video Watermarking in the Spatial and Wavelet Domain

This paper presents two blind video watermarking techniques in the spatial and wavelet domain proposed by the authors and compares the two approaches. The original watermark and the original, unwatermarked videos are not required for the watermark extraction process. The two methods are combinations of spread-spectrum and quantization based techniques. The watermarks used are binary images, containing the copyright information. The watermark is protected against singular bit errors with a Hamming error correction code. The spatial domain technique embeds a watermark bit by spreading it in a luminance block. The actual embedding is done using a quantization based approach.
