Dengan kemunculan video digital dan penyiaran digital, perlindungan hak cipta data video telah menjadi salah satu isu yang paling penting. Kami membentangkan dalam kertas ini kaedah baru tera air digital untuk data video berdasarkan transformasi wavelet diskret. Dalam kaedah ini, kami membenamkan tera air dalam komponen frekuensi terendah bagi setiap bingkai dalam video tidak berkod dengan menggunakan proses pengkuantitian terkawal. Tera air boleh diekstrak terus daripada video yang dinyahkod tanpa akses kepada video asal. Keputusan eksperimen menunjukkan bahawa kaedah yang dicadangkan memberikan imej tera air dengan kualiti yang lebih baik dan teguh terhadap pengekodan MPEG dan pengekodan semula. Tambahan pula, kami membincangkan berbilang penanda air berkenaan dengan kawalan salinan generasi untuk kandungan video.

Hisashi INOUE, Akio MIYAZAKI, Takashi ARAKI, Takashi KATSURA, "A Digital Watermark Method Using the Wavelet Transform for Video Data" in IEICE TRANSACTIONS on Fundamentals,
vol. E83-A, no. 1, pp. 90-96, January 2000, doi: .
Abstract: With the advent of digital video and digital broadcasting, copyright protection of video data has been one of the most important issues. We present in this paper a novel method of digital watermark for video data based on the discrete wavelet transform. In this method, we embed the watermark in the lowest frequency components of each frame in the uncoded video by using a controlled quantization process. The watermark can be extracted directly from the decoded video without access to the original video. Experimental results show that the proposed method gives the watermarked image of better quality and is robust against MPEG coding and re-encoding. Furthermore, we discuss multiple watermarking with regard to the generational copy control for video contents.
