Kertas kerja ini menerangkan pendekatan baharu kepada penanda air digital bagi gambar bergerak secara khusus untuk pengekodan video MPEG-4, yang berhasrat untuk meningkatkan keupayaan pengesanan ralat. Kaedah konvensional bukan sahaja tidak mempunyai keupayaan pengesanan tetapi juga keserasian dengan penyahkod video yang digunakan secara meluas hari ini. Oleh itu dalam pendekatan ini, tera air digital akan dibenamkan ke dalam pekali DCT (Discrete Cosine Transform) terkuantisasi untuk pengesanan ralat, di mana pencegahan kemerosotan kualiti gambar juga dicuba. Keputusan eksperimen ditunjukkan untuk menunjukkan bahawa keupayaan pengesanan ralat pendekatan yang dicadangkan bertambah baik dengan ketara, berbanding kaedah konvensional, dan kemerosotan kualiti gambar oleh penanda air adalah sangat kecil.

Abstract: This paper describes a new approach to the digital watermarking of motion pictures dedicatedly for the MPEG-4 video coding, which intends to enhance the error detection ability. The conventional method lacks not only the detection ability but also the compatibility with video decoders widely used today. Thus in this approach the digital watermarks are to be embedded into the quantized DCT (Discrete Cosine Transform) coefficients for the error detection, where the prevention of the picture quality degradation is also attempted. Experimental results are shown to demonstrate that the error detection ability of the proposed approach is significantly improved, as compared with that of the conventional method, and that the degradation of the picture quality by the watermarking is extremely small.
