In this paper, we propose a DWT-based video watermarking algorithm. It embeds multiple information bits into uncompressed sequences. Its features include: i) embedding data in the LL subband; ii) reducing error probabilities of detection by exploiting BCH code; iii) combating bursts errors using novel 3-D interleaving technique; iv) developing an effective temporal synchronization technique (compared with sliding correlation proposed Hartung and Girod, our is more advance); v) valid secure key needed extraction. Experimental results demonstrate that hidden algorithm visually transparent, robust against MPEG-2 compression, scaling 2.0, rate much lower than without when frame loss below 50%. The imperceptible high bit watermark thus embedded blind extracted. experiments have demonstrated effectiveness
