In this work, a robust watermarking algorithm is presented for video copyright protection. The algorithm is based on hybrid transforms using the combination of DWT and DCT. In the scheme, the luminance component of the key frames is firstly decomposed by a DWT, and then the approximation sub-band in the wavelet domain is selected on which DCT is applied. Following that, the watermark information which is sorted by the pseudo-random and encoded by Turbo codes is embedded into the DCT domain. The
