Faced with the continuous increasing of processing and storage capabilities in the digital world, the intellectual right holders consider watermarking as an appropriate mean to protect their property. Emerging from the mobile network environments, the youngest member of the watermarking application family is the low rate video protection. This paper reconsiders an outstanding informed coding method developed for grey level still images and adapts and extends it for such colour video. The experiments were carried out in cooperation with the SFR wireless service provider in France and pointed to the significant improvements in some practical applications. These results also allow a comparison between the spread spectrum and informed watermarking techniques in the mobile networks.
