Abstract:- Music, video, and 3D characters are just some content examples that imposed themselves as a very important component of data distribution to mobile terminals. Hence, to reliably ascertain and protect the related property rights is nowadays a crucial issue. This paper presents a study devoted to robust video watermarking in mobile networks: it reconsiders a method developed for regular networks and re-evaluates it under the mobile constraints. Experiments were carried out in cooperation with the SFR wireless service provider in France. The obtained results fulfil properties as: robustness (with respect to common attacks), transparency, obliviousness, and low probability of false alarm. Key-words: - robust video watermarking, mobile networks, spread spectrum, DCT, DWT.
