We present a video watermarking technique proposed as an indexing technique for video sequences. The watermarking approach is based on an algorithm working in the spatial video domain, in order to reduce the computational cost, while the invisibility is obtained by masks computed in space and time domains. Finally, to improve robustness we work with different error correcting codes and we test their performances. The proposed scheme has been implemented and tested. Our tests are mainly focused on compression and transcoding attacks that are the most important operations that the video suffers in a journalistic report production. The robustness is increased by using an error correction code. The obtained results show that this is a good approach.
