Une nouvelle méthode de dissimulation d'erreurs pour les vidéos MPEG, dans laquelle les vecteurs de mouvement sont cachés dans un flux binaire MPEG sous forme de filigrane, est proposée dans cet article. Plusieurs méthodes conventionnelles masquent les régions d'erreur en utilisant des vecteurs de mouvement, qui sont réestimés lors d'un processus de décodage. Ces méthodes présentent cependant deux problèmes : (1) La précision d'un vecteur de mouvement réestimé est inférieure à celle d'un vecteur de mouvement estimé dans un processus de codage. (2) Une grande quantité de calculs est nécessaire pour réestimer les vecteurs de mouvement. La méthode proposée surmonte ces problèmes en utilisant des vecteurs de mouvement cachés et précis. Autrement dit, il cache plusieurs bits dans chaque 8

Abstract: A new method of error concealment for MPEG videos, in which motion vectors are hidden in an MPEG bitstream as a watermark, is proposed in this paper. Several conventional methods conceal error regions by using motion vectors, which are re-estimated in a decoding process. These methods, however, have two problems: (1) The accuracy of a re-estimated motion vector is lower than that of an estimated motion vector in an encoding process. (2) A large amount of calculation is required to re-estimate motion vectors. The proposed method overcomes these problems by using hidden accurate motion vectors. That is, it hides several bits in each 8
