Um novo método de ocultação de erros para vídeos MPEG, no qual vetores de movimento são ocultados em um fluxo de bits MPEG como marca d'água, é proposto neste artigo. Vários métodos convencionais ocultam regiões de erro usando vetores de movimento, que são reestimados em um processo de decodificação. Estes métodos, no entanto, apresentam dois problemas: (1) A precisão de um vetor de movimento reestimado é inferior à de um vetor de movimento estimado em um processo de codificação. (2) É necessária uma grande quantidade de cálculos para reestimar os vetores de movimento. O método proposto supera esses problemas usando vetores de movimento precisos ocultos. Ou seja, esconde vários bits em cada 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
