摘要: Method of protecting a compressed video stream that can be decomposed into first shot composed objects type and second against errors during the transmission this over an unreliable link, characterized in it comprises at least following steps: a) analyzing domain (11, 12) so as to define various image zones which redundancy will added, motion estimation vectors transformed coefficients obtained are transmitted addition step, b) adding (13a, 13b, 14) said determined previous a), while taking account domain, c) transmitting all forming image.
