A moving-image signal encoding apparatus is provided in which information which might be lost is kept to a minimum when a cell is lost in transmission. A cell assembler divides a bitstream into cells of bits and adds to the cells positional information of encoded words having particular meaning within the cell. When cells are lost in transmission, a decoding is allowed from the encoded words having particular meaning which appear at a first bit of the bitstream following the lost cells.
L'invention est un appareil de codage de signaux d'images animées dans lequel les informations qui risquent d'être perdues sont réduites au minimum quand une cellule est perdue au cours d'une transmission. Un assembleur de cellules divise les chaînes binaires en cellules de bits et ajoute à ces dernières des informations de position sur les mots codés qui ont un sens particulier dans ces cellules. Quand des cellules sont perdues au cours d'une transmission, l'appareil de l'invention autorise un décodage des mots codés ayant un sens particulier qui apparaissent au premier bit de la chaîne binaire qui suit les cellules perdues.
