ABSTRACT:
A moving-image signal encoding apparatus is provided in which information to be lost is suppressed to a minimum extent when a cell is lost in a transmission line. 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 the cells are lost in the transmission line, a decoding is allowed from the encoded words having particular meaning which appears at a first bit of bitstream succeeding to the lost cells.
