<p>PURPOSE:To cut the propagation error of encoding data at a reception side by generating address information corresponding to the leading position of other data at every sync block, and attaching the address information on a corresponding sync block. CONSTITUTION:A block forming circuit 3 converts a digital image signal into data of block structure, and an encoder circuit 5 divides the encoding data into significant word data representing the characteristic of the block and the other data. A circuit 6 forms the sync block by re-arranging the encoding data so as to arrange the other data between the significant word data, and the circuit 6 generates the address information corresponding to the leading position of the other data at every sync block, and attaches the address information on a corresponding sync block. Thereby, it is possible to prevent a propagation error continued until one frame period is completed even when an error exists in a dynamic range DR.</p> |
