ABSTRACT:
An input picture signal is divided into blocks. The blocks are grouped into groups each having a plurality of blocks. The input picture signal is encoded into a second picture signal block by block. The second picture signal uses a variable length code. An error correction signal is added to the second picture signal for each of the groups. A signal of a start address and a signal of a location address are added to the second picture signal for each of the groups. The start address represents a position of a bit within each of the groups. The location address representing a spatial position of a block within each of the groups.
