ABSTRACT:
A picture decoding device of the present invention comprises a CPU, receiving as input encoded moving picture information, for subtracting ‘1’ from a slice start code inside slice information extracted from this information, a variable length code decoding circuit provided with a horizontal position generating circuit for subtracting ‘1’ from a macro block address (MBA) when output information formed from macro block position information (VP, HP), motion vectors, picture information etc. is output, using information output from the CPU, and a motion compensation circuit for carrying out decoding processing for the moving picture information, with origin coordinates set to (0,0), using a slice start code and macro block address after subtraction.
