PURPOSE:To quickly encode and decode signals according to a variety of encoding systems by providing more than two processors with the same constitutions and more than two work RAMS with the same constitutions for each processor. CONSTITUTION:More than two processors 1 with the same constitutions and more than two work RAMs 2 with the same constitutions(FIFOs are used if necessary) for each processor are provided. The processor 1 is connected by one or more work RAMs 2, processes input and output, detects a changing point, refers to an encoding table and a decoding table and restores a picture. The processor operates cocurrently and independent of the other. Thus time required for encoding and decoding can be reduced roughtly to the inverse of the number of processors thereby attaining the quick processing.
