A predictive coding system is disclosed wherein an input data sequence (at a) sequentially including a number of samples (at b to d) is subjected to time-base expansion (at e to g) by n times, where n is an integer not smaller than 2, using an interval of a predetermined period including a plurality of samples as a unit to form n-channel data sequences, and said n-channel data sequences are input in n predictive coding means (6 to 8) in parallel. The coded sequences may then be time-base compressed and then multiplexed (at h). A decoding system may operate in a somewhat similar manner. |
