Abstract
It is intended to determine widths of quantization of respective encoders to prevent deterioration in quality of picture in its entire aspect. A multi-coding apparatus comprises a plurality of encoders 1a to 1n for coding input data at variable rates, a bit allocator 4 supplied with estimated amounts of codes output from the respective encoders 1a to 1n, and a maximum transmission rate controller 3 for supplying a whole allocated amount of bits to the bit allocator 4 on the basis of the amounts of codes output from the respective encoders 1a to 1n.
