Bildkodierungsgerät mit mehreren Kodierern

摘要

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 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 encoders (1a to 1n). The widths of quantization of the respective encoders are determined so as to prevent deterioration in quality of a picture in its entire aspect. <IMAGE>
