摘要

报道了一种用于传输报纸的算术编码数据压缩编解码器。采用有限精度算法对中文文字和分辨率为24 Pels/mm的栅格照片报纸页进行压缩，获得了约10的压缩比。该编解码器于1992年5月在中国国家传输网投入使用。

Arithmetic coding data compression codec for newspaper facsimile

An arithmetic coding data compression codec for transmitting newspapers is reported. By using a limited accuracy algorithm to Chinese words and a rastered photograph newspaper page with resolution of 24 Pels/mm, a compression ratio about 10 has been obtained. This codec was put into use in May 1992 in the national transmission network of China.<>
