An Update on Crosfield Data Compression Technology

A brief introduction will review the various approaches to data compression which have been implemented by Crosfield Electronics Limited for the effective compression of both halftone and full color continuous tone data. Specific high-speed hardware implementations of these data compression techniques are now installed in the field, and these will be reviewed with particular emphasis on data rate and compression ratios actually achieved in practice. The paper will conclude with a review of the application areas for data compression specifically in the fields of data communications and a system networking.
