Abstract
A hardware implementation of the Eureka-standard data reduction codec is described. The algorithm employed is an adaptive intrafield/intraframe discrete cosine transform with adaptive quantisation and variable-length coding. Interframe editing, multiple copying and rapid search are guaranteed by the special codec architecture.
