Abstract
An operational video compressor was built using field-to-field differencing, on fields processed using Landau and Slepian's Hadamard transform method. Because of disturbing motion artifacts, the system was partially redesigned to repeat fields or frames. The spatial resolution was improved using a fixed-rate, three-mode adaptive system to compress each field. A substantial performance improvement was achieved while the transmission rate, memory size, and much of the hardware remain unchanged.
