Abstract
A system and method for contractively mapping decompressed images to facilitate resynchronization of data transmission is provided. This system includes a transmitter having a data compressor, a decompressor, and a contractive mapper. The receiver for the data transmission includes a decompressor and contractive mapper. The decompressor and contractive mapper of the transmitter provide the compressor with the same information which the decompressor at the receiver is using to decompress data. In this manner, the compressor may accurately represent the incoming frame data in terms of the contractively mapped decompressed data. The contractive mapper attenuates information in the decompressed data frame to prevent the persistence of erroneous data at the receiver should data become corrupted during transmission or the transmission be interrupted. The contractive mapping is preferably achieved with an affine map contracting scheme which is preferably implemented by a scalar multiplication.
