Abstract:
A high-speed image transfer system comprising:a bit map image source containing a selected image in bit map format; a first forward error-correcting generator connected to receive said image in bit map format and having an output line containing a first forward error-correcting code for the image in bit map format; a compressor which is also connected to said bit map image source to compress the image in bit map format to a compressed state to result in a compressed bit map signal; a combiner connected to receive both the first forward error-correcting code and the compressed bit map signal and form a first combined data stream; a former connected to said combiner to receive the first combined data stream and form the first combined data stream into data packets; a second forward error correcting generator for receiving the data packets and generating a second forward error-correcting signal and combining the second forward error-correcting signal with the data packets to form a second combined data stream; a transmitter to transmit the second combined data stream; a receiver connected to said transmitter to receive the second combined data stream; a first error detector and corrector connected to said receiver for utilizing the second forward error-correcting signal to correct any transmission errors in the compressed bit map signal to form a corrected compressed bit map signal; a decompressor connected to receive the corrected compressed bit map signal from said first error detector and corrector to decompress the received corrected compressed bit map signal; a bit map image generator connected to said decompressor for reconstructing a bit map image from the decompressed signal; a second error detector and corrector connected to said bit map image generator to utilize the first forward error-correcting code to detect errors and correct the reconstructed bit map image coming from said bit map generator to produce a corrected reconstructed bit map signal.
