  • Dictionary-based compression and decompression
    Patent number: 7280057
    Abstract: The invention discloses a compressor for encoding data and a decompressor for decoding data. The data compressor comprises an encoder configured to encode a data file using a dictionary-based compression. The encoder is configured to reset the dictionary at least once while encoding the data file, thereby forming a plurality of encoded data blocks. The invention discloses also a data decompressor comprising a decoder configured to decode a data file compressed using a dictionary-based compression. The decoder is configured to recognize at least one block boundary within the data file and to restart decoding at the block boundary.
