摘要： An encoder for encoding input data to generate corresponding encoded data is provided. The encoder identifies substantial reoccurrences of data blocks and/or data packets within at least a portion of the input data. The encoder then identifies, in respect of individual elements, where elements are unchanged and/or changed within the substantially reoccurring data blocks and/or data packets. Subsequently, the encoder encodes unchanged elements in the encoded data by employing at least one corresponding symbol, or at least one corresponding bit, for example a single bit, indicating an absence of change in the unchanged elements relative to corresponding elements in a reference data block and/or data packet. Moreover, the encoder encodes changed elements in the encoded data.
