Abstract
A method of encoding source data to generate corresponding encoded data for transmission or storage includes matching one or more portions of the source data to one or more elements in one or more databases, wherein the one or more elements are representative of corresponding one or more data blocks, and recording reference values which relate the one or more portions of the source data to the one or more matched elements; and including the reference values in the encoded data together with the one or more databases and/or information identifying the one or more databases. The methods are implemented in an encoder, a decoder and in a codec. In the codec, the at least one encoder and the at least one decoder share one or more databases referred to by reference values included in the encoded data.
