Abstract
A method of encoding data (D1) for generating corresponding encoded data (E2) is provided, wherein the method includes: (a) analyzing the data (D1) to be encoded to identify one or more structural features within the data (D1); (b) encoding the data (D1) to be encoded as one or more portions depending upon the one or more structural features, and selecting one or more methods which efficiently encode the one or more portions, wherein the one or more methods include at least one extrapolation encoding method; and (c) generating the encoded data (E2) by combining data generated from the one or more portions, wherein the encoded data (E2) includes information indicative of methods employed to encode the one or more portions with their associated parameters. A method of decoding encoded data (E2) for generating corresponding decoded data (D3) is provided, the method includes: (a) processing the encoded data (E2) to extract therefrom data corresponding to one or more portions, wherein the extracted encoded data (E2) includes information indicative of methods employed to encode the one or more portions with their associated parameters; (b) decoding the one or more portions, wherein the d…
