A method of encoding input data in an encoder to generate corresponding encoded data includes splitting and/or transforming the input data into data chunks, analyzing symbols present in the input data and compressing the symbols as a function of occurrence of the symbols in the data chunks; generating code tables, frequency tables, and/or length of code word tables for the symbols present in the data chunks; computing sets of indices relating the symbols in each data chunk and/or the compressed symbols to entries in the code tables, the frequency tables, and/or the length of code word tables; and assembling the sets of indices, together with the frequency tables, the code tables, and/or information indicative of such tables, for generating the encoded data. An encoder that utilizes the method, together with a corresponding decoder, wherein the encoder and the decoder in combination form a codec.
