Abstract (en)

[origin: WO2007043840A1] A method and apparatus for processing a signal compressed in accordance with a specific alternative coding scheme are disclosed. In detail, a coding method for signal compression and signal restoration using a specific alternative coding scheme, and an apparatus therefor are disclosed. Data coding and entropy coding according to the present invention are executed under the condition in which they have a co-relation with each other. The method for signal processing includes obtaining a pilot reference value corresponding to a plurality of data and a pilot difference value corresponding to the pilot reference value, and obtaining the data using the pilot reference value and the pilot difference value.
