Method of processing a signal and apparatus for processing a signal

摘要

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. Grouping is executed for an enhancement in coding efficiency. The method for signal processing includes obtaining data coding identification information from a signal, and data-decoding data in accordance with a data coding scheme indicated by the data coding identification information. The data coding scheme includes at least a pilot coding scheme. The pilot coding scheme includes decoding the data using a pilot reference value corresponding to a plurality of data and a pilot difference value. The pilot difference value is generated using the data and the pilot reference value.
