Abstract
A method and apparatus for signal processing which enable data compression and recovery with high transmission efficiency are disclosed. Data coding and entropy coding are performed with correlation and grouping is used to increase coding efficiency. A method for signal processing according to this invention, the method includes decapsulating the signal received over an Internet protocol network, obtaining data coding identification information from the de-capsulated signal and data-decoding data according to a data coding scheme indicated by the data coding identification information, wherein the data coding scheme includes at least a pilot coding scheme, the pilot coding scheme decodes the data using a pilot reference value corresponding to a plurality of data and a pilot difference value, and the pilot difference value is generated using the data and the pilot reference value.
