Method and apparatus for signal processing

The present invention relates to a signal processing method and apparatus. Particularly, to a coding method for signal compression and recovery with the apparatus therefor in order to efficiently process the data transmitted over the network. Data coding and entropy coding are performed with interconnection, and grouping is used to enhance coding efficiency. A signal processing method of the present invention includes the steps of receiving a signal over the Internet network protocol decapsulation (decapsulation); Obtaining data coding identification information from the signal illustration the de-encapsulating; And according to the data coding scheme indicated by the data coding identification information, and a step of the data decoding the data. In addition, the data coding schemes include a pilot coding scheme at least to the pilot coding scheme is the pilot difference value decoding the data, and using the pilot reference value and the pilot difference value corresponding to a plurality of data and the data It is generated using the pilot reference value.
