| 摘要 |
An apparatus for processing a signal and method thereof are disclosed. Data coding and entropy coding are performed with interconnection, and grouping is used to enhance coding efficiency. The present invention includes the steps of obtaining data coding identification information and decoding data according to a data coding scheme indicated by the data coding identification information. The data coding scheme includes a pilot coding scheme at least, wherein the pilot coding scheme decodes the data using a pilot reference value corresponding to a plurality of the data and a pilot difference value, and wherein the pilot difference value is generated using the data and the pilot reference value.
