Embodiment Construction

[0044] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0045] General terms that are currently and commonly used are selected as the terms used in the present invention. And, there are terms arbitrarily selected by the applicant for special cases, and their detailed meanings are explained in detail in the description of the preferred embodiments of the present invention. Therefore, the present invention should be understood not from the literal meaning of the terms, but from the meaning of the terms.

[0046] In the present invention, the meaning of "decoding" includes encoding process and decoding process. However, it is obvious to those skilled in the art that a specific decoding process is only applicable to an encoding process or a decoding process, which will be distinguished in the following description of the corresponding components. And, "decoding" may also be calle...

Abstract

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 a number of data corresponding to a pilot reference value and if a number of data bands meets a predetermined condition, obtaining the pilot reference valueand a pilot difference value corresponding to the pilot reference value and obtaining the data using the pilot reference value and the pilot difference value. The number of the data is obtained usingthe number of the data bands in which the data are included.; The present invention includes the steps of deciding one of a plurality of data coding schemes using a number of data and decoding the data according to the decided data coding scheme, wherein a plurality of the data coding schemes include a pilot coding scheme at least.

Description

technical field [0001] The present invention relates to a signal processing device and its method, in particular to a data decoding device and its method. Background technique [0002] In general, many techniques for signal compression and restoration have been introduced so far. And, applicable targets of the corresponding technology are various data including audio data, video data, and the like. In addition, signal compression or restoration techniques are evolving toward improving audio or video quality at high compression ratios. In addition, much work has been done on improving the transmission efficiency adaptable to various communication environments. [0003] However, it is believed that there is still room for improvement in transmission efficiency. Therefore, a lot of work needs to be done to maximize the transmission efficiency of signals in very complex communication environments through the development of new signal processing schemes. Contents of the inve...
