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 group reference value corresponding to a plurality of data included in one group through data grouping and internal grouping for the data grouping and a difference value corresponding to the group reference value and obtaining the data using the group reference value and the difference value.
Claims20
A method of processing a signal, comprising the steps of:
- obtaining from the signal a group reference value corresponding to data included in a group through data grouping and internal grouping for the data grouping and a difference value corresponding to the group reference value;
- and
- obtaining the data using the group reference value and the difference value.
An apparatus for processing a signal, comprising:
- a value obtaining part configurable for obtaining from the signal a group reference value corresponding to data included in a group through data grouping and internal grouping for the data grouping and a difference value corresponding to the group reference value;
- and
- a data obtaining part configurable for obtaining the data using the group reference value and the difference value.
A method of processing a signal, comprising the steps of:
- generating a difference value using a group reference value corresponding to data included in a group through data grouping and internal grouping for the data grouping and the data;
- and
- transferring the generated difference value.
An apparatus for processing a signal, comprising:
- a value generating part configurable generating a difference value using a group reference value corresponding to data included in a group through data grouping and internal grouping for the data grouping and the data, wherein the group reference value is obtained from the signal;
- and
- an outputting part configurable for transferring the generated difference value.
