METHOD AND APPARATUS FOR SIGNAL PROCESSING AND ENCODING AND DECODING METHOD, AND APPARATUS THEREFOR

摘要

A method and an apparatus for signal processing, and encoding and decoding methods, and an apparatus thereof are provided to enable efficient data coding and entropy coding, thereby enabling data compression and recovery with high transmission efficiency. An encoding apparatus(1) includes at least one of a data grouping unit(10), a first data encoding unit(20), a second data encoding unit(31), a third data encoding unit(32), an entropy encoding unit(40), and a bitstream multiplexing unit(50). The second and third data encoding parts are integrated into one data encoding unit(30). The data grouping unit binds input signals by a predetermined unit to enhance data processing efficiency. Each of the data encoding parts encodes input data according to a corresponding encoding scheme. Each of the data encoding parts adopts at least one of a PCM(Pulse Code Modulation) scheme and a differential coding scheme. The bitstream multiplexing part arranges or coverts coded data to correspond to a transfer specification, and then transfers the arranged/converted data in a bitstream form.
