Abstract

An encoding method and apparatus and a decoding method and apparatus are provided. The encoding method includes encoding data, generating a data bit array comprising the encoded data and encoding information, and generating an align bit array comprising one or more 1s. According to the encoding method and apparatus and the decoding method and apparatus, it is possible to enhance the quality of decoded data by inserting various information into an align bit array that is included in a bitstream for aligning a plurality of encoded data bit arrays with one another. In addition, according to the encoding method and apparatus and the decoding method and apparatus, it is possible to efficiently utilize data bandwidths that are allocated for the encoding/decoding of data at low bitrates by enhancing the efficiency of data encoding.
