Decoding apparatus, decoding method, and computer-readable storage medium

Abstract

Provided are a decoding apparatus and method. The decoding apparatus includes a repository and a configuration unit. The repository stores a plurality of functional units having an input port and an output port which are respectively represented as tokens. The configuration unit receives decoder description which includes an identifier of at least one of the functional units and connection relationship information between the functional units, selects each functional unit corresponding to the received identifier from the repository, and connects the selected functional units by using the token to configure a variable decoder. The decoding apparatus and method defines the connection relationships between a plurality of functional units that configure a decoder, and thus can quickly and dynamically configure a decoder suitable for various encoding schemes. Accordingly, the decoding apparatus and method enable to easily verify suitability in each level of encoding, decoding and standardization and achieve the concentration of information, thereby accelerating the progress and standardization of technologies.
