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.

Abstract: Provided are encoding and decoding stitching information generated when the 3D mesh model that is the non-manifold or non-orientable model is converted into orientable and manifold models upon encoding the 3D mesh information of the 3D mesh model. The method of encoding 3D mesh information includes the steps of: encoding the 3D mesh information to output an encoded bitstream; encoding stitching information of elements contained in the 3D mesh information, the stitching information having a total number of duplicated original elements and, for each of the duplicated original elements, the duplication number, original-element identification information and duplicated-element identification information; and generating a packet of the bitstream, wherein the encoded stitching information is inserted into the packet.
