Abstract: An apparatus for compressing low-complexity 3D mesh, includes: a data analyzing unit for decomposing data of an input 3D mesh model into vertices information, property information representing property of the 3D mesh model, and connectivity information between vertices constituting the 3D mesh model; a mesh model quantizing unit for producing quantized vertices, property and connectivity information of the 3D mesh model by using the vertices, property and connectivity information; and a sharable vertex analysis unit for analyzing sharing information between shared vertices of the 3D mesh model. Further, the apparatus includes a data modulation unit for performing a circular DPCM prediction by using quantized values of the consecutive connectivity information of the 3D mesh model; and an entropy encoding unit for outputting coded data of the quantized vertices and property information, and differential pulse-code modulated connectivity information as a bitstream.

Abstract: PURPOSE: A distributed filtering apparatus and a method for the copyright protection of digital content are provided to be able to filter content depending on priority in a copyright search of the digital content. CONSTITUTION: A priority work node unit(304) selectively filters content with a copyright using plural priority work node databases. In case the content copyright existence is not determined in the priority work node unit, by using a plurality of the databases for the general work node, a general work node unit(306) selectively filters the content with copyright using plural general work node databases. A search server(302) controls a selective filter using the priority work node unit and the general work node unit according to the priority search regulation.
