Abstract: PROBLEM TO BE SOLVED: To provide various editing/authoring functions for object-based interactive multimedia contents by considering each body existing in video, audio and still images as one object and to perform an interactive manipulation on an object basis which can easily re-edited/authored resulting to edit user interactivity, which is possible to respond to the various requests by users. SOLUTION: An apparatus includes a means for supplying an interface for editing object-based interactive multimedia contents by using a multimedia information editing and authoring tool, a processing means for converting the multimedia contents supplied from the user interfacing means on object basis to an object-based internal material structure supporting the editorial information authoring, storing it, converting the form of interactive multimedia content information stored as the internal material structure to a file form so as to perform an input or output process of the content and a means for encoding and decoding interactive multimedia content information supplied from the processing means.

Abstract: The present invention discloses a vertex position multistage-compression method of 3-D graphics models using predictive residual vector quantization. It is an object of the present invention to provide a compression method for compressing vertex position data of a 3-D graphics model into multilevel by repeatedly performing a process by which predictive errors of vertex position are vector-quantized and then compressed, and the predictive residual signals are calculated and vector-quantized. To accomplish the object, the compression method according to the present invention, which is applied to an encoding and decoding apparatus of 3-D graphics models, includes (1) obtaining predictive errors of vertex position and then vector-quantizing/compressing them; and (2) obtaining quantization errors, repeatedly performing vector-quantization process for the obtained quantization errors and then compressing them into multistage.
