<p><P>PROBLEM TO BE SOLVED: To reliably control composition of a scene and ensure the frequency of events generated by a time-dependent node included in the scene when coded multimedia data composed of several objects such as animations, still images, texts, CG and the like are distributed and received. <P>SOLUTION: A multimedia data distribution device 100 sets frame rate information for controlling composition of scene describing data by using a specified method of designating object describing data. A receiver 108 decodes the frame rate information from the object describing data in an object describing data decoding circuit 112 and inputs it to an event generation circuit 111. The event generation circuit 111 controls operations of a scene composing circuit 114 according to the frame rate information. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
