    摘要: A method of controlling a terminal of the MPEG-4 system to enable to faster reproduce the selected contents through a caching mechanism includes, if the contents to be reproduced is selected, the terminal of the MPEG-4 system receives an initial object descriptor of the selected contents from a server, and then determines an object of stream and the priority based on the initial object descriptor, object descriptor, and a scene description. A random object is stored in the cache at the point of reproducing the random object constituting the contents. If a final update time of the object stored in the cache is identical with that of the object existing in the server, the object requested to be reproduced from the cache is reproduced. Accordingly, the method makes it possible to more promptly reproduce the contents requested by a user and to provide more stable contents to the user.
