Method of controlling terminal of MPEG-4 system using caching mechanism
First Claim
1. A method of controlling a terminal of an MPEG-4 system, the method comprising:
- identifying an object to be cached;
caching the object from a server and storing the same in a cache;
receiving a request to reproduce a requested object and determining whether the object stored in the cache includes the requested object; and
reproducing the requested object from the object stored in the cache, if the requested object is stored in the cache.

Abstract
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.

16. A terminal for use in reproducing MPEG-4 encoded data in objects received from a source, comprising:
-
an interface through which the terminal receives the MPEG-4 data from the source;
a memory;
an input unit which receives a request to play a requested object; and
a controller which, in response to the request to play the requested object, controls object data to be received from the source and stored in the memory, compares the stored object data with the requested object, and, if the stored object data corresponds with the requested object, reproduces the requested object using the stored object data retrieved from the memory. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A computer readable medium encoded with processing instructions for implementing a method of controlling a terminal of an MPEG-4 system performed by a computer, the method:
-
caching object data from a source and storing the cached object data in a cache;
receiving a request to reproduce a requested object and determining whether the stored object data includes the requested object; and
reproducing the requested object from the stored object data, if the stored object data includes the requested object. - View Dependent Claims (36, 42, 43, 44, 45, 46, 47, 48, 49, 50)
