    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.

    摘要: A method and system for communication between wireless networks connected through a wired network in a coordinator-based wireless network environment are provided. According to the method for communication, a wired/wireless relay device that attempts to associate with an initial coordinator-based wireless network notifies a coordinator of information indicating that it acts as a relay device. The coordinator sends the information to wireless network devices within an appropriate coordinator-based wireless network, and each of the wireless network devices transmits data to be transmitted to a device within a different coordinator-based wireless network to the relay device. When the relay device sends the data to a relay device in a coordinator-based wireless network a destination wireless network device belongs to through a wired network, the relay device in the same coordinator-based wireless network as the destination wireless network device sends the data to the destination wireless network device.
