    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.

    摘要翻译： 控制MPEG-4系统的终端以便通过高速缓存机制更快地再现所选择的内容的方法包括：如果选择要被再现的内容，则MPEG-4系统的终端接收第一对象描述符 从服务器选择内容，然后基于初始对象描述符，对象描述符和场景描述确定流的对象和优先级。 在再现构成内容的随机对象的点处，随机对象被存储在高速缓存中。 如果存储在高速缓存中的对象的最终更新时间与存在于服务器中的对象的最终更新时间相同，则再现要求从缓存再现的对象。 因此，该方法使得可以更快速地再现用户请求的内容并向用户提供更稳定的内容。

    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.
