Abstract: A content management method includes transmitting content from a content provider device to a client device over a predetermined network; and adding additional information comprising original content location information of the content transmitted to the client device and elapsed playing time information of the content. A content management device includes a communication module which transmits content to, receives content from, or transmits content to and receives content from a device connected over a predetermined network; an additional information edit processing unit which generates additional information comprising original content location information of the content transmitted by the communication module and elapsed playing time information of the content, and inserts the additional information into the transmitted content; and a storage unit which stores the content into which the additional information has been inserted.

Abstract: A method and apparatus for updating the software of a device that is a controlled device linked to a control device over a network. According to the method, a control device obtains information regarding updating of the software of a controlled device, determines whether updating is available using the information, and allows the controlled device to update its software, thereby easily updating the software of device. The apparatus can be a network device, connected to an update server and another network device in a network, for updating software of the other network device. The network device can include a control circuit configured to determine whether the updating of the software is required based on update information; and a transceiving unit configured to communicate with the other network device and the update server.

Abstract: A portable apparatus and an operation method thereof are provided. The method includes accessing information on resources of a second portable apparatus, if the second portable apparatus is connected to a first portable apparatus; and operating the first portable apparatus using the accessed information on resources and information on resources of the first portable apparatus. The portable apparatus includes a connector which connects a first portable apparatus and a second portable apparatus; a storage unit which stores information on content and information on resources; a control unit which accesses information on resources, and controls the operation of the first portable apparatus using the accessed information on resources; and an output unit which outputs a signal, under the control of the control unit, wherein the storage unit outputs content data requested by the control unit.

Abstract: A method and system for providing a streaming service in a home network. The method includes requesting a streaming service and transmitting information about the priority of the request to the server, and connecting to the server, which selectively disconnects the connection of a client that has a priority lower than that of the transmitted request, depending on whether the requested streaming service is available, and receiving the requested streaming service.
