  • Patent number: 7958253
    Abstract: A method and apparatus are provided for transmitting and receiving a stream of content in a distributed storage system. According to the method, a stream of a copy of content is received from a plurality of storages being distributed in a network, wherein an original of the content is stored in a server and archival fragments of the copy of the content are separately stored in the storages, and a stream of the original content is selectively received according to the quality of the copy of the content, wherein the quality is determined based on the number of archival fragments received from the storages. Accordingly, it is possible to prevent degradation in the quality and reliability of content when archival fragments of a copy of the content are received from a distributed storage, thereby stably receiving a high-quality content streaming service.

  • Patent number: 7693934
    Abstract: A network device having a message receiving module for receiving notify messages transmitted from controlled devices connected in a network, a device list management module for collecting information regarding the controlled devices connected in the network and creating and managing a list of service information of all the controlled devices connected in the network, and a control module for searching for service information of a specific controlled device, which has been requested by a control point, in the device list management module and transmitting the searched information. Since a controlled device has a list of other controlled devices connected thereto in a network, when a message searching for a specific controlled device has been received from a control point, another controlled device can transmit a response message to the control point on behalf of the specific controlled device even though the specific controlled device cannot receive the message from the control point.
