Abstract: The present invention relates to an apparatus and a method for receiving signal for extent of timing synchronization in MB-OFDM UWB System. The invention divides the digital samples completed of sampling twice as much as minimum sampling clock required to restore the MB-OFDM received signal into ODD data path and EVEN data path, executes the packet detection and timing synchronization for each of divided path and selects the data of path with larger cross correlation value at the timing synchronization point to secure the stable receiving performance in system environment with severe frequency offset and prevent the FTT window shift within preamble section through adding minimum hardware and structural change without increasing the system clock.

Abstract: Provided are a home network client and server including an energy-away control element (ECE), and a control method thereof. A client advertises an ECE serving as a functional block of each service unit. The advertisement is recognized and the ECE is registered by a plug and play method. An ECE to be controlled is searched and selected among registered ECEs. State checking and management are performed on the selected ECE. The ECE is defined by each service unit in the home network server and client, and energy is controlled for each ECE, so that the energy consumption can be reduced.

Abstract: Provided is a method and system for streaming multimedia data between hetero UPnP networks configured of a private network. The method comprises establishing a communication channel with a relay peer; establishing a virtual communication channel with a specific extensible home connector selected from a plurality of extensible home connectors connected with the relay peer; searching multimedia data to play from multimedia data in the specific extensible home connector which exists on the UPnP network through the virtual communication channel; establishing a communication environment through the UPnP internet gateway of the specific extensible home connector in case of demanding play of the searched multimedia data; and receiving multimedia data from the specific extensible home connector through the communication environment.

Abstract: Provided is an apparatus and method for creating device association/control information for realistic media representation. The device includes a media analyzer, a device information creator, a device parameter creator, a device attribute database, a device control information creator, and a device control stream creator. The media analyzer analyzes media to determine control values and control times for control parameters of respective devices to be associated for media reproduction. The device information creator creates device information by searching peripheral devices connected to a media reproduction device. The device parameter creator creates device parameter information by extracting controllable factors for the respective devices. The device attribute database stores the device information and the device parameter information. The device control information creator creates device control information including control values and control times for the respective device parameters.

Abstract: Provided are a receiver with a CA function based on software download, a CA system including the receiver, and a method for managing CA software executed by the receiver. The receiver includes a CA software management means, a download means, a demultiplexer, and a descrambler. The CA software management means performs an overall management operation including the download, execution, state control and termination of a plurality of CA softwares. The download means downloads the CA software from a CA software download server at the request of the CA software management means. The demultiplexer receives scrambled multimedia contents and a CA message and transfers the CA message to the CA software management means. The descrambler receives a descrambling key extracted from the CA message by means of the CA software and descrambles the scrambled multimedia contents with the descrambling key. Thus, a plurality of CA softwares can be operated in one receiver (e.g., a settop box).
