| 20080207205 | Method of Hand-Over In the Mixed Network of Asynchronous Communication Network and Synchronous Communication Network - In the present invention, as a mobile communication terminal, which is using service in the area of an asynchronous mobile communication system, detects signals from a synchronous mobile communication system, the mobile communication terminal repeatedly performs a process of examining whether, in a predetermined time, signals from the asynchronous mobile communication system have been detected a designated number of times, and measuring the intensity of the signals. When the number of times that the intensity of signals from the asynchronous mobile communication system is smaller than a designated number of times, or no signals from the asynchronous mobile communication system are detected, within the predetermined time, it is determined whether to perform handover of the mobile communication terminal. | 08-28-2008 |
| 20080205419 | Residential Gateway System for Home Network Service - Disclosed herein is a Residential Gateway (RG) system for home network service. The RG system receives various supplementary services through a Home Network Serving Node (HNSN) that provides home network service. The system includes an Open Service Gateway initiative (OSGi) framework, an RG agent, a virtual Universal Plug and Play (UPnP) device, and a Java virtual machine. The RG agent is installed on the OSGi framework and implemented in bundle form. The UPnP device is registered on the OSGi framework by the RG agent. The Java virtual machine is ported by the RG agent to hardware on which an operating system is installed. | 08-28-2008 |
| 20080198922 | Systems and Methods For Video Quality Measurement Using Auxiliary Information of Codec - A system for evaluating video quality using auxiliary information of a codec includes a video transmitter that includes a source video input unit for inputting source video, an encoding unit for encoding the input source video, a decoding unit for decoding encoded video data, and a video quality evaluation unit for evaluating video quality using the decoded video data. The encoding unit transmits auxiliary information required for video quality evaluation, among information acquired in an encoding procedure, to the video quality evaluation unit. The video quality evaluation unit evaluates video quality using the decoded video data received from the decoding unit, and the auxiliary information received from the encoding unit. | 08-21-2008 |
