Abstract:
The present invention relates to use of a circular buffer used by a peer in a multimedia streaming service based on peer-to-peer (P2P), and an operating method thereof. A circular buffer of the present invention may include a buffering section to process a delayed data fragment transmission request from at least one peer present in a network according to a playback of a multimedia content, a storing section to store data to be provided to the at least one peer, a continuous storing section in which data fragments for the playback of the multimedia content are stored in serial order, and a discontinuous storing section in which a space for a received data fragment to be shared with the at least one peer is reserved and a space for a data fragment to be received is reserved.
Abstract:
Disclosed is a method for receiving a multimedia content between peers on a peer-to-peer network, including: establishing a neighbor connection relationship which is a relationship to interactively transmit and receive the multimedia content, with the other peer on the peer-to-peer network; establishing a donator connection relationship to receive the multimedia content from the other peer, based on a donator approval request message transmitted to the other peer; receiving a multimedia content piece related message from the other peer based on the established donator connection relationship; and receiving a required multimedia content piece from the other peer according to a result of parsing the multimedia content piece related message.
Abstract:
An apparatus and method are provided for monitoring an antenna state of a mobile station. A resister may be provided between a battery voltage terminal and a power source voltage terminal of a power amplifier. A voltage level corresponding to a dropped amount of a voltage due to the resister may be generated and compared with a previously stored voltage level to determine whether current consumption of the power amplifier has been increased. If the increased amount of the current consumption of the power amplifier is large, the currently connected antenna may be determined to be in an abnormal state and a transmission path may be switched to another antenna. If two antennas provided in the mobile communication are in an electrically abnormal state, a baseband chip may inform a user of the abnormal state of the antenna. Accordingly, an output level degradation generated when the antenna is operated in an electrically abnormal state and shortening of the life span of a battery can be prevented. Thus, performance of an output terminal can be enhanced.

Abstract:
A method for automatically evaluating image data taking over a sequence of image frames to determine a contour of a left ventricle (LV). The sequence of image frames are converted to digital data that identify a gray scale value for each pixel in each image frame. Using probability, an initial LV region is estimated based upon previously determined a priori parameters that are derived from processing manually drawn contours of the LV in other hearts, for the sequence of image frames being analyzed. The initial estimate of the LV region is refined using motion constraints, which are also derived from training data determined from the manually-drawn contours of other hearts. An LV region is estimated and its coordinates are extracted for use in applying global shape constraints that provide a more accurate LV boundary estimate for the region around an apex of the left ventricle. Finally, the estimated LV boundary estimate is tested for consistency, yielding an accepted estimate, or warning that the estimate is unreliable. The resulting automatically determined contours of each image frame can be displayed almost immediately after the image data are produced so that a physician can more readily diagnose physiological defects of the heart.
Abstract:
A method of providing timing information for synchronizing packet streams delivered from a first server and a second server, respectively, that are different from each other under hybrid delivery service environment is provided. The first server delivers a first media object and the second server delivers a second media object. The timing information for synchronizing a second packet including the second media object and a first packet including the first media object is generated in the second server. The timing information and the second packet including the second media object are provided from the second server to the client.
Abstract:
Provided is a biodegradable thermoplastic resin composition including a cellulose derivative and surface-treated natural fiber. More particularly, in preparation of the biodegradable thermoplastic resin composition including the cellulose derivative and the natural fiber, a surface of the natural fiber is treated with alkali and/or sized, thereby increasing a density of the natural fiber, and an interfacial adhesion between the cellulose derivative and the natural fiber to improve a mechanical strength of the biodegradable thermoplastic resin composition. Furthermore, as the cheap natural fiber is used as a reinforcer, the production cost can be reduced.
