The present invention relates to a system for tracking an object. The system includes an image capturing unit configured to capture a video of a predetermined observation area and output the captured video; and a multi-object tracker configured to output an object-tracking image by tracking multiple objects within an object image which is generated by extracting the objects from each of image frames obtained from the video obtained from the image capturing unit, wherein the multi-object tracker determines whether occlusion of the objects or hijacking occurs while performing multi-object tracking, and when it is determined that at least one of the occlusion and hijacking occurs, the multi-object tracker outputs the object-tracking image corrected by removing the occurring occlusion or hijacking.

A method and apparatus for predicting video traffic are provided. The method includes extracting the statistical properties of previous Moving Picture Experts Group (MPEG)-4 video traffic and predicting the size of a subsequent frame based on the statistical properties of the previous MPEG-4 video traffic. Therefore, it is possible to address such problems associated with traffic bursts as transmission delays or low throughputs and thus to improve the performance of communication and network systems that transmit video traffic.

Disclosed is a composite service control system resolving a conflict. A triggering condition of a new application that requests a registration is determined. When the determined triggering condition overlaps with a triggering condition of an existing registered application, determinations are made whether an intersection between an explicit conflict set of the new application and an explicit conflict set of the existing application exists and whether an intersection between an implicit conflict set of an API of the new application and an implicit conflict set of an API of the existing application exists; and The triggering condition and execution information of the existing application is reported. When either of the intersections exists, a defining of a conflict resolution policy or a changed application triggering condition for the new application is requested; otherwise the triggering condition and the execution information of the new application is stored in an information database.

Provided are a method and system for providing a multicast service in a next-generation network (NGN), which can improve the quality-of-service (QoS) of broadcast services by separating a routing path calculation function and a resource allocation function during the setting of a multicast broadcast channel and enabling a resource control server to perform centralized resource control. In the method and system for providing a multicast service in an NGN, a multicast router calculates a routing path, and a number of multicast routers on the calculated routing path issue a request for resources for a desired multimedia broadcast channel, and a resource control server allocates resources to the multicast routers on the calculated routing path.

A command input method makes use of a three-dimensional motion recognition device embodied with an inertia system and is particularly directed to extend the total number of inputable commands using initial posture information as well as movement pattern of a motion recognition device. The command input method includes the steps of: determining initial posture at start point when movement of the motion recognition device is generated; determining a pattern of the movement at the end of the movement; and deciding a command from the determined initial posture and the movement pattern. Since the three-dimensional spatial motion can be further differentiated into different commands by the initial posture of the input device, the command input system can be simplified in structure with less number of recognizable motions.

A congestion control access gateway and a congestion control method for the same are provided. The congestion control access gateway interfaces between a broadband convergence network and a ubiquitous sensor network including sensors and terminals. The congestion control access gateway receives data from the ubiquitous sensor network. When a congestion situation has occurred, the congestion control access gateway detects the congestion situation based on data received in the congestion situation and broadcasts congestion notification and control messages in response to the congestion situation detection. The congestion control access gateway generates a congestion situation detection profile as a result of the congestion situation detection and performs priority queuing of the received data based on the congestion situation detection profile and service classes. The congestion control access gateway determines destination of the queued data using the congestion situation detection profile and routes the data to a corresponding service.

Provided are an IPTV service system and a method thereof. The IPTV service system includes: a headend, a set-top box, and a plurality of multicast routers. The headend assigns a multicast group address for each channel and assigns a source address for each PID with respect to an MPEG-TS and packetizes the MPEG-TS into a plurality of packet streams. The set-top box identifies a user-selected channel and the necessary elementary streams in the MPEG-TS for the selected channel, and requests selective reception of only packet streams corresponding to the selected channel and the necessary elementary streams from the plurality of packet streams. The plurality of multicast routers form a multicast path between the headend and the set-top box. Accordingly, while services such as a multi-angle service, a multi-lingual service, a mosaic EPG service, and a personalized EPG service are realized in one multicast control method together with viewing of a general broadcasting channel, efficient use of bandwidth can be achieved.
