Disclosed herein is a system and method for providing a supplementary information associated with a broadcast content. The system provides a supplementary information associated with a specific broadcast program in the broadcast content by means of a supplementary information server, wherein the supplementary information server comprises a broadcasting receiving unit for receiving the broadcast content; a synchronization information unit for storing a synchronization information of the supplementary information associated with the specific broadcast program; a video comparison unit for comparing screens of the broadcast content with a previously stored scene change screen of the specific broadcast program and setting a start time of the specific broadcast program; a supplementary information extracting unit for calculating an elapsed time from the start time of the specific broadcast program to a specific screen and extracting the supplementary information corresponding to the elapsed time. The supplementary information associated with the specific broadcast program in the broadcast content is provided through the steps of receiving a synchronization information of the supplementary information associated with the specific broadcast program; setting a start time of the specific broadcast program by comparing screens of the broadcast content with a previously stored scene change screen of the specific broadcast program; calculating an elapsed time corresponding to a specific screen based on the start time; extracting the supplementary information corresponding to the elapsed time.

System and method for synchroning broadcast content with supplementary information

Provided is a power allocation method and apparatus for providing a packet data service in a mobile communication system is capable of reducing outage of a line service while simultaneously providing the line service and the packet service. It is checked whether or not packet data traffic to be transmitted to a specified mobile station is newly generated. If the packet data traffic is newly generated, it is checked whether or not there is the mobile station making use of the line service where a current call is in progress. If there is the mobile station making use of the line service where the current call is in progress, it is checked whether or not the packet data traffic is currently transmitted to any other mobile station. If the packet data traffic is not currently transmitted to the other mobile station, the power transmitted to the mobile station making use of a new packet data service is gradually increased by a preset increment for a preset predetermined time. Thereby, it is possible to innovatively reduce the outage of the mobile station making use of the line service while simultaneously providing the line service and the packet service as compared with the prior art.
