    • PROBLEM TO BE SOLVED: To provide a server apparatus for displaying a video data stream in the case where a specific activity of interest is generated in a security environment. SOLUTION: In a server 800 capable of transmitting to a display device video data captured by a plurality of cameras 103-105, the video data obtained by the plurality of cameras 103-105 and times of events associated with the plurality of cameras 103-105 are recorded. A message requesting video data is received from a client 700 and in response to the message, a time difference between the times of the events and a playback time of video data being played back on the display device is determined. If the time difference is settled within a predetermined threshold as a result of the determination, the video data are transmitted to the client 700 so as to decelerate a reproduction speed of the video data in response to the dime difference rather than the case where the time difference is not within the predetermined threshold.

    • 要解决的问题:提供一种在安全环境中产生感兴趣的特定活动的情况下显示视频数据流的服务器装置。 解决方案:在能够向显示设备发送由多个摄像机103-105捕获的视频数据的服务器800中,由多个照相机103-105获得的视频数据和与多个照相机相关联的事件时间 103-105被记录。 从客户端700接收请求视频数据的消息,并且响应于该消息,确定在显示设备上正在播放的事件的时间和正在播放的视频数据的播放时间之间的时间差。 如果作为确定的结果将时间差定在预定阈值内,则视频数据被发送到客户端700,以便响应于一毛钱差而减小视频数据的再现速度,而不是时间 差异不在预定阈值内。 版权所有(C)2011,JPO&INPIT
