Abstract: Multiple cameras are operatively connected over a shared link to a video server on a video network. The cameras are operated to capture a plurality of video streams. Each video stream has intra-frames and predictive frames that are sequentially generated timewise apart. A number of the video streams that transmit over the shared link on the network is identified. A number of intra-frames that are generated substantially simultaneously in the identified video streams is also identified. The identified intra-frames in the video streams are offset in time to minimize video artifacts from being present in the video streams being transmitted over the shared link.
Abstract translation: 多个相机通过共享链路可操作地连接到视频网络上的视频服务器。 操作摄像机以捕获多个视频流。 每个视频流具有按时间间隔顺序生成的帧内和预测帧。 识别通过网络上的共享链路传输的多个视频流。 还识别出在识别的视频流中基本上同时生成的多个帧内帧。 视频流中所识别的帧内在时间上偏移，以使通过共享链路传输的视频流中存在的视频伪像最小化。
