    • A network video server (20) receives multiple sets of streaming data respectively transmitted from multiple network cameras (10) connected with the network video server (20). Each set of streaming data has a piece of first streaming data having a first image resolution and a piece of second streaming data having a second image resolution being lower than the first image resolution. The network video server (20) decodes the piece of first streaming data from one of the network cameras (10) into a frame of video data and outputs the frame of video data during a full-screen mode, and combines the decoded pieces of second streaming data from all network cameras (10) into a frame of video data and outputs the frame of video data during a split-screen mode. Accordingly, the sharpness and smoothness of video frames is secured during the full-screen and split-screen modes.
    • 网络视频服务器(20)接收分别从与网络视频服务器(20)连接的多个网络摄像机(10)发送的多组流数据。 每组流数据具有一段具有第一图像分辨率的第一流数据和具有低于第一图像分辨率的第二图像分辨率的第二流数据。 网络视频服务器(20)将来自网络摄像机(10)之一的第一流数据解码为视频数据帧,并在全屏模式下输出视频数据帧,并将经解码的第二片 将来自所有网络摄像机(10)的数据流传输到视频数据帧中,并在分屏模式期间输出视频数据帧。 因此,在全屏和分屏模式期间确保视频帧的清晰度和平滑度。
