Abstract: The objective of the invention is to enable sharing, between layers in a network in which the layers are used to perform communications, resource information and information required for using paths. A network control system includes: a lower layer information storage unit, a lower layer control information conversion unit, an upper layer information storage unit, an upper layer control information conversion unit, an integrated layer information storage unit and a layer integration unit. The layer integration unit integrates, as virtual links, the information of flows, which are representative of communications among terminals in the lower layer, with the network information of the upper layer, thereby constituting the network information of the integrated layer. Further, the layer integration unit performs reciprocal exchanges of network information among the integrated layer information storage unit, the lower layer information storage unit and the upper layer information storage unit, said reciprocal exchanges including a process of giving, as the attribute information of the ports of the upper layer, label information required for using the virtual link provided by the lower layer.

Abstract: Present disclosure provides methods and apparatuses for monitoring motion in a video stream. The method comprises: identifying a motion of interest from motion present in a virtual stream, the virtual stream covering an area of the video stream at which motion is present, the motion of interest being a motion that is targeted for monitoring, wherein the area of the video stream being covered is controllable by a pan tilt value of the virtual stream; and adjusting the pan tilt value of the virtual stream to position the motion of interest at a centre of the virtual stream.
