The first quality represents the occurrence in a field of view of the video camera of the defined event of interest detected by the video analytics. The second quality represents the nonoccurrence in the field of view of the defined event of interest detected by the video analytics. Storing video data of first and second qualities reduces system storage capacity demands.

A video surveillance system includes a plurality of video sources, where each video source is arranged to monitor and acquire video surveillance data within a field of view (FOV), a video manager connected to each of the plurality of video sources to control the video sources and to process video surveillance data acquired therefrom and a user interface connected to the video manager that allows an end-user to observe the FOVs from each of the plurality of video sources, and identify a region of interest (ROI) within particular FOVs to dynamically render a composite FOV comprising the ROIs from the particular FOVs. Where a video source includes enhanced abilities, such as a mega-pixel camera or video source, the enhanced video source may forward, instead of video data for the entire FOV, only that video dated from the selected ROI to realize reduced network traffic for more optimal video surveillance applications.

Systems and methods for network transmission of three-dimensional graphical data are disclosed. A single graphical application instance can virtually and efficiently exist on multiple local or remote display systems by directly sharing its raw rendered framebuffer memory information among all local or remote graphics accelerators, thus avoiding the need to re-render any application information again on each node. An internal graphics card is used to scale the rendered data prior to transmission. This graphics scaling eliminates the need for data compression or image compression and achieves an adaptive, hardware-accelerated reduction in network bandwidth. Furthermore, since all memory and remote processing support tasks are performed within the graphics card, the CPU, system bus, and memory bandwidth remain available to the system and other applications.
