  • Publication number: 20210281571
    Abstract: A smart process control switch can implement a lockdown routine to lockdown its communication ports exclusively for use by devices having known physical addresses, enabling the smart process control switch to prevent new, potentially hostile, devices from communicating with other devices to which the smart process control switch is connected. Further, the smart process control switch can implement an address mapping routine to identify “known pairs” of physical and network addresses for each device communicating via a port of the smart process control switch. Thus, even if a new hostile device is able to spoof a known physical address in an attempt to bypass locked ports, the smart process control switch can detect the hostile device by checking the network address of the hostile device against the expected network address for the “known pair.

  • Publication number: 20210266613
    Abstract: A processor system and computer-implemented method may be provided for generating a composite video stream which may combine a background video and a foreground video stream into one stream. For that purpose, a spatially segmented encoding of the background video may be obtained, for example in the form of a tiled stream. The foreground video stream may be received, for example, from a(nother) client device. The foreground video stream may be a real-time stream, e.g., when being used in real-time communication. The image data of the foreground video stream may be inserted into the background video by decoding select segments of the background video, inserting the foreground image data into the decoded background image data of these segments, and by encoding the resulting composite image data to obtain composite segments which, together with the non-processed segments of the background video, form a spatially segmented encoding of a composite video.

  • Publication number: 20200404375
    Abstract: A system and method for rendering a video stream for display on a display device, which may comprise receiving the video stream by streaming and generating display data defining a visible display area to be displayed by the display device, wherein said generating of the display data comprises rendering the video stream in a sub-area of the visible display area. A selection mechanism may be provided by which a version of the video stream may be selected for streaming having a spatial resolution and/or a bitrate which is selected based on a size of the sub-area. Thereby, the video stream may be adapted in terms of visual quality to the effective spatial resolution provided by the sub-area. For a smaller sub-area, it may be avoided to stream a version of the video stream which contains spatial detail which cannot be perceived when the video stream is rendered in the sub-area but which may incur more technical cost, e.g.
