  • Patent number: 11825156
    Abstract: To perform evidentiary analysis on media files generated by a video surveillance system, a media file is analyzed to determine the format of the media file. Information about that format is used to decode media files from that video surveillance system into separate streams of media data. A computer system assists a person in defining logical parameters that can be used to parse and decode a media file of a particular type and outputs corresponding format data. The format data includes data that instructs a decoder how to decode media files of that type. A second computer system that provides analysis tools includes the decoder, which receives one or more media files of a particular type and corresponding format data for that type. The second computer system can access and process each of the separate streams individually for playback or other image or media processing.

  • Patent number: 11678426
    Abstract: A commissioning system and method that applies a design configuration, representative of a building automation and control system, to a mesh network of network-capable devices. A cloud-based server system works in concert with an installing device, such as a smartphone or tablet, to apply the relevant configuration of scenarios and spaces, as defined in the design configuration during a design phase, to each mesh node in the mesh network. The commissioning system first transforms the defined scenarios and spaces, which essentially represent a logical configuration of the building automation and control system, into a network-centric configuration. Then, the system decomposes the network-centric configuration into a physical configuration of each mesh node, resulting in a set of parameters for each mesh node.

    Abstract: The method is aimed at providing secure multicast communication between a plurality of devices forming a cluster of devices connected to one another by a local network. The method provides for electing a key distribution device and generating a group encryption key in said key distribution device. A secure communication channel is then established between the key distribution device and each device of a group of devices to be connected to the cluster. The group encryption key is transmitted from the key distribution device to the devices to be connected to the cluster and stored thereby. When all devices of the cluster have received the group encryption key, multicast communication among the devices of the cluster can start.

  • Patent number: 11550574
    Abstract: Apparatuses and methods of operating such apparatuses are disclosed. Vector processing circuitry performs data processing in multiple parallel processing lanes, wherein the data processing is performed in a subset of the multiple parallel processing lanes determined by bit values of a vector predicate which are set. Predicate monitoring circuitry is responsive to the vector predicate to generate a predicate summary value in dependence on the bit values of the vector predicate. A first value of the predicate summary value indicates that a sparse condition is true for the vector predicate, the sparse condition being true when the bit values of the vector predicate comprise a set bit corresponding to a vector element at a higher index immediately followed by a non-set bit corresponding to a vector element at a lower index. A second value of the predicate summary value indicates that the sparse condition is not true for the vector predicate. Improved predicate controlled vector processing is thus supported.

  • Patent number: 10996941
    Abstract: A system enables initiation of request driven peak-hour builds to override “off-peak” patching schedules for updating server applications. An “off-peak” patching schedule is generated to minimize disruption from installing builds of patches. Notwithstanding the “off-peak” patching schedule, a tenant administrator initiates request driven peak-hour builds when some performance failure occurs during peak business hours. For example, the tenant administrator may generate a service request that includes incident data that is usable to identify and/or develop a particular patch for resolving the performance failure. Based on the service request, the “off-peak” patching schedule is overridden to expedite an out-of-sequence installation of a particular patch. In this way, a tenant administrator that becomes aware that some performance failure is disrupting information workers during a peak usage time-range (e.g.

  • Patent number: 10992382
    Abstract: Particular embodiments use the segmented bandwidth in downstream channels and upstream channels to manage a narrowcast service for subscribers. Particular embodiments include a channel manager that can process the signal from the headend to down-convert and filter narrowcast services that are sent in one or more of the downstream channels. Also, in the upstream direction, the channel manager can up-convert and stack narrowcast signals for sending to the headend. Further, in one embodiment, the narrowcast service may be provided using visible light communication (e.g., Li-Fi). Using visible light communication may overcome the last connection restrictions described in the background, such as end to end optical connections may be used. Further, using visible light communication may not interfere with other Wi-Fi links in the subscriber premises, such as existing MoCA connections, and may actually enhance the service at the subscriber premises.

  • Patent number: 10939160
    Abstract: A fast change method for a digital video broadcasting (DVB) channel. A fast channel change (FCC) server is introduced into an existing DVB system architecture, and a unicast transport stream is fast sent to a user equipment in a manner of unicast of the FCC server assisting broadcast. A transport stream (TS) stream and a Real-time Transport Protocol (RTP) stream are synchronized by comparing presentation time stamp (PTS) values of TS streams on a DVB side and an FCC side. In this way, it is ensured that the user equipment fast displays an image, channel change time is reduced, a channel change speed is increased, and user experience is improved.

  • Patent number: 10757013
    Abstract: A computer system splits data to be transmitted into a plurality of reliable connections which are multiplexed through a smaller number of unacknowledged connections, such as connections that do not require acknowledgment and which may be VPN tunnels. A receiver then demultiplexes data received to obtain data flows over the reliable connections and transmits separate acknowledgements for each reliable connection. The computer system demultiplexes the acknowledgments and provides them to the corresponding reliable connections, which then retransmit any unacknowledged data. Delivery controllers executing on the computer system may be coupled to corresponding controllers executing on the receiver, with traffic between the delivery controllers (payload and acknowledgments) being multiplexed over one or more unacknowledged connections. In some embodiments, acknowledgments may be transmitted over a connection that is not multiplexed over the unacknowledged connections.

    Abstract: Certain embodiments described herein are generally directed to determining the spans of logical entities in a logical network using a graph theoretic method. For example, in some embodiments, a configuration of the logical network is represented as a directed graph with labeled edges. The span of any logical entity in the logical network may then be computed based on the directed graph of the logical network. For example, for a given entity represented by a given node, the set of nodes that can be reached from the given node via span-depends-on edges only may be computed and referred to as the span base of the given node. Further, the set of all managed forwarding elements reachable from each node of the span base of the given node via contains edges only is the span for the given entity.
