Abstract: Multiple cameras are operatively connected over a shared link to a video server on a video network. The cameras are operated to capture a plurality of video streams. Each video stream has intra-frames and predictive frames that are sequentially generated timewise apart. A number of the video streams that transmit over the shared link on the network is identified. A number of intra-frames that are generated substantially simultaneously in the identified video streams is also identified. The identified intra-frames in the video streams are offset in time to minimize video artifacts from being present in the video streams being transmitted over the shared link.

Abstract: A video tagging method, a video analytics method, and a Computer Assisted Dispatch (CAD) system use incident reports for video tagging and searching. A CAD system is integrated with field-based video surveillance systems to aid in searching video content and subsequent tagging of the video content. The systems and methods can include extracting keywords from a CAD incident report and creating a small, focused, and incident-specific dictionary on which to perform video searching in real-time. The small, focused, and incident-specific dictionary increases tagging accuracy and reduces tagging processing time in the context of video analytics. Further, a multi-pass approach in real-time continually updates and disseminates to video cameras of interest the small, focused, and incident-specific dictionary as the CAD incident report is updated and as the incident of interest plays out.

Abstract: An intermediary function receives a reservation request for a desired throughput from the sourcing device, and determines a set of bearers whose aggregate throughput approximates the desired throughput. The intermediary function requests from at least one access network the set of bearers whose aggregate throughput approximates the desired throughput, and receives from the at least one access network an allocated set of bearers, wherein the allocated set of bearers comprises one or more bearers. The intermediary function informs the sourcing device of an aggregate throughput of the allocated set of bearers, receives user plane data from the sourcing device, and associates the user plane data with the allocated set of bearers in order to transport the user plane data to the receiving device. Subsequent modifications to the allocated set of bearers causes the intermediary function to inform the sourcing device of the modified aggregate throughput of the allocated set of bearers.

Abstract: Some embodiments are directed to methods and apparatuses for enabling voice discussions about a same data content being independently and simultaneously accessed on at least two devices. A server detects when a first device of the at least two devices accesses the data content. The server identifies and reserves an available voice communication group resource. Responsive to detecting that the at least two devices are independently and simultaneously accessing the data content, the server identifies and reserves an available voice communication group resource, and sends a voice group identifier for a reserved voice communication group resource to the at least two devices to allow access to the reserved voice communication group resource.

Abstract: A method includes receiving a frame containing an object of interest and determining a current pixel density of the object of interest. The current pixel density is compared to a minimum pixel density to generate a comparison result and an indication is received of available throughput of a wireless network used to transmit the video. Based on the comparison result and the available throughput, a pixel density compensation method is selected from multiple methods, which include adjusting a zoom feature of a camera used to capture the video and adjusting encoded frame resolution. Using the selected pixel density compensation method, a pixel density compensation parameter is determined to adjust the current pixel density with respect to the minimum pixel density for the object of interest. The pixel density compensation parameter is provided to one or both of the camera or an encoder that sends the video over the wireless network.

Abstract: A method for bearer reservation, maintenance, and use in a communication system is performed by an intermediary function (IF) in the enterprise network. The IF processes a user plane reservation request for a flow of user plane data from a sourcing device, and determines a set of bearers to transport the flow of user plane data. The IF requests from at least one access network the determined set of bearers, and receives from the at least one access network an allocated set of bearers, wherein the allocated set of bearers comprises one or more bearers. The IF receives the flow of user plane data from the sourcing device. The IF receives an indication that at least one of the bearers in the allocated set of bearers is unavailable, and prevents at least a portion of the flow of user plane data from being transmitted over the default bearer.

Abstract: A method and apparatus for granting wireless connection resources for a UE within a communication system is provided herein. During operation, an application requests allocation of wireless communication resources (a bearer reservation) to sustain transmission at a specified bit rate across the communication system via an admission control function. In response to the bearer reservation request, an admission control function calculates a wireless connection efficiency as a function of the requested bit rate and an amount of shared wireless connection resources required to sustain the requested bit rate given the current wireless connection quality associated with the UE. The wireless connection efficiency is then utilized to determine whether or not to admit the bearer reservation request.

Abstract: A video decoder system receives a user request for non-linear decoding of at least one video frame from a video stream encoded using an Intra macroblock refresh process. The request includes a first frame offset corresponding to a user requested first decoding frame within the video stream for commencing the non-linear decoding. The decoder system: determines an Intra-refresh period corresponding to at least one encoded Predictive frame in the video stream during which all macroblocks in the user requested first decoding frame are Intra encoded at least once; determines a second frame offset as a function of the Intra-refresh period and the user requested first frame offset, the second frame offset corresponding to a second decoding frame within the video stream. Finally, the decoder system decodes the video stream starting at the second decoding frame and suppresses the display of the video stream until the first decoding frame.
