    Abstract: A communication system provides for automated detection, and resolution, of focus hunt. A server determines whether a predetermined number of blur metric transition (BMT) cycles, associated with a video stream, have occurred within a predetermined period of time or number of frames. In response to determining that the predetermined number of BMT cycles have occurred, the server determines that focus hunt has occurred. A BMT occurs when first and second blur metrics, determined for first and second video frames, transition from being greater than a blur metric threshold to being less than the threshold, or vice versa. In turn, a BMT cycle occurs when a BMT, of a first BMT and a second BMT, comprises a transition of blur metrics from less than the threshold to greater than the threshold and the other BMT comprises a transition of blur metrics from greater than the threshold to less than the threshold.

    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 communication system is provided that analyzes event-related media by correlating various media content based on the media being time-wise proximate to each other. Thereby, the communication system provides an informational tool for law enforcement agencies to correlate different media that all relate to a same event, such as subject matter media with related discussion media. For example, the subject matter media may comprise video, video stills, biometrics, sensor data, Automatic Vehicle Location (AVL) data, pictures, BOLO (Be On the LookOut) bulletins, and the like, while the related discussion media may comprise Push-to-Talk talkbursts, telephone conversations, Instant Messaging (IM), emails, and other forms of discussion media. By correlating such media, the communication system facilitates event or incident reconstruction by providing related media together when providing event or incident playback.

    Abstract: A method and apparatus for multicasting data streams in a wireless radio communication system are provided. A server assigns a plurality of data streams amongst RF resources. One or more points-of-access of the wireless radio communication system are operable to transmit each RF resource to mobile communication devices. Responsive to a request from a mobile communication device for a selected one of the plurality of data streams, the server identifies the points-of-access that have not been assigned, and hence cannot transmit, the RF resource to which the selected data stream is assigned. An access controller instructs those points-of-access to deny association to the mobile communication device. The server then multicasts the selected data stream to the mobile communication device through one of the remaining points-of-access that can transmit the selected RF resource.
