    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 client-based method, a server-based method, and a client device enable streaming of multiple video streams utilizing standardized methods while ensuring the multiple video streams share bandwidth over a single, variable connection such as a wireless connection. These methods and device enable an equitably share of bandwidth across multiple video streams sharing a same physical medium. Further, these methods and device can enable selective prioritization of any of the multiple streams.

    Abstract: A method and apparatus for delayed talk-back behavior in a communication device associated with a Push-to-Talk (PTT) system include presenting talk-burst audio to a user at the communication device, wherein the talk-burst audio is delayed; receiving a PTT request from the user; determining a delay time interval between the PTT request and a time when the talk-burst audio was originated; and performing an action for the PTT request based on the delay time interval, wherein the time interval is utilized to determine if the action is a standard PTT response or an alternative PTT response to the PTT request.

    Abstract: A communication system synchronizes subscriptions between a user terminal (UT) and a Subscription Service Host (SSH). The UT conveys, to the SSH, multiple subscription messages associated with a Watcher that each initiates a subscription associated with the Watcher and requests watched entity status information. The UT starts a timer and, in response to an expiration of the timer, conveys a subscription information consolidated status update (SICSU) request to the SSH that requests a consolidated status update of all subscriptions associated with the Watcher. In response, the UT receives an SICSU notification comprising a first one or more SICSU values that indicate a status of multiple subscriptions associated with the Watcher, determines a corresponding second one or more SICSU values based on its own list, compares the first SICSU values to the second SICSU values, and determines whether the UT is out of synchronization with the SSH based on the comparison.

    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: A method and vehicle-based communication system are provided that control a remote microphone by determining that one or more of the remote microphone and a user of the remote microphone is in a field of view (FOV) of a video camera and, in response, instructing the remote microphone to configure itself to receive ambient audio. In various embodiments, the remote microphone may configure itself, or be explicitly instructed to configure itself, to receive ambient audio by adjusting one or more of a beam forming or omni-directional pattern, potentially including noise cancellation algorithms to facilitate reception of ambient audio in contrast to user directed audio. When the one or more of the remote microphone and a user of the remote microphone no longer is in a FOV of the video camera, the method and vehicle-based communication system may instruct the remote microphone to reconfigure itself to receive user directed audio.

    Abstract: A digital image capture device streams captured images (e.g. low-resolution images) to a remote viewer terminal, along with image identifiers and/or device position information. The remote viewer terminal displays the images for viewing by a remote viewer. The remote viewer provides inputs to a user interface, which indicate a direction of desired movement of the image capture device, and/or that the remote viewer wants new images (e.g. high-resolution images) to be captured at a desired position. The user interface inputs are translated into requests, which are transmitted to the image capture device. The image capture device provides movement prompts that direct a device operator to move the device in a requested direction or toward a requested position. When a position of the device corresponds to a requested image capture position, the image capture device captures one or more new images, and transmits the new images.

    Abstract: Primary and/or secondary communication groups can be assigned to users with communication devices arranged in a hierarchy (FIG. 4). A set of humans are assigned to a role in a role-based hierarchy. A communication device (404) is assigned to the set of humans for communication over a network. One or more secondary communication groups are determined for the communication device (120). The one or more determined secondary communication groups are primary communication groups of other devices used by one or more other humans assigned roles in the role-based hierarchy. Secondary communication group settings are programmed for the communication device (124), where the group settings are consistent with the determined secondary communication groups.
