Abstract: A method and system enable determining one or more delays associated with an internet protocol (IP) camera. The method includes issuing a control command from a device to the IP camera. A change is then detected in one or more pixels in video frames as a result of the control command being executed by the IP camera. One or more delays associated with the IP camera are then determined by recording and comparing two or more of the following: a command time; a feedback time; and a capture time.

Abstract: An embodiment takes the form of a process that includes transmitting video frames to a receiving device during a first transmission period of one or more time slots of a half-duplex air interface, and receiving feedback messaging from the receiving device during a feedback period of one or more time slots of the half-duplex air interface. The process further includes suspending, after the first transmission period, transmission of video frames for a suspension period of one or more time slots of the half-duplex air interface, and after the feedback period and after the suspension period, transmitting one or more recovery frames to the receiving device during a recovery period of one or more time slots of the half-duplex air interface. The one or more recovery frames collectively include inter-coded macroblock data and/or intra-coded macroblock data.

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 client entity generates a subscription to a presentity that includes a sequence of events which define a trigger that controls when a presence server sends a notification to the client entity; and the subscription further indicates a time period parameter for the sequence of events. Upon receiving the subscription, the presence server receives and monitors presence information based on the indicated time period parameter to detect an occurrence of the sequence of events, and sends the notification to the client entity when the presence information satisfies the trigger.

Abstract: A media server and method of operation of a media server in a wireless communication system are provided. The media server receives media streams from mobile communication devices in the wireless communication system, and routes the media streams sequentially to a packet header compression encoder. A processor of the media server is configured to receive a first media stream from a first mobile communication device, receive a request from a second mobile communication device to transmit a second media stream to the media server, and transmit data derived from an RTP header of the first media stream to the second mobile communication device. The second mobile communication device is enabled to commence transmission of the second transmitted media stream using the data derived from the RTP header. The wireless communication system may be a PTT wireless communication system or a group video wireless communication system.

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.

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.

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 method and apparatus are provided for capturing video so that compression and quality can be optimized. During operation, a video recording system will employ a learning algorithm to determine periods when a light bar is on, or active. Reference Intra frames are then stored and used for the subsequent creation of predictive frames. More particularly, at least a first Intra frame is stored and used for creating predictive frames during periods of light bar activity. In a similar manner, a second Intra frame is stored and used for creating predictive frames during periods of light bar inactivity. By learning the light bar pattern, Intra frames can be more intelligently selected, resulting in optimized compression and quality.
