    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 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: Public safety user equipment (PS UE) that establishes a first wireless communication channel over a primary network to at least one multimedia multicast or broadcast service management entity and establishes one or more alternative wireless communication channels over one or more alternative networks (310). The public safety user equipment receives at least one multimedia multicast or broadcast service message over the first wireless communication channel (320), Then, the PS UE extracts data contained in the multimedia multicast or broadcast service message and storing the data in a local cache (330). The PS UE receives a cache request from the one or more user equipment over one or more alternative wireless communication channels (340) and then the PS UE transmits the stored data to the one or more PS user equipment (350).

    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 for uploading data is provided herein. During operation vehicles in the field will upload their digital multimedia evidence (DME) to a mobile/intermediary upload point(s). These mobile/intermediary upload points preferably comprise computers existing in other vehicles that are not currently connected to a central repository. A mobile recorder (mDVR) will choose a particular mobile/intermediary upload point(s) based on a probability that the mobile upload point(s) will return to a connected upload point to upload the transferred DME.

    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.
