  • Patent number: 8990324
    Abstract: A method of translating a source message having a first set of defined word fields in a source message format, into a sink message having a second set of defined word fields in a desired sink message format. A common message format (CMF) is defined to have a third set of word fields that corresponds to a union of the first and the second sets of word fields. For any given word field in the third set of word fields in the CMF, information contained in a corresponding word field in the source message, if any, is mapped to the given word field in the CMF. For any given word field in the second set of word fields in the sink message format, information contained in a corresponding word field of the CMF, if any, is mapped to the given word field in the sink message.

  • Patent number: 8842663
    Abstract: A system for enabling interoperability among various kinds of communications equipment and information transmission formats on the battlefield or during tactical missions. The system includes a multi-message translator (MMT) for translating a source text message having a first set of word fields defined according to a source message format, into a sink message having a second set of word fields defined according to a sink message format. The system also includes a voice bridging gateway (VBG) for bridging multiple voice communication networks having associated transmission protocols that are incompatible with one another. Dismounted soldiers obtain location based services including geo-referenced maps, and tactical communications including voice and text messaging, using smart phones or other lightweight COTS client devices that link through a personal networking node (PNN) server to one or both of the MMT and the VBG.

  • Patent number: 8688107
    Abstract: Each of a number of gateway network radios operates with a transmission protocol of an associated one of plural incompatible communication networks. Each network radio has an audio terminal for producing first audio signals detected from transmissions of user radios in its associated network, and a microphone terminal for receiving second audio signals for transmission to the user radios. A voice bridging gateway server has multiple ports each corresponding to one of the networks for coupling to the network radio associated with the one network. Each port receives the first audio signals from the audio terminal of the associated network radio, and produces the second audio signals for applying to the microphone terminal of the network radio. The server implements a private branch exchange application whereby user radios in a given communication network can be voice bridged with user radios in a selected one or more of the other networks.

  • Publication number: 20120231787
    Abstract: A method of bridging radio communication networks having incompatible transmission protocols. Network radios each configured for the protocol of an associated network are provided. An audio terminal of each radio outputs analog audio signals that the radio detects over its network, and a microphone terminal of the radio inputs analog audio signals for transmission over the network. The signals from the audio terminal of a given network radio are converted into digital audio signals and input to a selected port of a server that implements a PBX application for bridging the networks selectively with one another. The digital audio signals input to the selected port are converted into corresponding analog audio signals and applied to the microphone terminal of each network radio with which the given network radio is to be bridged. Telephone devices having access to a PSTN can also be bridged with a network by the PBX application.

  • Patent number: 5907366
    Abstract: A method and device for inserting data onto one or more lines of one or more vertical blanking intervals of a television video signal, and in particular a television signal conforming to the NTSC (National Television Standards Committee) format.

  • Patent number: 5892535
    Abstract: A flexible and configurable system for distributing media (or programming) to one or more distribution networks. The system includes a media server, at least one server interface unit, a first communications path coupling the media server and a server interface unit, distribution network interface unit(s), and a second communications path coupling a server interface unit and the distribution network interface unit(s). The media server stores files of encoded (e.g., compressed) media data and files of scheduling information. Each of the distribution network interface unit(s) conditions received media data for transmission over the distribution network(s) which may be analog and/or digital distribution networks.

  • Patent number: 5838678
    Abstract: A method and device for preprocessing streams of encoded data (e.g. compressed in accordance with an MPEG standard) to permit a decoder to decode the streams, back-to-back (i.e., one stream immediately following another), without being reset and without producing video artifacts. The present invention includes verifying that a multiplexed stream complies with an encoding standard and preprocessing packets of the packetized encoded video sequence such that no video artifacts are produced when a video decoder decodes an adjacent encoded video sequence.
