  • Patent number: 7720987
    Abstract: In a digital network that includes a plurality of devices, which include multiple devices that transmit transport streams, a system and method are provided for discovering and mapping the transport streams and the plurality of devices included in the digital network. One such method sends a transport stream map request to a plurality of network devices. The network devices include a plurality of network transport stream sources and a plurality of network transport stream handlers. The method receives a plurality of replies to the transport stream map request. Each reply includes information associated with the respective network device. The method generates a transport stream map based on the received replies. The transport stream map represents a flow of transport streams among the plurality of network devices.

  • Patent number: 7457883
    Abstract: In a digital network that includes a plurality of devices, which include multiple devices that transmit transport streams, a system and method are provided for discovering and mapping the transport streams and the plurality of devices included in the digital network. In the preferred embodiment, the system includes a controller that, among other things, receives network messages from the plurality of devices and determines or assigns transport stream identifiers in the network such that transport stream identifier conflicts do not occur. In the preferred embodiment, the plurality of devices are adapted to respond to a first message by sending a network message to the controller, and the devices are adapted to monitor their received transport stream(s) and respond to changes by sending a second network message to the controller.

  • Publication number: 20030074670
    Abstract: A system and method for providing dynamic network information to devices in a network is disclosed. The network includes a plurality of devices that receive dynamic network information and at least one transport stream. The dynamic network information received by a device of the plurality of devices includes network information related to the transport stream received by the device. In one embodiment, the device uses the received network information to monitor the network and to determine network conditions.
