  • Patent number: 10771146
    Abstract: Concepts and technologies disclosed herein are directed to providing redundancy for satellite uplink facilities using software-defined networking (“SDN”). According to one aspect disclosed herein, a satellite network system can include a video collection facility (“VCF”), a remote uplink facility (“RUF”), and a diverse uplink facility (“DUF”) in direct communication with a core network. An SDN controller that operates in an SDN network that provides logical SDN links to the VCF, the RUF, the DUF, and the core network. The SDN controller can track a site configuration of the RUF. The SDN controller can detect that the RUF has been downed due to an adverse event such as inclement weather. The SDN controller can obtain the site configuration of the RUF. The SDN controller can cause a redundant remote uplink facility (“RRUF”) to be instantiated with the site configuration of the RUF.

  • Patent number: 9510060
    Abstract: A system, apparatus, and method provide the ability to process media content streams. A primary and backup multiplexer are each configured to receive and multiplex multiple video streams to output IP multicast streams with unique unicast addresses. A primary and backup uniform transport processing system (UTPS) join the IP multicast streams and output each stream using a unique multicast group. Multiple virtual local area networks (VLANs) separate the joins of the primary UTPS from the joins of the backup UTPS. Primary and backup modulators join the IP multicast streams output from the primary or backup UTPS and convert the joined stream to radio frequency for uplink to a broadcast distribution network.

  • Patent number: 9137302
    Abstract: Systems and methods for content delivery are disclosed. A content delivery system in accordance with one or more embodiments of the present invention comprises a plurality of content delivery networks, and at least one network selector, wherein the at least one network selector analyzes a content delivery request, determines which content delivery networks in the plurality of content delivery networks are suitable for fulfilling the content delivery request, and selects one of the suitable content delivery networks to fulfill the content delivery request.

  • Patent number: 8885491
    Abstract: A method and system for communicating a conditional access signal through a network includes a source segment generating a first conditional access packet signal comprising a first header having a first destination identifier with a first format. The system also includes a first routing server associated with the source segment generating a second header with a second destination identifier having a second format different than the first format and replacing the first header with the second header. The system also includes a second routing server in communication with the first routing server through the network. The second routing server replaces the second header with a third header having a third destination identifier having the first format to form a third conditional access packet signal. A plurality of receiving devices receive the third conditional access packet signal.

  • Patent number: 8509056
    Abstract: A multi-ring IP multicast network is implemented with “N” instances of an Interior Gateway Protocol (IGP). Each IGP instance is autonomously configured on a different ring network to provide service separation between ring networks. Each IGP instance announces the one or more sources that are mapped on the associated ring network. Each source is announced in one and only one IGP instance so that the source is mapped on one and only one ring network. An “N+1” instance of the IGP is implemented on the core routers that are connected to receivers to merge and redistribute the “N” distinct instances of the IGP to the distribution and access routers between the core router and receiver. This effectively merges the N IGP instances at each node so that the multi-ring network appears as a virtual single-ring network with a single IGP instance allowing each of the receivers access to any source connected to the network.
