A method of processes data such as video information. The method includes providing a request from a gateway to an adaptive bit rate server for a unicast adaptive bit rate stream and converting by the gateway the unicast adaptive bit rate stream into one or more multicast adaptive bit rate streams. The gateway is in communication with user equipment having security paired client devices. The method further includes receiving link conditions between the security paired client devices and the user equipment from the user equipment. The method also includes adapting using the gateway the unicast adaptive bit rate stream in response to the link conditions.

A broadcast receiving apparatus and a signal processing method thereof are provided. The broadcast receiving apparatus includes a receiver configured to receive a data stream comprising a plurality of physical layer pipes (PLPs); a demodulator configured to output at least one generic packet corresponding to each of the plurality of PLPs and additional information on the at least one generic packet by demodulating the plurality of PLPs; and a signal processor configured to process the at least one generic packet based on the output additional information.

A centralized communication system (CCS) is disclosed that provides a modular, extendible, and scalable communication system that can exchange information between any information systems or networked devices. Information from a single source device or system can be selectively broadcast to one or more predetermined destination devices and systems rather than broadcast to every device on the network. Information may be filtered and processed at one or more selectable points in the communication flow between systems. In certain embodiments, an incoming message is received from the source device in the native message format using the native protocol of the source device and converted to an internal messaging format for internal handling within the CCS, then converted to the native message format of a receiving system and sent to the receiving system using its native protocol. In certain embodiments, a graphical representation of the topology of the CCS may be provided.

Disclosed herein is an apparatus for receiving a multicast signal. The apparatus may include a multicast gateway configured to receive a multicast signal based on an interface from a multicast server, and a content playback configured to display a multicast service in the multicast signal. Disclosed herein is a method of receiving a multicast signal. The method may include receiving a multicast signal based on an interface from a multicast server, and displaying a multicast service in the multicast signal.

The use of Network Virtualization using Overlays over Layer 3 (NVO3) is a growing trend to address networking issues in data centers that make use of virtualization and cloud computing techniques. Additional considerations may be required to support application-specific multicast traffic in such overlay networks. Systems and methods are provided for an overlay network control function node to allocate one or more overlay network edge nodes to act as a multicast gateway for each network segment. The gateway can distribute multicast traffic to other participating edge nodes in its same network segment, thus reducing network traffic.

First, a packet may be received by a first provider edge device from a first customer edge device locally connected to the first provider edge device. Then the first provider edge device may replicate the packet to a second customer edge device locally connected to the first provider edge device and encapsulate the packet with an address of the first provider edge device. Next, the first provider edge device may transmit the encapsulated packet to a second provider edge device. Then, the second provider edge device may determine from the determined address of the first provider edge device, that the first provider edge device is not locally connected to a third customer edge device. The second provider edge device may then replicate the packet to the third customer edge device in response to determining that the first provider edge device is not locally connected to the third customer edge device.

Embodiments use the principles of self-organizing networks to allocate resources to allow spectrum owners to share spectrum with wireless carriers according to defined license conditions. A spectrum licensee holds the licensing conditions of the spectrum licensed by the spectrum owners. This licensed spectrum is referred to as secondary spectrum. A self-organizing network server requests access to secondary spectrum. The spectrum licensee grants access to the secondary spectrum along with the licensing conditions for access. The self-organizing network server monitors the conditions associated with the license and/or delegates the responsibility for monitoring conditions associated with the license to others. When the license conditions are met, enhanced Node B systems may begin using the secondary spectrum according to the license conditions. When the license conditions are no longer met, enhanced Node B systems discontinue use of the secondary spectrum.

Techniques for bridging communication between multiple networks to facilitate distribution of multicast data are described herein. For example, the techniques may identify a particular node that is able to communicate with each network and instruct the particular node to act as a bridge between the networks. The particular node may forward data from either network to the other network. This may allow data for a multicast group to be distributed to members of the multicast group that are located in separate networks.

For logical multicasting in overlay networks, at a data processing system, an original unicast packet is received from a first component in a first computing node in an overlay network. To cause multicasting in the overlay network the received original unicast packet was unicast by the first computing node only to the data processing system, and a multicast data structure for the overlay network is maintained only by the data processing system, the multicast data structure containing information of each receiver that is configured to receive unicast packets during logical multicasting in the overlay network. From a set of subscriber receivers in the multicast data structure, a subset of the subscriber receivers is selected. A copy of the original unicast packet is unicast to each subscriber receiver in the subset.
