Architecture and provisioning tools for managed multicast virtual private LAN trees

Methods, tools, and a multicast connectivity architecture are provided for provisioning bundled high bandwidth multi-channel multimedia broadcast services over a packet switched communications network. Multicast group membership join/prune requests generated by the destination network nodes are processed on edge. Multicast tree connectivity in the core of the communications network is static and centrally provisioned based on multicast group member edge network nodes associated with subscribers, while dynamic multicasting techniques are employed over the distribution portion of the service provider's communications network to deliver requested content to each destination network node. The methods and tools compute multicast trees, configure on-tree branching network nodes, and establish Virtual Private LAN network overlays for channel bundles to convey multi-channel content in the core of the managed communications network between edge network nodes. Centralized multicast tree provisioning enables the use of efficient multicast tree topologies, while VPLS packet transport provides interoperability between disparate Layer-2 packet transport technologies employed in different portions of the communications network.

Digital broadcasting system and data processing method

The present invention provides a method of processing data in digital broadcasting system. The method includes receiving a broadcast signal including mobile broadcast service data and main broadcast service data, wherein the mobile broadcast service data configures a data group, wherein the data group is divided into a plurality of regions, wherein N number of known data sequences are inserted in some regions among the plurality of regions, and wherein a transmission parameter is inserted between a first known data sequence and a second known data sequence, among the N number of known data sequences, detecting the transmission parameter from the mobile broadcast service data, symbol-decoding the received broadcast signal included in the mobile broadcast service data in block units, based upon the detected transmission parameter, extracting a video data from the mobile broadcast service data, parsing the extracted video data by a NAL unit, obtaining NAL unit type information from parsed NAL header, obtaining extension information of a NAL header, when data of a current NAL unit indicates scalable video coded data according to the NAL unit type information, and decoding the video data using the extension information of the NAL header, wherein the extension information of the NAL header includes at least one of temporal level information, quality level information, information indicating whether inter-layer prediction is used, and dependency information of the NAL unit.

Automatic control of broadcast and execution of interactive applications to maintain synchronous operation with broadcast programs

An automation server interfaces with broadcast scheduling systems of various types to automatically synchronize the behavior of interactive applications relative to various broadcast programs, such as television shows and commercials, so as to maintain the appropriate interactive application for whatever broadcast program is airing. This allows for television shows which have an associated interactive application, but which are segmented by commercials (which may have their own interactive applications) to have their interactive application displayed while the television show in on, but not during commercials, while maintaining any state information that has been created during execution of the interactive application. The automation server includes multiple channel interfaces, each having a translator and an event manager. The translator translates native control signals from the scheduling system into a fixed set of atomic commands which represent the lifecycle behavior of a broadcast program. The event manager receives these atomic commands and uses them to determine the appropriate state for any interactive application that is associated with the broadcast program. The event manager transmits commands to a broadcast server which directly manages the interactive applications by transmitting code, data, and commands to broadcast receivers that controls the execution of the interactive applications in response to the event manager's commands.
