Synchronous updating of dynamic interactive applications
InactiveUS7222155B1Easily interfaceTelevision system detailsAnalogue secracy/subscription systemsControl signalApplication software
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.

Method and apparatus for periodically delivering an optimal batch broadcast schedule based on distributed client feedback
InactiveUS7055165B2Television system detailsSpecific information broadcast systemsRankingMetadata description
A method and system for periodically deriving an optimal batch broadcast schedule based on client demand feedback data from a distributed set of broadcast clients. The broadcast system includes an operation center that broadcasts meta-data to a plurality of client systems. The meta-data describes a plurality of pieces of content that are in consideration for upcoming broadcasts by the server. Each client receives the broadcasted meta-data from and sends back a set of client demand feedback data to the operations center, wherein the user feedback data reflects a client's interest level in at least a portion of the pieces of content. The feedback data, which typically may include ratings and / or relative rankings, may be user-generated, automatically-generated, or a combination of the two. The system then send a batch of content based on an aggregation of the feedback data in combination with available broadcast bandwidth and broadcast schedule window.

Method and Device for Data Routing and Bandwidth Reservation in Small Scale Distributed Networks
InactiveUS20090147723A1Reduce communication overheadEnergy efficient ICTFrequency-division multiplex detailsBroadcast schedulingNetwork topology
A data routing and / or bandwidth reservation method for small scale distributed network in which each member has a topological view of the whole network. Route selection is performed at a source member and bandwidth reservation is conducted along the selected route. Upon start up or joining the network each member of the network establishes and maintains a list of information for all other devices in the network, which serves as a topological view of the network. To reduce communication overhead during information collection, a priority based broadcast scheduling is adopted. When a device intends to establish a connection with another device it selects a route based on its own preference and current network topology. The device then reserves bandwidth along the selected route. Bandwidth reservation uses a mutually exclusive bandwidth reservation protocol which guarantees only one application can reserve bandwidth at a time.
