摘要： A system and method for producing and receiving interactive broadcasting having a broadcast signal with a hypermedia channel and a logical multicast data channel. The logical multicast data channel has a broadcast signal markup stream (BSMS). The system users have a receiver with an interactivity module and a communication module. The BSMS allows user selectable objects to be displayed to users of the system. BSMS objects can be generated by combining speech recognition, language (and optionally video) processing, and keyword searches. By selecting objects various information relating to those objects may be displayed to users. A portion of the logical multicast channel may be employed to provide interactivity between users. A variation eliminates the BSMS either by employing a markup stream server to provide access links or by generating link content directly in the receiver by the same process.

摘要： A method for establishing and maintaining a wireless ad hoc network comprising backbone nodes which forward packets through the network and non-backbone nodes which are capable of using the network, but do not forward packets. Signaling packets containing one or more protocol support records are periodically generated and transmitted by each node to neighboring nodes and are forwarded through the network by backbone nodes. Non-network nodes are initially selected to become backbone members during a SELECTION process based on an assessment of the node's connectivity relative to its neighbors. Link quality between nodes is monitored and used during an EXPANSION process in which additional non-network nodes may become backbone members. Disconnected backbone segments are interconnected during a CONNECTION process and the network is maintained during a MAINTENANCE process by periodically assessing the value of a backbone node's membership in the backbone. Efficient multicast routing is supported over the backbone by dynamically establishing and maintaining multicast trees. Signaling packets are periodically and frequently generated, thereby facilitating rapid adaptation to network changes. Further, the signaling packets are efficiently forwarded only by backbone nodes, thereby reducing bandwidth associated with establishing and maintaining the network.

摘要： The present invention provides a method and apparatus for extending a zone routing protocol. The invention is configured to provide a robust scalable framework for routing data in wireless ad-hoc networks when unidirectional links 210 are present. When the reverse path from a destination node (the tail) of a unidirectional link 210 to the originating node (the head) of the link is beyond a designated length, the invention is configured to revert to an on-demand search mechanism. The on-demand search mechanism recursively attempts to build a path to the destination 206 by recognizing nodes that have a route to the destination.
