摘要:
A hierarchical publish/subscribe network is employed to produce and distribute special effects to users to complement displayed video information. A top level broker in the network receives a plurality of data streams corresponding to a respective plurality of primary special. A service provider makes a subscription request for one of said primary special effects and receives the corresponding selected data stream. The selected data stream is transformed into at least one further data stream, corresponding to a further special effect. The further data stream is published to a lower level broker associated with the service provider. In response to a user subscription request for the further special effect, the lower level broker publishes the further data stream to a user interface for presentation to the user in association with the displayed video information.

A publish/subscribe interface is used to enable a non-publish/subscribe first system (such as an IP network device) to obtain status information about a publish/subscribe device that cannot be pinged by the first system. The first system sends a status request to a domain name server associated with a system known to include the publish/subscribe device. The status request includes a domain name for the publish/subscribe device. Topic space maintained by a message broker in the publish/subscribe system includes status topics associated with publish/subscribe devices. The status topics contents reflect the current availability of the associated publish/subscribe device. The domain name is mapped to a status topic associated to the publish/subscribe device identified in the status request and the contents of that status topic are retrieved. If the contents have a first value, a “good” IP address is returned to the first system. If the contents have the second value, a “bad” IP address is returned. The return address is used in ping messages. If the ping operation succeeds, it is concluded the publish/subscribe device is online. If the ping operation fails, it is concluded that the publish/subscribe device is off-line.

For managing the retention of publications in a publish/subscribe system, a publisher sends a new publication to a publish/subscribe broker with an indication of whether the new publication should be retained in association with a previous retained publication. The publish/subscribe broker responds to such indications by retaining the new publication with the previous retained publication. The contents or ‘payload’ of the new published message may be appended to a previous retained message, resulting in a single retained message that contains information from multiple published messages.

Accesses to locally-relevant and contextually-relevant services information within a mobile communications environment are enabled. The solutions include an improved location determination in which a first mobile communications device processes location information broadcast by other devices via short-range wireless signals to determine its approximate location. The described solutions include a context-based selection of the most relevant of a set of locally-available services, including filtering services according to whether the first mobile device is currently moving and filtering according to a personal profile of the device user.

A method and system are for conferencing by exchanging conference communications between two or more participants includes publishing a conference communication to a message broker and subscribing to conference communications at a message broker. A subscription topic specifies one or more type or source of the communication. A conference communication may be one of a text input, transcribed text, audio input, synthesized audio speech, or video input including real or animated images. The method and system of conferencing using publish/subscribe communications allows participants with different communication needs to be accommodated in a flexible manner.

A method for republication of published messages includes receiving a published message on a topic from a publisher, storing the published message as an appended retained message, republishing the appended retained message on a history topic, receiving a request from a subscriber to view at least a portion of the appended retained message, and transmitting the republished message to a subscriber subscribing to the topic after the published message has been published via the history topic.

An identification method and system. The method includes receiving by a computing system from a first entity, first data indicating that an electronic device is missing. The computing system receives from a transaction device reader, second data comprising first identification information associated with the electronic device and third data comprising second identification information associated with a second entity and a transaction device belonging to the second entity. The computing system transmits notification data indicating that the electronic device, the second entity, and the transaction device are located within a specified vicinity of the transaction device reader. The computing system receives log data associated with the second entity and fourth data associated with missing electronic devices. The computing system compares the fourth data to the log data and generates results data to determine if the second entity is associated the missing electronic devices or the electronic device.
