LOCATION SPECIFIC EVENT BROADCASTING

摘要

Applications in a broadcast environment distribute events in real-time to a large number of receivers within specified geographic locations while efficiently sharing bandwidth resources with other applications using the same broadcast network. Applications need not be aware of the other applications sharing the resources, nor of the methods, protocols, and other mechanisms used to actually broadcast the data over the broadcast medium. Server-side applications that serve data, send notifications, or distribute events to specific locations within the network use a broadcast location manager. Client applications that receive such data, notifications, or events use a client location filter to obtain events that are relevant based on the location of the device. The broadcast location manager and client location filter work together to reliably and efficiently transmit data, notifications, and events to specific locations over the broadcast network for all applications involved.

主权项

1. A method for filtering events, the method comprising:
receiving a plurality of events at a client device, wherein at least one event is associated with a location tag that identifies a physical location in a network, the physical location being smaller than an area served by the network; determining the location of the client device; and forwarding the event to an application in the client device if the location of the client device is within the physical location identified by the location tag.
