Abstract:
1. A method of transporting a set of data objects over a network for reception by a receiver, comprising: obtaining the set of data objects at a server; separating each data object into one or more data packets; providing the one or more data packets for each object to a transmitter; providing receiver control data to the transmitter, the receiver control data including a value for a listener interval that represents a maximum period over which the receiver may be powered down or off; operating the transmitter to cause transmission of the receiver control data over the network for reception by the receiver; and operating the transmitter to cause transmission of the data packets over the network for reception by the receiver, wherein the transmitter is operated such that if the receiver is powered down or off for a time period less than the listener interval, then the receiver is able to receive a set of the one or more data packets such that each data object can be reassembled from the received set of the one or more data packets, wherein the value for the listener interval is determined based on one or more of a desired maximum notification time for new objects for an existing listener, a maximum total number of objects to be available to a listener at one time, an expected average and maximum size of the objects, a datacast bandwidth available to the application, or a desired outage victim coverage time that specifies a limit for reception outage durations such that the receiver still has coverage with respect to the transport of the set of data objects over the network.
