Abstract
A server-client system or architecture that allows datacast applications to reliably transport data objects from a network server over a unidirectional packet network (“datacast network”) to one or more clients, each of which may be listening to the packet stream at different times. The invention allows the clients to listen intermittently to the datacast, yet still receive all of the data objects published by the server in a timely manner, and in a way that is more optimal in terms of client resource use. This ensures that listening clients can receive a complete set of the data objects broadcast while being able to conserve client processing and power resources by not requiring continuous listening by the client to the datacast.
