Abstract
The present invention provides a method for object retransmission in an asynchronous environment without a continuous network connection in a digital media distributor (DMD) system. The method includes receiving objects in a receiver from a central site, generating a response document in the receiver, and sending the response document asynchronously to the central site. The received response documents are then utilized in the central site to determine which object to retransmit to the receiver. In another aspect of the present invention, the central site manages the inventory of objects in the receiver by instructing the receiver to delete objects not needed.
