ABSTRACT:
The present invention describes a method for transmitting high bandwidth network content on a low bandwidth communications channel during off peak hours. According to one embodiment of the present invention, criteria is determined for downloading data from the communications channel and the data is downloaded from the communications channel during off-peak hours based on the determined criteria. According to another embodiment, a method for coordinated multicasts on a network is described. Download requests are received on a server from a plurality of clients on the network and stored on the server for the coordinated multicast. The coordinated multicast is generated at a predetermined time and then broadcast from the server to the plurality of clients at the predetermined time.
