Abstract
In an embodiment of the invention the Network Operator (NO) manages the available bandwidth of the digital broadcast network in time-dependent manner. The NO announces the available bandwidth to the datacast operator (DCO) via an interface for a certain period of time. The interface is a data connection intermediator between the NO and the DCO. A network of computing systems couples the NO with the DCO. Advantageously, the network of computing systems comprises Internet. The DCO, which makes use of the NO's bandwidth for distributing electronic media to end-users, reserves some bandwidth for a certain period of time in accordance with the need, which the DCO obtains from a Content Provider (CP). The content is broadcast to the end-user in accordance with a schedule which is based on the bandwidth availability. Thus, the content is multicast via the digital broadcast network which is maintained by the network operator (NO).
