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).
