Abstract

A system for distributing digital content includes two or more digital. content sources. Each source has a separate session manager that is distinct from other session managers associated with other digital content sources. The system further includes at least one set of network resources that receive digital content from the two or more digital content sources, modulate the digital content onto a carrier signal suitable for transmission over an access network, and transmit the carrier signal over the access network. The system also includes a receiving device for terminating the carrier signal. The receiving device generates a digital content stream corresponding to the digital content from the two or more digital content sources. The system further includes a policy server for allocating bandwidth of the network resources to the digital content sources, and for monitoring a utilization state of the network resources.
