Abstract:
1. A method for delivering digital video programming via a cable system network, the method comprising: receiving at least one digital video programming input stream at a cable system hub; assigning each received input stream to an RF channel for downstream delivery; spanning the assigned RF channels over multiple fiber nodes of the cable system network using the cable system hub; forwarding each input stream over the assigned RF channel for multicast downstream delivery to subscribers; receiving a video stream request sent from a subscriber equipment to an application manager using Packet Cable MultiMedia (PCMM) signaling in a PCMM architecture environment; and the application manager informing the subscriber equipment of a multicast address corresponding to the video stream request, enabling the subscriber equipment to use the multicast address to receive and decode the corresponding input stream that is forwarded over the assigned RF channel as a multicast data stream.
