Method and system for replicating a video stream onto separate QAM downstream channels
First Claim
1. A method for transporting a digitally encoded content stream from a content device over a wide area network through one or more distribution devices to a plurality of user devices, comprising:
- associating an endpoint identifier with a termination point of the distribution device(s);
associating the termination point with a plurality of subscriber-channels for delivering the content stream to a plurality of user devices;
transmitting the stream to the termination point of the distribution device(s) associated with the endpoint identifier; and
replicating at the distribution device(s) the transmitted stream into a number of streams corresponding to the plurality of user devices.

Abstract
A system transports a single video stream from a video server over a WAN to a replicator at a specified IP address. The specified address may correspond to a RTP or UDP/IP address of an endpoint or port. A table at the replicator associates a plurality of downstream QAM channel frequencies with the specified address and the replicator creates as many copies of the stream as there are QAM channels associated with the IP address. The copies are forwarded to each of the QAM modulators that are tuned to one of the frequencies that are associated with the IP address. Grooming is done at each of the QAM modulators according to rules that correspond to the channel.
