Methods of delivering IP video content to CPE devices over a network are provided. Customer content-of-interest information is collected from the CPE devices. When a request for an item of content from a requesting one of the CPE devices is received, a determination is made as to whether the requested item of content is of interest to at least a pre-determined minimum number of other CPE devices on the network via analysis of the collected content-of-interest information. The item of content may be multicast over the network if the item of content is of interest to at least the pre-determined minimum number of CPE devices. Alternatively, content indicated as being of interest by at least the pre-determined number of CPE devices may be scheduled for multicast at a low utilization time of the network or at a low priority level. A system for preforming the above methods is disclosed.
