Abstract
A method, computer readable medium, and system for advertisement and content distribution are provided. Supplementary content is synchronized with advertisement slots, or commercial intervals, of a program stream and distributed via separate multicast group addresses. The program content is distributed via an alternative multicast group address during commercial intervals. Ports associated with respective users are mapped or otherwise associated with multiple multicast group addresses in a forwarding table thereby allowing distribution of supplementary content, or alternatively the program content, during commercial intervals.
