A method and system including a broadcast and a local information source, a headend, and a link are described for providing local information to a user device. A broadcast information stream generated at a first data rate is received at the headend. Local information packets are inserted at the headend into the broadcast information stream forming a combined information stream which is transmitted to the user device at a different data rate.
