Abstract
A system is provided for coordinating the presentation of program content received from a first network and a second network independent from the first network. The system uses heartbeat messages typically transmitted along communication paths to monitor the operation of the communications paths to transmit information necessary for stream switching to alternate programming or alternate sources of the same programming.
