Abstract

A method and apparatus for providing synchronization signals (26) for synchronizing broadcast media (28) and parallel media (32) using a communications network (14). A synchronization server (12) is operably coupled to the communications network (14) and is operably coupled to a broadcast media start time database (24). The synchronization server (12) receives from a user client via the communications network (14) a synchronization request (34). The synchronization server (12) generates synchronization data (26) using the synchronization request (34) and the broadcast media start time database (24). The synchronization server (12) also generates synchronization instructions and the synchronization server transmits to the user client via the communications network (14) the synchronization instructions and the synchronization data (26).
