Abstract: A single frequency network [100] includes a main central site [200] and a remote site [300]. The main central site [200] (a) generates a digital symbol based on an input source, (b) receives external reference information from a common source, (c) stores the digital symbol in a local memory buffer [215], (d) adds a time stamp to the digital symbol based on the external reference information, (e) transmits the digital symbol and the time stamp (f) generates an RF signal based on a modulation of a carrier by the digital symbol at a predetermined time according to the time stamp, and (g) broadcast the RF signal. The remote site [300] receives the digital symbol, determines the time stamp, generates the RF signal based on modulation of the carrier by the digital symbol at the predetermined time according to the time stamp, and broadcasts the RF signal.
