An affiliate site commands the central site to construct a unique
broadcast event log through the affiliate site's command browser. The
sequenced data stream of broadcast content is combined with a digital
artifact inserted into the digitized broadcast video and/or audio content
immediately prior to the data transmission process. Transmission to the
affiliate site is accomplished utilizing Internet Protocol. Upon
reception at the destination, the commercial advertising or prepared
program content is input to the affiliate site's system, routed to the
broadcast production system, and in turn, processed by the broadcast
transmission site, where it is converted from a digital to an analog
signal, and transmitted electromagnetically in the radio frequency
spectrum by the broadcast transmitter.
