1. A method to monitor media, the method comprising: processing, via a processor, historical metering data provided by a meter monitoring media presented at a monitored site to predict media exposure to occur at the monitored site during a future monitoring interval; obtaining reference signatures representative of reference media predicted to be presented at the monitored site during the future monitoring interval; and providing the reference signatures to the meter prior to the future monitoring interval to cache at the meter to perform media monitoring during the future monitoring interval.
