Abstract
Systems and methods are provided for receivers of digital broadband broadcast signals to determine a time of delivery and a version of a particular signaling table. The receiver is able to determine whether an update of the signaling table is needed based on factors such as whether the update applies (e.g., a DVB-H specific change for a mobile terminal in a DVB-H network). The receiver may power down while awaiting delivery of the signaling table (or utilize the radio for other purposes), powering back up in time to receive the signaling table.
