SYSTEM AND METHOD FOR TERRESTRIAL BROADCAST OF EMERGENCY ALERTS

摘要

Systems and methods are disclosed for broadcasting and receiving a terrestrial broadcast signal containing emergency alert information in machine-readable format. The method includes the steps of scanning a Transport Stream associated with the terrestrial broadcast signal. The Transport Stream contains one or more Transport Stream packets and a plurality of tables, which are parsed to identify a channel having a type specified as containing emergency alert information. An MPEG-2 program having said emergency alert information may then be acquired for delivery through a terrestrial broadcast receiver.
