    摘要: A tangible computer readable medium includes instructions executable by a processor to cause the processor to communicate with a multicast alert server to receive a multicast emergency alert message via a multicast-enabled network of an Internet Protocol television system. The multicast emergency alert message includes data related to a location code and data related to a set-top box action. The computer program further includes instructions to execute the set-top box action when the location code matches location information stored at a set-top box device.
