Operations of an Advanced Television Systems Committee (ATSC) receiver include receiving an ATSC broadcast signal, the ATSC broadcast signal including signaling characterizing content of a plurality of channels, wherein a dispatch channel includes dispatch messages. The operations include analyzing a low level signaling (LLS) table for the dispatch channel to determine whether a dispatch message has been added to the ATSC broadcast signal and selecting a mode of operation based on the analyzing. The modes of operation include a sleep mode if a version of the LLS table for the dispatch channel has not changed and a dispatch mode in response to detecting a change in the version of the LLS table. In the dispatch mode, dispatch messages not destined for the ATSC receiver are ignored and an emergency operation is actuated in response determining that a particular dispatch message is destined for the ATSC receiver.
