Abstract

The invention discloses a method for sending emergency broadcasts. The method for sending the emergency broadcasts comprises the steps of inquiring whether emergency broadcast information exists in a network information table (NIT), continuing to judge whether the edition number of the emergency broadcast information is updated or not if the emergency broadcast information exists in the NIT, reading the emergency broadcast information if the edition number of the emergency broadcast information is updated, storing the read emergency broadcast information in an emergency broadcast list according to a priority sequence, and broadcasting the emergency broadcast information in the emergency broadcast information list according to the priority sequence. The invention further discloses a digital receiving terminal for sending the emergency broadcasts. Through the adoption of the method and the digital receiving terminal for sending the emergency broadcasts, the emergency broadcasts can be played according to the priority sequence when the emergency broadcasts arise, the searching time of the emergency broadcasts is reduced, playing efficiency is improved, and the emergency broadcasts can be sent to a user in time.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a method for sending emergency broadcast and a digital receiving terminal. Background technique [0002] Emergency broadcasting refers to the provision of a fast and efficient information transmission channel in the event of major natural disasters, emergencies, public health and social security and other sudden public crises, so as to transmit disaster news or the possible hazards caused by disasters at the first time.
