Description
Technical Field
The invention relates to the technical field of IT, in particular to a television broadcasting system and a television broadcasting method for emergency broadcast messages.
Background
At present, an emergency broadcast system mainly includes an emergency information source, an emergency broadcast platform, a transmission overlay network, and a receiving terminal. The emergency broadcast platform collects, converges and shares emergency information from an emergency information source, makes an emergency broadcast message according to a standard format, and sends the emergency broadcast message to the belonging transmission coverage network. The command and the program are transmitted to the corresponding receiving terminal through the transmission overlay network, and the receiving terminal with the emergency broadcasting function is activated and receives the emergency broadcasting program in the standby state.
The emergency broadcast system adopts a digital signature mode to ensure the safety of the transmission of the emergency broadcast messages among the platform, the transmission coverage network and the receiving terminal.
In rural areas, emergency broadcast messages are mainly received through a loud speaker channel of a county-level emergency broadcast system. But the loud speaker system is a public resource and generally does not enter the home. Therefore, for rural residents, the emergency broadcast message broadcast by the large speaker system may not be heard or heard until the doors and windows are closed at night.
In cities, large-horn systems are difficult to see, and channels for receiving emergency broadcast messages are more, including medium-wave broadcast, frequency modulation broadcast, cable digital television, terrestrial digital television, new media systems and the like.
However, the modes are not registered for the home, because the product operators are too many, the intermediate links are complex, and the docking is difficult. The method adopted at present is to realize the butt joint of an emergency broadcasting system and a television station and then add an emergency broadcasting function plug-in on a television set-top box. However, because there are many set-top box manufacturers in the market, each city uses set-top boxes of different manufacturers, and the emergency broadcast function plug-in is difficult to implement by making an interface for the set-top box of each manufacturer. Therefore, the problem that the emergency broadcasting system is difficult to enter the house cannot be solved by adopting the method.

The most basic emergency broadcasting system includes an emergency broadcasting platform, a transmission overlay network, and a receiving terminal. The emergency broadcast platform receives the emergency information of the emergency information source of the current level and the emergency broadcast messages of the emergency broadcast platforms of the upper and lower levels, rapidly processes and produces corresponding emergency broadcast programs, generates the emergency broadcast messages by combining the emergency broadcast resource conditions of the current level, and broadcasts the emergency broadcast messages through a broadcast television frequency channel broadcasting system or a transmission overlay network.
The transmission coverage network comprises one or more of broadcast television transmission coverage systems such as a direct broadcast satellite, a mobile multimedia broadcast television, a medium wave broadcast, a cable digital television, a frequency modulation broadcast, a ground digital television, an emergency broadcast loud speaker system, a mobile emergency broadcast system, a new medium and the like. The functions of receiving, verifying, responding and automatically broadcasting the emergency broadcast message are realized by deploying necessary equipment such as an emergency broadcast adapter at the front end/station.
The receiving terminal responds to the emergency broadcast transmission coverage instruction and displays the emergency broadcast content in the following modes:
1) The prior radio, set-top box, television and other terminals. The radio, the set top box and the television which are listening to and watching the emergency broadcast frequency channel can listen to and watch the audio and video programs of the emergency broadcast in time.
2) Terminal with emergent broadcast awakening function. The emergency broadcasting system comprises a live broadcast satellite set top box with an emergency broadcasting function, a mobile multimedia broadcasting television terminal, a cable digital television set top box, a ground digital television set top box, a frequency modulation loudspeaker box/sound column, a TS loudspeaker box/sound column, an IP loudspeaker box/sound column and the like of an emergency broadcasting loud speaker system, and a special terminal which is in butt joint with public broadcasting systems of cities, public broadcasting campuses and the like, and the direct broadcast system locks and receives a command according to transmission coverage command transmission mechanisms of different channels and is started to respond in time.
3) A new media terminal. The system comprises a computer, a mobile phone, a tablet personal computer, mobile wearable equipment and the like, receives emergency broadcast messages pushed by a new media platform, and timely prompts a user to listen to and watch the emergency broadcast messages in a message prompting mode, a sound prompting mode and the like.
