Emergency broadcast audio and video files of the emergency broadcast type and emergency broadcast level, and loop during the boot stage of playing the boot audio and video files to realize the emergency broadcast function.

As a further improvement of the present invention, in the process of cyclically playing the start-up audio and video files on the TV, the text information of the emergency broadcast is continuously obtained through the OSD function of the HDMI CEC bus, and superimposed and displayed on the start-up screen, prompting the user to escape or avoid danger .

In the present invention, the local storage of the television set contains emergency broadcast audio and video files of different types and levels. When the TV receives a specific emergency broadcast instruction through the HDMI CEC bus, it judges whether the instruction is an emergency broadcast instruction by parsing the instruction. If it is an emergency broadcast instruction, continue to parse the instruction to obtain the emergency broadcast type and emergency level. After parsing the emergency broadcast command, the TV calls the corresponding emergency broadcast audio and video files to replace the original boot video and audio files of the TV. After the replacement is completed, the TV adjusts the volume to an appropriate size, and starts the TV, and repeats the loop in the stage of playing the startup audio and video files until the TV power is turned off.

The specific emergency broadcast instructions based on the HDMI CEC bus are based on the HDMI CEC bus. The instructions are generated by the set-top box according to the agreed method. The TV can obtain information such as the emergency broadcast type and emergency degree by parsing the instructions; the set-top box is obtained through wired, wireless or satellite communication. After the emergency broadcast command needs to be issued, a specific emergency broadcast command is generated and sent to the TV through HDMI CEC; the emergency broadcast audio and video files stored in the TV are stored in a fixed location by default when leaving the factory, and can be updated through the network; the set-top box can be updated through HDMI The OSD function of the CEC bus transmits text content to the TV, and displays it on the TV screen when the TV is turned on.

The beneficial effects of the present invention are:

The present invention is aimed at supplementing the existing emergency broadcasting system. The emergency broadcasting system of the existing set-top box can only broadcast in other ways or rely on the speaker that comes with the set-top box when the TV is on standby. Due to the volume and cost constraints of the set-top box, the volume level that can be broadcast by its built-in speaker is relatively low. If the user is asleep or in other ways, it may not be able to effectively receive the emergency broadcast information. Through the technical solution of the present application, the set-top box can be used to wake up the TV for emergency broadcasting. Compared with the set-top box, the speaker power of the TV is obviously greater than that of the set-top box, which can prompt the user to avoid danger in a timely and effective manner.
