Description

Technical Field

[0001] The utility model relates to the technical field of emergency broadcasting, and in particular to an integrated emergency broadcasting active publishing terminal based on SOC. Background Art

[0002] Digital broadcasting involves encoding, modulating, and transmitting digitized audio, video, and various data signals in a digital state. Digital broadcasting differs from traditional AM and FM broadcasting technologies in that it transmits digital signals through ground-based transmitters.

[0003] IP broadcasting is a purely digital audio broadcasting system based on a TCP / IP network. Its physical structure is fully integrated with standard IP networks. This system not only enables broadcast, live streaming, and on-demand digital audio over TCP / IP networks, but also leverages the advantages of TCP / IP networks to overcome the content, spatial, and functional limitations of traditional analog broadcasting systems. Not only can it completely replace the functions of traditional analog audio broadcasting systems, but it also offers autonomous and interactive capabilities not found in traditional analog broadcasting, opening up new avenues for remote broadcasting applications.

[0004] Direct Broadcasting Satellite (DBS), commonly known as high-orbit satellite communications, utilizes communications satellites in geosynchronous orbit to transmit high-speed broadcast data to user antennas. This technology, commonly known as high-orbit satellite communications, transmits large amounts of data via satellite transponders using frequency-division or time-division modulation methods, and plays a crucial role in my country's radio and television transmission coverage network.

[0005] At present, emergency broadcast receiving terminals have a single signal receiving mode, which is pure digital, IP or live satellite broadcasting. Emergency channel backup is impossible during use. Once the channel is damaged, information cannot be transmitted, causing trouble, especially in emergency situations, and even resulting in huge losses of people’s lives and property.
