CMX SIP Airport Emergency Broadcast System

The Development Background of SIP Broadcast

With the development of science and technology, the limitations of traditional broadcasting have become increasingly obvious. Traditional public broadcasting ( PA ) relies on analog signal transmission, and has problems such as complex wiring, limited coverage, single function (only supports one-way broadcasting), the broadcasting system is not connected to the telephone, security and other systems, and it is difficult to coordinate responses in emergencies. The maturity of network infrastructure provides a high-bandwidth, low-latency network environment for IP -based audio transmission. As an open protocol defined by IETF ( RFC 3261 ), SIP has become a universal standard for multimedia session control, supporting cross-device and cross-platform communication. SIP broadcasting also breaks the limitations of traditional broadcasting and redefines network broadcasting.

Advantages of SIP Broadcasting1. Low deployment cost: Can be implemented within existing network infrastructure, reducing costs

2. Strong functional expansion: Supports evolution from one-way broadcasting to intelligent interaction and seamless integration with existing communication systems ( IP telephone, video conferencing);

3. Strong equipment compatibility: public protocol, compatible with broadcasting equipment from other manufacturers;

4. High flexibility and scene adaptation: flexible partition broadcasting, multiple broadcast modes and triggered playback to cope with various scenes;

5. High sound quality and low latency: high-fidelity audio transmission, up to 20Hz~20kHz full frequency band coverage; voice delay ≤100ms ;

6. High reliability and security: automatic switching between primary and standby IP networks ensures uninterrupted broadcasting; data encryption communication prevents eavesdropping or tampering; hierarchical authority management restricts unauthorized access;

CMX SIP Airport Emergency Broadcast System 

1. Cross-regional transmission: SIP broadcast system supports LAN, WAN and Internet transmission, and can cover different areas inside and outside the airport; 

2. Multi-terminal adaptation: Each terminal has an independent IP address and can play different content in different areas (such as boarding reminders for different flights), meeting the personalized needs of complex airport scenarios;

3. Multimedia support: SIP protocol not only transmits voice, but also integrates video, text and images (such as flight information screen, emergency evacuation route map), enhancing the intuitiveness of information transmission

4. Redundancy and stability: The SIP protocol reduces the risk of single point failure through distributed node design;

5. Save infrastructure costs: The SIP system integrates voice, data and video transmission through IP networks, eliminating the need for traditional telephone lines or dedicated hardware (such as TDM gateways), reducing deployment costs;

6. Emergency broadcast priority: The SIP system can set up emergency broadcast channels, automatically interrupt regular broadcasts in emergencies, and give priority to delivering key instructions;

7. Secure transmission mechanism: through encryption protocols (such as SRTP ) and network isolation technology, voice data can be prevented from being eavesdropped or tampered with, meeting the airport's high requirements for communication security
