Xibang IP network broadcasting system adopts the TCP/IP network technology widely used in the world today, and transmits audio signals in the form of standard IP packets on LAN and WAN. It is a purely digital transmission two-way audio reinforcement system. It completely solved the problems of poor sound quality, complex maintenance and management, and lack of interactivity in traditional broadcasting systems. The system is simple to use, easy to install and expand. It only needs to connect the audio terminal to the computer network to form a powerful digital broadcasting system. Each access point does not require separate wiring, and it truly implements computer networks, digital video surveillance, and public broadcasting. Multi-network integration.
The IP network broadcasting system is completely different from the traditional broadcasting system, the FM addressable broadcasting system, and the numerical control broadcasting system. Due to its digital network technology, which is built on a common network platform and integrated into Sibon's own intellectual property, it manifests significant advantages in many ways:
Functionality: Each terminal can be independently controlled to play different content (eg, 200 terminals in a local area network can broadcast 200 programs at the same time). Not only can we fully implement the functions of traditional broadcasting systems (such as: regular ringing, partition playing, fire alarms, etc.), but also have functions such as terminal free on-demand broadcasting and two-way intercom between terminals;
In terms of transmission, the audio transmission distance is infinitely extended, and it can run on cross-gateway local area networks and Internet networks. It supports a wide range of important applications, from centralized control of broadcasts from the main campus to the sub-campus, and from the corporate headquarters to simultaneous broadcasting of regional divisions. To achieve fast and reliable information communication;
In terms of sound quality: The output sound quality of the terminal is close to the CD level (44.1K, 16bit), which satisfies the occasions with high requirements for sound quality, such as the college entrance examination, college level 46 examination listening, and daily foreign language listening training in the classroom. Each pronunciation is It can be clearly discernible and no longer plagued by ambiguous sounds;
Reliability: The server (Windows operating system) and the IP network master (embedded operating system) provide dual insurance. If one side fails, the other can take over all terminals to ensure that the basic functions of the system operate normally. Both the host computer and the terminal use industrial-grade chips. They work 24 hours a day and are completely immune to viruses. With mature Ethernet hardware, the entire system does not require additional line maintenance.
Advantages of the IP network broadcasting system l More powerful functions The pure digital broadcasting system covers all the functions of the traditional campus broadcasting system. And to achieve audio on demand (AOD). And make full use of the resources of the campus network, can access the audio resources on the network anytime, anywhere. Since each terminal has an independent IP address, it is possible to control any one terminal to play different programs. Better sound quality Because of the use of network transmission technology, audio signals are free from interference and distortion. Using MP3 compression algorithm occupies a low network bandwidth (8k-128k) and can guarantee the fidelity of the sound quality. It has been tested to use a 44.1khz16bit sampling 128kbps rate compression passband (line output) 20-16khz, distortion ≤ 3%
l Higher reliability The unstable factors of the campus broadcasting system mainly depend on the quality of transmission lines, unreasonable transmission lines or causing instability or even burning high-power constant-voltage power amplifiers. Pure digital broadcasting system Thanks to the mature Ethernet communication technology, each terminal equipment is equivalent to a simple computer connected to the campus network. Users only need to ensure the smooth flow of the network without adding any additional maintenance.
l Simpler installation and easy installation. As long as you have the following three conditions: There is an AC 220V outlet, a standard Ethernet access jack (RJ45) and a place to put down the digital broadcasting terminal (the volume of a speaker).
Problems with traditional broadcasting systems l The technology is backward, and the compatibility and scalability are not good. The existing broadcasts are basically analog transmission and manual management. The system is susceptible to environmental interference, and crosstalk easily occurs during multi-channel broadcasting. The digital format audio file cannot be directly played on the terminal and cannot be connected to the network. The audio source digitization and playback management are truly automated.
l Single function The current broadcasting equipment can only be used for programs within 6 channels, which cannot meet the requirements of modern projects for high-quality sound and up to several tens of road programs.
l Installation is complicated and inconvenient to maintain Because constant-voltage cable broadcasting is configured in strict accordance with the principle of impedance and power matching, a power amplifier is often burned due to a transformer or speaker failure, which affects the entire broadcast.
L lack of manageability, remote control can not be used as a special playback device (tapes, discs, CD players, etc.) and computers that store MP3 files as the source of sound, the need to specialize in the management of broadcast content in a dedicated location, so can not use modern technology The effective management of broadcast sources makes it impossible to perform remote play control, which is not conducive to the flexible application of broadcast systems, resulting in waste of resources.
The rapid development of network technology has led to an increase in the use of IP network broadcasting. IP network broadcasting, as the fifth generation of public broadcasting products, has a qualitative leap in its role and characteristics compared to previous public broadcasting. IP network broadcasting is essentially a local area network. Or the Internet is a transmission medium, and products that are connected to public broadcasting systems and have public broadcasting capabilities are implemented.
IP network broadcasting, as the successor of the first four generations of broadcasting, has all the functions of the first four generations of public broadcasting. At the same time, IP network broadcasting also has the following characteristics:
1, breaking the transmission distance limit. IP network broadcasting turns the signals transmitted by traditional broadcasts into digital signals so that they can be transmitted to any desired place through the Internet or a local area network, breaking the distance limit.
2, with interactive features. Traditional public broadcasting is a one-way Communication System. It does not have the function of interacting with terminals. IP network broadcasting is different. It not only has multiple interactive functions but also can achieve resource sharing.
3, reduce costs and installation difficulties. IP network broadcasting can be established based on the existing Internet network. It does not need to be re-routed, and it is easy to realize multi-network integration. Even if wiring is needed, only one ordinary Category 5 cable is required, which greatly reduces costs and installation difficulty.
4, broadcast sound quality enhancement. Compared with the analog signal transmission of other public broadcasting, the digital transmission of the IP network broadcast has the characteristics of small distortion and high signal to noise ratio, and the sound quality is close to the CD level.
This is the characteristic of IP network broadcasting compared with traditional public broadcasting. With the development of network technology, IP network broadcasting will surely become the mainstream public broadcasting system in the future. Public broadcasting professional manufacturer!

Tax-included Total Price Product Free Warranty One-year IP Digital Broadcasting vs. Traditional Broadcasting Advantages Serial Number Broadcasting Basic Functions Digital Broadcasting Analog Broadcasting Comparison 1 Background Music Playback Digital IP Network Broadcasting System Using Network to Transmit Digital Audio Signals, Audio Signal Quality Reached CD level. Traditional broadcast transmission of audio signals over long distances makes it difficult to guarantee audio signals, often introducing noise and current sound. The sound quality is not at a uniform level, and digital broadcasting is obviously superior to traditional analog broadcasting.
2 Temporary Broadcast Background Music Using the digital IP network broadcasting system, it can be easily solved, and the operation is simple, and the program is arbitrarily selected for playing. No need to go to the radio room operation. It is very difficult to implement this function using a conventional broadcast system. Even if it can be realized, the operation is also very tedious. Must go to the radio room operation. Digital broadcasting can directly connect the audio source or microphone to the floor terminal to achieve the broadcast. Analog broadcast can only be operated in the computer room.
3 Business language broadcasting The paging of microphones over IP networks can convey important broadcast information without distance restrictions, delays, and high fidelity. Generally, the operation can only be completed in the engine room. Even if it is a remote pager, the distance is strictly limited, and it is difficult to ensure that there is no delay problem. At the same time, noise and interference problems cannot be solved. IP network paging microphones can be used for remote pager broadcasting and intercom in places where access to the network is available. This is not possible with analog broadcasting.
4 Emergency Broadcasting A more efficient and stable digital fire-fighting linkage system is unique to digital broadcasting. The fire-fighting system comes in a temporary system to broadcast fire-fighting voices in a customized manner and secure personal and property security in office buildings. The alarm voice format has limitations and the stability needs to be improved. It may not be able to quickly, accurately, and clearly communicate alarm voice information. The alarm mode is relatively simple and not humanized. Digital broadcasting has a relatively independent emergency broadcast processing system. It can configure alarm linkage modes without restrictions according to actual needs and accurately communicate fire information at the first time.
5 Scheduled broadcasts You can enter the play schedule programmatically by day of the week or date and the system will automatically run. The program is set up once, and no manual switching is required during the season. Large screen Chinese color display window, at a glance. All working status of the system is displayed intuitively. The process of programming or writing programs by the host computer is not humanized enough to achieve regular broadcast once and for all. Digital broadcasting operations are more humane, more convenient and more adaptable to the trend of the times.
6 Broadcast Management Software Server login uses password login management, and distinguishes administrator and operator login passwords. The administrator has the highest system setting authority to ensure that the server system security broadcast system can be managed hierarchically in analog systems. The digital broadcasting system login can set different levels of management authority to ensure the security of the broadcasting system.
7 sub-control system supports multiple remote software operating systems, through software settings, each floor or floor can only be responsible for each network audio terminal in the area, can not control other areas, modify and reset is very convenient. Only broadcast in the master control room. The broadcast system partition management function is not in place. Analog broadcasts are difficult to achieve a true partition control system.
8 System Standby System When no broadcast is performed, the terminal server is turned off, and the speaker can't hear any noise. This not only ensures the cleanliness of your work environment, but also greatly improves the service life of the equipment and speakers. When a broadcast signal enters the terminal server, it automatically releases sleep and broadcasts. Traditional broadcasts are in standby mode and noise can't be avoided. Digital broadcasting is an upgraded version of analog broadcasting. The digital broadcasting system is more in line with the real world of energy conservation and environmental protection.
9 Convenient operation The IP network broadcasting system combined with mouse and keyboard operation not only displays intuitive, it is more user-friendly, and it has a large touch screen. It can display the current working status of the system in real time and has good man-machine conversation function. The beginners can easily master without professional training. , easy to learn and easy to understand and easy to operate. The tedious key operation of analog broadcasting, its characteristic decides that the user needs professional training to use the function of the broadcasting system correctly. The digital broadcasting system software platform is a computer operating system, which is in line with people's operating habits, and has a high degree of user adaptability. This is something analog broadcasting can't match.
10 System maintenance The IP network broadcast is shared with the network physically, so it does not add extra maintenance work beyond the network maintenance. In the application, the system can separate the separate network segment from the computer, and the embedded broadcast system program of each network broadcast adapter is solidified. Will not be infected by the virus, the system as a whole is highly stable and reliable. Not compatible with the network. System stability is inferior to digital broadcasting. The tedious cabling method determines the inconvenience of system maintenance and troubleshooting. The digital system can be built on the existing network system, but it does not affect the original system functions and does not require rewiring. Pure digital transmission greatly reduces construction work and maintenance work.
The IP network broadcasting system is completely different from the traditional broadcasting system, the FM addressable broadcasting system, and the numerical control broadcasting system. Due to its digital network technology, which is built on a common network platform and integrated into Sibon's own intellectual property, it manifests significant advantages in many ways:
