What is a distributed audio and video system?
In this modern information-based, networked, and big data era, people have increasingly higher requirements for audio and video control systems. The advantages of distributed audio and video systems are their unlimited bandwidth, decentralized architecture, networking, modularization, high stability, and high scalability, which make them more adaptable to the constant changes and developments of this era. Therefore, they can be applied in multiple fields with greater advantages.
Distributed audio and video systems are relatively simple to wire. Traditional audio and video systems, however, have numerous devices with varying brands and models, and their interfaces vary widely. Initial system design requires detailed consideration of each device's data interface, and during the wiring phase, multiple cables are required for each device, which not only wastes time but also significantly increases costs. Distributed systems, however, utilize a fully networked design, requiring each device to connect to a switch using a network cable. This simplifies both design and wiring, significantly reducing costs.
Distributed audio and video systems are easy to expand. Each multimedia device is independent yet tightly connected. Each device exists independently within the system and does not affect other devices. They are indirectly connected via switches, and data exchange is carried out using distributed computing units (DCUs) that assign IP addresses to them. In conference room applications, network ports are reserved in table or floor sockets during conference room design. Therefore, when adding input or output interfaces, simply connect the device to the distributed system switch via the network, making expansion easy.
The distributed audio and video system has a two-way control link. Therefore, without the need for additional equipment, the system operation center unit can obtain various terminal statuses, such as the projector's lamp duration, third-party operation information of external devices, etc., and feedback in any format to the screen, software, and WeChat or email with authorization, which greatly facilitates system maintenance.
The distributed audio and video system enables PC soft access. After authorizing and installing the software on a computer, the computer's signals can be used as input into the switching network for distribution or access by other devices. The playback software on the computer can also be controlled from the human-machine interface. After authorizing and installing the software on a computer, Android device, or iOS device, all input signals connected to the switching network can be viewed from the computer or other platform software. This makes high-definition segmentation easy, greatly improving human-machine friendliness and significantly enhancing the coordination of large-scale conference schedulers.
The remote control function of the distributed audio and video system can be used with APP and other software to achieve remote control or remote acquisition of local images under authorized use. This is extremely beneficial for high-end families, villas, and clubs. No matter where you are, everything is under control.
Where can distributed audio and video be used? YZ Audio Visual will provide you with a detailed introduction:
1. Distributed audio and video systems are large in scale.
Distributed audio and video systems support a large number of input and output signals and require massive signal management, which requires processors with sufficient bandwidth. Traditional processors have limited bandwidth, making this difficult or even impossible. Network distributed controllers, with their unlimited bandwidth, are now in full force.
2. Distributed audio and video system expansion.
Distributed audio and video systems are likely to need upgrades, expansions, or integration with other systems in the future. Network distributed controllers can easily achieve this without replacing hardware, significantly reducing costs and eliminating waste. Traditional processors, on the other hand, require almost complete hardware replacement, which is extremely costly.
3. Multi-screen management of distributed audio and video systems.
A distributed audio and video system requires managing multiple large screens, whether within a building or across multiple locations. Signal sharing and multi-screen linkage control are essential. A network-based distributed controller easily handles this.
4. Cloud-based touch control of distributed audio and video systems.
Using standard TCP/IP network format, data can be flexibly connected to computers, iPads, mobile phones, and other smart terminals, enabling easy and convenient preview and control of large screens anytime, anywhere.
5. Distributed audio and video systems offer simplified cabling.
Distributed audio and video systems utilize Category 6 network cables for long-distance, lossless signal acquisition and transmission. End-to-end signal transmission can reach over 100 meters, while fiber optic transmission can reach even further. Network cabling simplifies installation and reduces costs.
Distributed audio and video systems offer distinct features and are a new generation of central control systems. They are particularly well-suited for use in many fields, such as public security, government, military, enterprise, and factory environments. These requirements are often met. Choosing a distributed processor can better adapt to future development trends, and distributed applications are expected to become increasingly widespread.
6. Distributed audio and video systems offer low maintenance costs.
Each node in a distributed audio and video system operates independently, so a node failure will not affect the entire system. Nodes boot up quickly and are easily replaced with plug-and-play functionality, ensuring maximum system security and low maintenance costs. In contrast, a failure in a traditional centralized processor might require replacing the entire system, potentially disrupting operation and requiring a complete replacement of the entire backplane. This results in high maintenance costs.
