Promote visual dispatch and command with distributed image center

With the acceleration of my country's informatization construction process, various industries are paying increasing attention to visual dispatch command and control. More and more users expect to integrate operation management, production dispatch, security monitoring, emergency command and other systems to achieve the goal. Remote presentation of large screen signals and interaction between various screens, thereby building a cloud management platform for information sharing.
At present, the information data of command and dispatch centers in various industries is ultimately displayed in the form of image information. Therefore, from a usage perspective, the command center can be regarded as an image processing center, which is responsible for the collection, transmission, processing, interaction and presentation of various multimedia signals. Only the processed image information has practical application value.
In order to meet this market demand, Vision Technology has launched the AS-ADS high-definition distributed display control agent solution after years of in-depth exploration of image center application scenarios and research on user usage habits. This solution adopts a decentralized distributed architecture to create a visual collaboration platform. It is a management collaboration system with leading technology, complete functions, stable performance, safe and reliable, convenient operation and convenient expansion. It is also the most extensive command and control system solution in image center scene applications.

AS-ADS 高清分布式显控坐席解决方案基于 IP 化、无中心化的设计理念，运用嵌入式架构，为用户提供音频处理、视频拼接处理、视频会议处理、网络传输、环境监控、KVM 坐席协作、可视化控制等多种功能集于一身的现代化、网络化、互联互通的智能化管理平台。
Distributed systems have advantages such as TCP/IP network protocol signal transmission, versatility and flexibility, which expand more possibilities for system construction. Based on the IP architecture, all computers and audio and video equipment can be distributed and organically integrated through the IP network. The system can achieve decentralized deployment, and can also interconnect audio and video signals from the image center lobby and supporting duty rooms, conference rooms, and decision rooms, thereby realizing flexible networking.
The system collects audio, video, USB keyboard and mouse signals through distributed input node equipment and encodes them into the network switching system to achieve flexible call. Then they are decoded and restored into interactive digital signals through distributed output nodes, further achieving large-screen display, agent collaboration and other application-layer functions. The audio and video collection, transmission, control and display aspects of the image center can be easily connected through a digital network for centralized management and control. It has great flexibility and expansibility, and supports multi-point sharing of audio and video signals, Mobile device preview control, audio and video communication and other functions.
