System Introduction
KV-Distributed Intelligent Control Interactive Management System
The distributed intelligent control interaction management system is a visual information interaction management platform for audio and video applications. It collects, transmits, controls, and centrally controls sound and images, integrates multiple information streams such as audio, video, and computer data into one, and transmits them interactively over the network. It provides a complete solution for audio and video transmission and control for command and control centers, emergency dispatch centers, and large conference centers.

Research and Development Background

Fully distributed architecture with gigabit network for rapid interconnection
Each DMCS core node works independently Any node failure has no impact on other nodes Provide overall system reliability Flexibly utilize space and arrange it in a dispersed manner

Cross screen roaming, multi screen splicing, and any layout within a single screen
Each unit has bidirectional interaction capability for audio and video control Customizable resolution output suitable for large screens Multiple windows can freely roam and overlay within the large screen 16 layers of images can be displayed simultane

Bi directional feedback audio and video simultaneous interpreting, control integration
Timely bidirectional feedback The central control capability is so powerful that it is not only operable but also controllable It can also be obtained in a timely manner Sound, light, electricity, temperature, humidity, PM2.5, etc Real time feedback o

Difficulty in information transmission
Difficulty in remote access and sharing of information

Difficulty in summarizing information
Signal independent display, lacking true information aggregation

Difficulties in system management
Lack of unified control, system integration, and linkage

Encoding and decoding capability
This system adopts H.265 encoding and decoding technology, supports encoding 4K60 videos, decoding 4-channel 4K videos or 16 channel 1080P high-definition videos; Breaking through industry technology bottlenecks, users no longer have to make difficult trade-offs between image quality, bandwidth usage, and decoding capabilities, meeting their needs for high-resolution, high restoration, high synchronization, low bitrate, and low latency video usage

Lossless audio transmission
Our self-developed network audio and video transmission protocol ensures pure and lossless transmission of audio in the network, perfectly solving a series of problems such as interference, noise distortion, etc. in audio transmission over the network
system function
Decentralization
Distributed systems consist of input and output nodes, all of which use embedded hardware and are completely decentralized, making the system stable, secure, and reliable.
Composed of multiple independent autonomous nodes;
Adopting embedded Linux operating system;
The chip platform is of carrier grade, with stable operation and high reliability.

Visual operation experience
Drag, zoom, and move (full screen roaming)
Extremely user-friendly operating system, modern design interface
Preview, feedback perception, situation tracking
Features that enhance user experience
Intuitive operation and easy to learn
Humanized human-machine interface, design operation interface according to user customization needs
Large screen display monitoring
Application software interface preview visualization, system video preview visualization, large screen status display visualization, system status visualization

Interactive control and display functions
Image stitching
Support LCD, DLP, LED splicing
Image overlay
Supports stacking of 16 layers of 1080p images
Image Roaming
Support cross screen roaming display of any image
Image segmentation
Single screen supports 4-channel 4K or 16 channel 1080p split display

Visualized Operation
Quickly and accurately complete window layout
The software interface is designed for layout operations of large screen splicing, with a concise and clean operation process, resulting in immediate operational results
Pre layout display process
After the layout is completed, if you want to modify the large screen layout but do not want the large screen display layout process, you can achieve it through pre layout
Can be directly applied to large screens
The splicing screen can quickly switch to a new layout, or the pre layout can be saved as a scene and called when needed

Simple wiring and low cost
The input-output nodes can achieve interconnectivity of the entire system by connecting to the switch through only one Ethernet cable

Distributed KVM Agent Management System
One person, multiple machines, one machine, multiple screen signal switching: supports mouse scrolling roaming, one set of mouse and keyboard can operate multiple screens, manage multiple machines, support image segmentation, single screen can view and operate multiple servers simultaneously, increasing the range of information viewing. Seat personnel can push information from local displays to any display or large screen, and can also capture information from any display or large screen to local displays
