Solution of Digital Exhibition Hall

Intelligent exhibition halls and intelligent service centers use many cutting-edge science and technology, Such as distributed 4K processing technology, Visual control cloud platform, Digital audio processing technology, etc., Access to new modes such as intelligent big data, efficient and orderly management, intelligent and powerful prevention and early warning, Realize the visual inspection and echo of urban community situation dynamics on the large screen of service center, intelligent early warning of security incidents, Urban service is efficient and convenient, which truly makes urban community management information visible, track traceable, status traceable, virtual and real synchronization, scene exchange, makes the past traceable and the future predictable, makes virtual service reality and data support decision-making, and creates a safe, convenient, livable and happy living environment for urban community residents.

Intelligent exhibition hall
In a highly reliable fully distributed architecture system, image processing is distributed in various signal processors. Failure of a certain processor only affects the signal or a certain unit display, but does not affect the normal operation of other processors and systems. Display high-precision synchronization to ensure that the upper screen display of large-screen monitoring signals and calculation signals in the service center has no picture tearing, no jamming, clear and smooth. Super signal processing capability, all RGB signals and video signals can be displayed in full screen at any window, any size, any position, any superposition, movement and roaming. The system supports signal multicast, the same monitoring signal source can be displayed on any number of display units at the same time, and all windows are synchronized in real time.

Intelligent service center platform
The monitoring signal is directly accessed and displayed, and the IPC decoding capability is integrated, which can realize the direct access and display of IP streaming media video in H.264, MJPEG and other coding formats. The high-definition IP monitoring signal can be directly transmitted to the large screen display of the city service center through the network. It can realize the management of massive network cameras, support IP cameras such as CIF, D1, 720P and 1080P from mainstream manufacturers at present, and support multi-channel IP camera streaming media signals from different manufacturers to be displayed in real time in multi-screen windows with single screen, 4/9/16 pictures, any size, any position and any superposition mode. All signals are displayed in real time. Each signal in the system is processed by each signal processor in an independent channel, and only the information change pixels are refreshed to ensure the real-time processing and display of all signals. Display wall mutual mirror function, The system can realize the mutual mirror function between the display wall and the display wall pictures, It can solve the problem of full-screen synchronous mirror image display between the display wall of the platform center and the display wall of the conference room, which is beneficial to leaders' decision-making and command, watching performances in the same mode, and helping platform center personnel to accept instructions and make accurate judgments. At the same time, the control system and display system are backed up with each other in a real sense. Visual centralized control function. The system supports IFi (IPad WiFi Control) control function. Under the authorization of the administrator, the whole system can be directly controlled through IPad, and the control functions such as signal window opening, window closing, window scaling, dragging and plan calling can be carried out on the large screen in a visual way. Low power consumption, green and environmental protection, using standard CAT network cable for connection, compared with traditional analog cable and optical fiber DVI cable, the wiring cost is greatly reduced. At the same time, all signal processors adopt embedded design, each with a power consumption of about 15W, which reduces the overall power consumption of the system, saves the operating cost of the system, and saves energy and environmental protection.

Digital audio processing technology provides semi-open architecture ETHERNET, open user interface, integrated management of multiple devices, and excellent sound quality of 24bit/48kHz. Each channel is independent of adaptive feedback suppression, which automatically finds feedback points and automatically suppresses them. Adaptive echo cancellation (AEC), noise suppression (ANS). Gain Shared Auto Mix (AMC), Threshold Auto Mix (Gate Mixer), Auto Gain (AGC). Full-function matrix mixing (delay matrix), and the input mixing level can be adjusted. 16 sets of presets, each working independently. Eight GPIOs can configure input and output independently, and can be used as independent ADC when configuring input. Support channel copy, LINK and grouping functions, support RS232 central control and UDP central control, UDP port can be set freely, control software can view control code. Built-in USB sound card, supports recording and broadcasting and teleconferencing, and supports IOS and Windows systems.
