Multimedia Integrated Control System
The multimedia integrated control system adopts the UT series audio and video integrated machine as the core control equipment. The multimedia control host adopts the design concept of ALL-IN-ONE, with a software visual operation interface platform and hardware plug-in modular design, aiming to provide users with an industry integrated solution.

system function
Support 4K high-definition mixed matrix
Support local SDI VGA、HDMI、DVI、CVBS、 Fiber optic, HDBaseT input image, network IPC network stream input, local image output using RGB4:4:4 technology, high-quality image quality, no delay or damage. The network video stream adopts advanced H.265 and H.264 High Profile encoding and decoding technologies to meet the requirements of high image quality and low latency applications under low bandwidth, while solving comprehensive applications such as image quality, storage, interaction, and visualization. Supports protocols such as TCP/UDP/RTSP/RTP/ONVIF/H.263/SIP/HTTP to achieve integrated communication of streaming media signals and local signals, and enables centralized management, visualization, and arbitrary calling.
Digital Audio Processor
Using a 16X16 audio processor core, it can perform mixing, gain, noise reduction, echo suppression, and other processing on the connected audio. It supports fast switching and pre plan switching of audio signals, audio encoding, and centralized audio processing in venues such as conferences and command vehicles.
Programmable central control system
For the convenience of users and to improve work efficiency, a central control system with powerful control functions is designed for each conference room. The operation and control of numerous devices are completed through the central control system, and the pre debugged states of some complex devices are stored. Users only need to operate the touch screen with an intuitive all Chinese interface to complete the operation of most functions of the entire system.
System control can achieve the following functions: users only need to sit in front of the touch screen to intuitively operate the entire conference system, including system switches, device switches, various audio and video signal switching, signal source playback and stop, various combination mode entry and switching, as well as the conference audio system used for sound reinforcement; A digital conference system used for discussion, voting, and voting; Video conferencing system for remote meetings; Large screens and projection systems used for video display; Multimedia peripheral devices used to provide audio and video signals, etc.
Support visual control interface
In traditional conference rooms, equipment is centrally controlled and managed by a central control system. Software programming is performed on the operating end, and various operations are achieved through control buttons. This solution often encounters the following problems when controlling video signal switching:
It is impossible to determine in advance whether there is a signal in this video.
It is impossible to determine in advance whether the video signal effect is good or not, whether there is a lack of color or patterns.
It is impossible to determine in advance whether the camera image is correct or not. Do you need to adjust it in advance.
So often, images with no signal or poor effects are switched to the big screen, which affects the usability.
In order to solve the above problems, the HAIMINGWEI system has added a visual control platform IMC. On the IMC platform, the video image of any distributed node can be viewed, and the operator only needs to drag the corresponding video to switch the video signal. The visual management platform IMC also supports centralized control management, scene management, audio management, interactive terminal communication management, recording management, central control management, equipment information management, etc.
Support built-in 4K ultra clear recording and playback, video terminal, 4-point MCU
HMW supports built-in 4K ultra clear recording and playback, video terminal, 4-point MCU function, adopts H.265 encoding and decoding algorithm, and supports H.263 \ SIP protocol. All mainstream video conferencing systems in the industry are interoperable. The visual management interface enables the switching, starting, and stopping of recording signals, as well as the calling and hanging up of video conferences.
