      The 21st century, the era of human information technology into the high-tech, modern government conference design not only improve the structure of equipment, stable system operation quality, the most important thing is a set of high-performance intelligent intelligent multimedia information management system, so that the system The operator is easy to operate, the user is comfortable to use, for this, we "intelligent meeting, global sharing" based on the pursuit of technological innovation, comprehensive modern government building conference room, force a meeting system using the most high- The era of revolutionary high-tech in the future for a long period of time with the advanced nature and versatility.
      Large-scale conference system mainly consists of high-grade conference hall, large-scale multi-purpose hall, banquet hall and auditorium, and its function is mainly divided into large, medium and small. Is to hold large conferences, forums, academic exchanges and theatrical performances.
      Medium-sized conference system is mainly medium-sized conference rooms and multi-function hall, its main function mainly to the meeting.
      Small conference system is mainly ordinary conference room, its function mainly to small meetings.
System design technical indicators
      What do we do in the face of such a large number of conference rooms in a building:
      ① how to solve the scene of the acoustic feedback whistle phenomenon?
      ② how to do "language sound reinforcement level?"
      ③ how to achieve a centralized management of each conference room and control all the audio signal?
      ④ how to make the operator easy to operate, the user comfortable?
      ⑤ how to use and control means to adapt to the various functions of the meeting needs?
      ⑥ how to use the building's network resources to use in various venues to go?
      ⑦ how to achieve the meeting more comfortable, humane, technology and decent?
      (一), in the face of seven major issues we have put forward the "network, digital, intelligent, integrated," the "four modernizations" as the core system for solving the government building of the use of each conference room meeting needs : Speaking, voting, simultaneous interpretation, video tracking, recording and broadcasting, signal source management and control, peripheral equipment control and management.
      (二), since the "four modernizations" based on a wealth of network resources to rely on full-duplex lossless signal transmission at the same time by virtue of high-performance advanced DSP audio processing digital technology, integrated automatic feedback cancellation (AFC) / automatic echo Cancel function (AEC) / automatic gain control function (AGC) / automatic noise cancellation function (ANC).
      (三), the traditional audio processing equipment used in analog circuit design, the general delay, pressure limiter, equalizer, crossover, and so peripheral equipment between the use of a large number of wire connection not only lead to audio loss and sound Signal to noise ratio greatly discount, with the rapid development of information technology, people are using more and more electro-acoustic devices, each system must operate the operator's professional training before using the traditional system Equipment, so many and cumbersome system design simple system operation, the "one-stop" system management and control? So revolutionary DSP digital audio processors are springing out of the market, as long as the use of computer operators The system can be simple operation and control.
      (四), the venue of the acoustic feedback whistle is the most troubled audio debugger problems, the face of the problem of howling the traditional debugging method to sacrifice the pickup pickup distance to control the sound field whistle or frequency shift feedback suppressor, balanced AFC \ AEC \ AGC \ ANC "4A" processing function to achieve the AFC \ AEC \ AGC \ ANC processing functions, the use of the latest DSP digital processing technology, the A / D conversion of the signal processing without loss, to suppress whistle, the signal loss rate is extremely high , To the sound field, "the language of sound reinforcement of a standard." At present, there is a banquet hall, auditorium or multi-function hall in the conference room of the government building. The centralized management and control room of such a large venue is a difficult problem, especially the traditional audio processing equipment is difficult to meet the needs of a multi- The use of traditional peripheral audio equipment on the audio debugger will be a great test, and perhaps the convening of each function, such as: multi-function hall to hold large conferences, academic forums, or both training, small theatrical performances, Different times of the meeting of the audio transmission line to the non-stop plug replacement, so not only delay the meeting held at the same time greatly reduce the efficiency and reliability, as a result of this digital audio processor is due to this came into being.
So the operator only has a computer, control system or processor control panel, one of the tools can be real-time switch out of the current required various modes, no longer need to spend time plug-in mode of operation, only one Button to complete the data stored in the memory out to achieve instant multi-function mode that allows the operator to operate easily, the user comfortable to use to achieve a variety of functional needs of the meeting!
      (五) With the development of digitalization of network, a kind of audio system based on CobraNetTM protocol of Ethernet is born. It adopts low noise / wide dynamic input / output A / D conversion, with 24bit Of 64 times oversampling, D / A conversion to 24bit 128 times oversampling, using the delta-sigma modulation method. For example: the armed forces command center of the traditional approach is through the broadcasting system for voice signal transmission, this approach not only signal transmission noise ratio is poor, while poor voice quality, voice loss is extremely high, while wasting wire, wiring cumbersome, and now Practice using Ethernet channels for digital transmission of voice, so that not only loss of voice, and each point just cloth a Cat 5 (CAT5) transmission can achieve all the voice signal transmission, and between each other Voice full-duplex transmission, so a variety of venues of the local network resources to use without delay, lossless voice real-time transmission.
      (六), the purpose of integration is to achieve the network, digital, intelligent fundamental, embodies a comprehensive multi-media system, truly embody a technology based on IT, digital technology, network technology, microelectronics, computer Interactive, communication distribution, communication technology to achieve voice, image, text, graphics and other data information storage, processing, transmission, in people, people and machines, machine and machine contact between each other to achieve resource sharing .
      (七), YMIOO digital conference system using a unique trend of aesthetic design and practical technology innovation, breaking the state-owned many industry manufacturers over the years has been imitating the appearance of foreign brands and technology, reflects a by the Taiwan R & D The production of YMIOO brand in mainland China "wisdom" made of aesthetics and technology breakthroughs, especially the industry's first digital electronic table conference system, the system unit not only retains the traditional function of the conference unit (speech discussion, video tracking, Voting, sign-in, simultaneous interpretation, anti-RF radio frequency interference), the most feature is a 256x64 pixel high-definition electronic vacuum phosphor screen ---- VFD screen (Vacuum Fluorescent Display). Conventional meetings in the past usually only put a few conference pickup microphone and sound reinforcement equipment, all guests or leaders of the names are used to do the instructions card, this link not only did not improve the efficiency of staff, but also a waste of paper Resources, almost every meeting of different leaders had to re-print a card, completely to promote "low carbon" lifestyle contrary; in order to better save manpower, improve efficiency, the meeting more comfortable, human nature (YMIOO) from reality, the introduction of the new concept of the meeting, the successful launch of the industry's most representative and characteristics of the digital electronic table conference unit, the unit can not only show the names of participants, At the same time can show the title of staff, so that participants to the venue that is clear at a glance where their own seats, but also indirectly to the information passed to the participants know each of the leadership level, let us further Understanding and communication. At the same time with the YMIOO (excellent wheat) R & D and production of digital audio processor supporting the use of multi-site audio centralized management and control, so that logistics staff more effective management of the meeting process, making the meeting more smooth and smooth.
