【 Weak current College 】 multimedia conference room trends and design questions

Multimedia Conference Room 1
The Conference room is a very traditional vocabulary, but its unchanging meaning is "resolve interpersonal information exchange", the traditional conference room is very simple, the information exchange mainly on-site communication between participants, dependency and language and the body.
Audio technology that solves a large meeting space, the sound of delivery problems. With the advent of digital conference system solves the problem of management, etc.
Display technology, in particular the large screen display technology, let the room really resolve the "information exchange" Forum, a conference room as a "full of modern electronic equipment" Exchange platform, whether on-site or off-site Exchange Exchange possible, this is the modern sense of the multimedia conference room.
Multimedia conference room of the building is in the settlement of the meeting room space environment, resolve information acquisition, information transmission, information sharing, information exchange, information integration, information storage and communication.
In human understanding of the world, the eyes that the information received, the dominant position of the video display system in occupies room construction, followed by audio conference system and sound reinforcement systems, is a conference room environment again.

2 conference rooms, partition and type of
The kernel from the exchange of information, can be broadly divided into the type of room:
(1) one-way exchanges-meeting room, also known as broadcast communication, such as a lecture hall, Auditorium, training rooms, etc.
(2) two-way communication-room discussions, various types of rooms, including video-conference room.
One-way and two-way, nor absolute, just what is the primary problem.
From the perspective of space, can be divided into small, medium, and large and very large.
From the use of angle can be described as discussed in the meeting room, training room, Lecture Hall, the type of video conference room, decision-making centres, command and control room, show-rooms.

The development trend of 3 conference rooms
(1) numerous trends
The information society on a tremendous demand for communication, as human formal communication of the main places-Conference room number development also logical. Present in various Conference Centre, the Government administrative centre, Enterprise Management Center is a large meeting room needs, from dozens to hundreds.
(2) functional segmentation trends
Amount of increase, causing the room location of subdivision, segmentation functionality is also a trend.
(3) on-demand design trends
Subdivision of development, will inevitably lead to an on-demand design, in considering the flexibility at the same time, greater emphasis on accurate needs to configure the device, the device's stuffing, opposition against the same.
(4) the trend
Conference audio-visual environment with more emphasis on user experience, such as easy-to-use, visual comfort, hearing clear, beautiful environment.
(5) price trends
In addition to the one-time investment, require low operational and management of maintenance costs. The development of a multimedia conference rooms of large numbers of different types of professional technical equipment, usage, maintenance for users speaking is a cost, so in the design and technical means to ensure the operation and maintenance simple and efficient is also a trend.

Conference Room 4 lot (Group)-building issues to consider in
4.1 Division and conference rooms, meeting rooms, the relationship between the
When the Conference room number, no matter what kind of Conference Center, in fact, there is a conference room for attribution and management issues, the Conference Center in large enterprises, more time is a consortium of several corporate companies sharing a building, at this time, the room from the assets of generic relations is different, and in Business Conference Centre, Government Conference Centre and business centre and a common existence to manage different areas, so in the meeting room in construction, it is first necessary to determine the relationship under attribution and Management Division, according to function and Management Division.
To determine on the basis of the dividing (we call it the "domain"), and then determine the relationship between the Conference rooms, divided into separate, subordinate, equal in three types, including:
(1) different "domain" relationship between meeting room
* Relationship between AV signal;
* The relationship between the network;
* Control;
* The relationship between asset management;
* Daily management.
(2) the same "field" of the relation between meeting room
* Completely independent of each other;
* Some of the master-slave meeting room;
* Complete equality (networks, AV interconnection).

4.2 conference rooms location and needs analysis
In the initial classification, to individually on each of the "domain" in the Conference room to navigate and needs analysis. Including:
(1) orientation
* Room type positioning (Auditorium, multi-function Hall, TV room, conference room, training room, consultation, negotiation rooms, reception room, command and control center, analysis of decision-making centres, Exhibition Center, etc.);
* Meeting room grade positioning (consumer identity and used);
* Meeting room functions (specific functionality and control);
* Meeting room style positioning (Deluxe, ordinary, simple);
* Meeting room management position.
(2) demand analysis
According to the initial classification and positioning, design or integration company for making preliminary design of the system and with users of adequate communication, modification and adjustment, up to the technological and economic objectives. It is worth noting that the design and system integration companies need to be very familiar with modern Conference combined with modern room construction of content as well as international AV product of the latest technology and product supply in order to achieve a constant interaction between the technical and economic indicators, eventually formingThe entire room group construction of detailed requirements.

Conference Room "swarm" 4.3 construction technology development trends
(1) equipment operation and control
Because of the many meeting rooms, equipment and controls, into a prominent issue. Current technological trends is fully networked equipment control system, to achieve the meeting room equipment direct manipulation and control, "domain" centralized operations and control as well as the overall control of the whole system. Following the distribution control and centralized control, in accordance with the principle of convenient and reliable to use, look for a balance between the consolidated management.
(2) device management
Device management is divided into asset management and technology management (such as equipment condition monitoring). Current technology trends are all or most of the equipment in the Internet, through the network to detect the device status, do have a plan of repair and maintenance, and asset management.
(3) meeting room process management
The current device? the centralized control system can be Conference mode preset and process management, technology development trend is the theatrical performances based on the time of the introduction of process management function session management, network control equipment in accordance with a predetermined time to operate the device with the "preset" process, the stage performance of the program.
(4) the application of the concept of operational costs
For full terms of semiconductor devices, the equipment life cycle are far greater than the update cycle, but in the Conference room to the extensive use of display devices, whether projection or PDP, LCD technology, there is a consumable replaced, life cycle, run maintenance, one-time investment and for the entire life cycle of operating expenses to overall consideration is more scientific.

(5) the interconnection between meeting room
① in the construction of a conference room and a slave, you only need to be the main meeting room AV (may also include control) signal on the "secondary" to the meeting room;
② in exactly the same as the equal status of conference rooms, AV signal interconnection and there are several ways:
* Videoconferencing device (or software forms of TV) for AV signal interconnect with each other;
* Through conventional wiring and audio and video switching to realize interconnection, audio and video synchronization is very important that you want to sound like one;
* Through digital audio media matrix or COBRANET technology audio interconnection.
Video of interconnection and including signal source and the scene in two ways. In today's multimedia conference rooms, simple video or audio interconnection, the value is not high, through audio and video matrix to realize interconnection and can only be limited to a smaller size, development trends, through video conferencing technology, particularly software PC-based video conferencing technology to enable AV interconnection.

4.4 room construction of things
(1) display area
Display is the focus of the modern room design, the study shows that 75% of the information from the eyes, the pursuit of big size display, high brightness display, high resolution display of process, scientific reason to return to the human eye viewing comfort for evaluation standard display system construction, the most important concept is the notion of image contrast — this means in practice is to use the actual use of comfort to evaluation is that users actually watch the image.
① According to the room size, display content, seating layout and lighting conditions to plan for your screen size and type;
② to coordinate the relationship between the illumination and display, especially front projection display;
③ selecting appropriate display technology.
(2) meeting of the speech and sound reinforcement
① According to room building structure, handle audio and acoustical, handle the decoration;
② room mainly consider loudness and language definition, some integrated conference rooms accommodate consider music and entertainment sound reinforcement;
③ reasonable under audio sources to select sound reinforcement – centralized or decentralized, etc.;
④ introduce advanced technology conference system and sound amplifying equipment.
(3) control
① total control planning to choose the right control equipment;
② attention to environmental control, particularly with the lighting of control;
③ use simple, reliable, friendly interface, no need for complex training.
(4) video broadcasting aspects
① Note color temperature selection;
② decoration colors should not be too much impact focus;
③ adopt digital storage devices;
④ for network transmission and playback.
(5) environmental aspects
① lighting;
② door management;
③ humidity management;
④ device control and elimination of noise;
⑤ meeting room office furniture selection.

4.5 standard specification for the system design
Current meeting room AV system is not a complete specification, but you can follow some of the corresponding technical specifications, for example in intelligent building design code provides for various types of intelligent building room should have basic functionality. In the display area, no national and international norms to follow, but there are some design theory and experience can follow, lighting and video conference connection both international standards and national standards to follow, and in a variety of sound reinforcement can refer to the Auditorium of the construction of a similar standard and meeting room.

4.6 users building flow
A good process, can greatly improve the efficiency and effectiveness and accelerate the progress of the project, in practice, we summarize the following construction process:
(1) research: mainly through information survey and actual visit, understand the present Conference room type and the technologies involved, through contact with a large number of designUnits and systems integration company, meeting room equipment manufacturers.
(2) determine the construction principle: in the construction of the common principles have practical principles, value for money, technology leading, featured, images and the integrated use of various principles.
(3) comb: repeated through internal discussions and numerous interactive design unit to determine the room location. Determine an experienced design units to help with needs analysis and design orientation is very important.
(4) according to the location and the total budget, experienced design units for decomposition design, making preliminary technical program.
(5) to the user and expert reviews, assessments and mainly technical programmes and objectives, strategies, positioning of the anastomosis, after correction technology programme, adapted to the tender documents.
(6) to select a qualified and associated experience in system integration units on offer.
