2.2.2 large conference hall with simultaneous interpretation system
Simultaneous interpretation system in acoustic (spokesman) audio expansion on the system on the basis of the signal through the device will send the interpreter in the workplace, through a number of different languages for simultaneous translation, an interpreter through wired or wireless devices are sent to the scene of the meeting have different language requirements represent the wearing headphones, Conference control receiving device to select the desired languages. Language translation can be directly translated and quadratic form of translation. Simultaneous interpretation system can better meet the multilingual international meeting the demand for different countries or nationalities of participants to each other quickly and easily exchange and discussion purposes.
Simultaneous interpretation system comprises the following main parts: System control unit, Chairman of the meeting and on behalf of the unit, simultaneous translation unit and expansion units and ancillary equipment. Diagram shown in Figure 2. A brief
Simultaneous interpretation system intends to use Philips (Philip) product that can meet the modern requirements for Multilingual conferences. It is the use of a modular structure of series products, according to the actual requirements appropriate to expand or reduce the size and configuration of the system to adapt to different conference events. This system is mainly composed of desk and DCN in languages and transliterated transmission equipment, with a dedicated control handle DCN software.
In DCN system, language distribution, you can use wired or wirelessly. Wired language distribution system using DCN trunk cable distribution to the participants in the Conference languages. You can receive the channel selector or equipped with channel selector speech equipment headset languages. Used as row or retrograde choice keys to quickly find the language you want to hear. Language selection automatically to enable language channels. Wireless infrared system in the venue for the wireless transmission, excellent sound quality, while at the same time as the flow of personnel provides great convenience, you can transfer a maximum of 16 channels. Because infrared cannot penetrate the walls of the rooms, so the degree of confidentiality can be guaranteed to be able to receive infrared system on behalf of the receiver on the number in principle is not restricted. This system is intended to be used for cable routing.
In this scenario design reference for Philips simultaneous interpretation and language distribution system, the selection of the desk is LBB3520/00 type, its main features are: with LCD; suitable for 15 languages; preset keys to select the language; have the quality of the input language.
LBB3520/00 is the role of an interpreter single, consistent with the international table. This advanced technology, elegant microprocessor-controlled device can receive 14 language channel, plus a statement of the original languages. Each workshop can hold six desk, LCD display languages and other relevant information.
2.2.3 video conference system
Videoconferencing system (VideoConferencingSystem) is a Visual, sound-based interactive multimedia digital communication system. It uses modern high-speed development of image and audio communications technology, computer and microelectronic technology, for text areas or remote areas between points or more between two-way video, audio, data, information and interactive real-time communication. Meeting TV system can be separated by two or more placesPoint of the Conference room TV devices connected together so that the participants have come together for a meeting, face to face to discuss the meeting agenda, on issues of concern to everyone. in-kind, pictures, charts, or engineering drawings, upon request, provide to the participants, static graphic file fax etc. assisted projects. It can be used for all types of administrative meetings, scientific meetings, technical exchanges, business negotiations, is to achieve efficient Conference Office of modernization tools.
