With the development of information technology, multimedia technology is gradually applied to the education industry, which has brought great changes to the education industry. As an important part of it, education informatization has far-reaching implications for the entire society. Modern education is in an important period of transition from traditional education to quality education and from knowledge education to quality education. Therefore, the demand for educational information is becoming stronger and stronger.
Modern educational technology represented by multimedia technology is gradually being widely used in major colleges and universities. As a new type of information technology applied in the field of education, there are many application modes of educational informatization, including the construction of educational informatization network platforms, educational resource sharing, informatization construction, digital campus construction, and so on.
All these require the campus lecture hall to meet the campus’s needs for information construction and information sharing. As an information platform and service window open to the public, the lecture hall carries several special teaching contents and teaching tasks. The design of the lecture hall should have the characteristics of openness, safety, practicality, and convenience to provide a good environment and conditions for the development of the school. Under the premise of meeting the needs of the school’s informatization construction and meeting the school’s teaching tasks, the unique advantages of the lecture hall itself should be fully utilized. Create a good learning environment and conditions for students.
At present, the overall structure of the information system of the campus lecture hall is divided into two parts, namely the functional equipment part of the lecture hall and the network part of the lecture hall. The overall architecture can be divided into three layers according to functions, namely:
(1) Hall functional equipment: The main goal of the lecture hall system is to meet the functional requirements of the lecture hall, and to display rich and diverse information on the scene of the report through digital projection equipment. System integrators can provide technical support to ensure the quality of their services.
(2) Network part: It realizes the seamless connection between the system and other network systems, and supports the interconnection between network equipment and the network of the lecture hall. At present, many operators have formed a network information exchange platform and a network video surveillance platform. At the same time, the system can be connected to the school’s existing communication equipment.
(3) Switch part: To ensure the safe transmission and processing capability of the network, the system should have the security protection capability and reliability of network equipment and switches. The system integrator is responsible for the overall protocol configuration after access to the switch. By analyzing the hardware and software configuration provided by the switch, fully consider the cooperation between the devices and the system functions and interfaces that the switches need to consider, and finally form the communication protocol system between the modules in the system platform.
Q-NEX Solution can set up a centralized control system, connect a variety of conference equipment, can give full play to the role of multimedia, and improve conference quality. In addition, the system can flexibly set the number of devices according to meeting needs. Support one-key control switch, volume adjustment, matrix switching, etc. This system can not only provide a good communication effect for participants but also effectively improve the quality of the conference. It has rich conference management functions.
1. The design is scientific and reasonable
The design of the scientific lecture hall should follow the principles of science, rationality, simplicity, beauty, and practicality. The design plan of the lecture hall should be based on the content of the report meeting and the distribution of the report content, adopt a scientific and reasonable design, meet the actual use needs of the lecture hall, and ensure the accuracy and practicability of the report. In the design of the multimedia system, in addition to the arrangement of the multimedia equipment, the speaker should also take into account when reporting in the hall, and the screen content playback processing is required. Multimedia systems are divided into integrated systems and auxiliary systems according to their uses. The integrated system mainly includes lecture seats, lecture hall display equipment, and various information release equipment. The auxiliary system includes an information publishing station, multimedia information publishing station, various multimedia playing equipment, and other equipment.
2. Meet different functional requirements
Using NMP audio and visual equipment, the lecture hall can be combined according to the different needs of users to meet the individual needs of different users. As a multimedia application platform, the lecture hall can carry various functions such as conferences, lectures, and speeches; the lecture hall as a whole can realize a multi-functional display so that different functions can be integrated and shared.
Conference function: The conference is mainly conducted through multimedia interactive software, such as multimedia conference software “PPT conference” and “multi-person conference”. In the conference room, the real-time conference can be realized through multimedia projection, and the conference situation and conference status can also be displayed in real-time through the LCD computer.
Lecture function: multimedia and computer multimedia speeches are involved in the conference, and corresponding operations need to be completed in the lecture hall. The speech function can make the speaker understand the content of the speech more intuitively; at the same time, it can also meet the requirements of the live audience for interactive communication. It can provide the audience with a new and all-around display medium.
Report meeting function: According to the needs of users, the participants should give full play to their potential through image display. At the same time, the speech function can also meet the needs of multilingual communication with the speaker during the conference. And can realize a variety of voice functions according to user needs.
3. Easy to install and maintain
Multimedia conference rooms are usually installed in lecture halls with larger building areas. Installation is difficult. If it cannot meet the needs of users, it will affect the progress of the entire conference and affect the quality of the conference. To ensure the normal operation of the entire system, the Q-NEX solution can be used to control the conference audio system and multiple discrete systems through control. It has good reliability and stability through the corresponding design. to meet the conditions of use. This can help users reduce investment risks and create favorable conditions for the next step.
The main functions include:
① The control system can control the display screen and sound received by the computer through input or output signals. Including sound signal, video signal, and multimedia signal.
②The multimedia conference system supports the realization of control and management functions through the network: to realize the functions of remote control technology and remote control system equipment.
4. Easy to expand
The system can be upgraded and replaced at any time according to user needs. Moreover, supporting hardware and software upgrades also realizes seamless exchange and rapid updates between devices. The Q-NEX system has strong flexibility and scalability.
The openness and platform of the Q-NEX lecture hall system distinguish it from traditional lecture halls.
The advantages of high quality, high cost performance, easy installation and upgrade, easy maintenance, and convenient expansion can better meet the needs of teachers and students for modern education methods. With the rapid development of education, digital systems are often used in school construction projects in my country. to replace traditional equipment. This technology can greatly improve student learning efficiency. For the lecture hall, this can effectively improve the learning effect.
