Yan'an Video Showcase latest offer

Video Showcase is a combination of various teaching software provides a convenient, flexible physical demonstration experiment, manuscripts, photographs, slides, negatives and the like. Optimize the teaching process in the teaching process, increasing classroom capacity, improve teaching efficiency and reduce the difficulty of teaching projection, reducing the labor intensity of teachers, by teachers of all ages. Video Showcase role in teaching more and more obvious, how should we buy this product, users have of how to maintain it, let's explore together. Now, with the widespread popularity of multimedia teaching equipment in schools designed specifically for educational presentations in a video booth products in this region it has been more widely used. But some people are still lack of understanding, the following, we introduce three typical use of video booth to show its actual application scenarios in education, hoping to give users more intuitive understanding. 1. take advantage of the physical features video projection booth can not scan images directly projected image screen, very convenient. Further, the exemplary process may be directly projected experimental operation. For example, observed with a microscope in biology class experiment can be carried out directly on the video booth demonstration operation, the students each position can be clearly seen; in addition, during the demonstration test of chemistry, physics and other disciplines have intuitive features, video booth careful observation can be intuitive, to bring students the deepest impression. 2. On the video booth directly writing on the blackboard blackboard direct projection booth with a video, very clear and intuitive. The industry has done a test: the same example, with chalk writing on the blackboard, computer gradually display, video projection booth + classic is tinted writing, these three means of comparison, finally, by the method of the video is a combination of performance and projection booth than the other two excellent. Because chalk writing on the blackboard behind the students see; computer displays like motion pictures, the students can not keep thinking; third method than the computer display a waste of time, but the actual effect is very good. Therefore, the actual situation of teaching, the use of video booth and direct manner compatible blackboard explaining the math, physics and other disciplines focusing on examples of the thinking process, is a good way of teaching. 3. Video booth old slide projector, slide video booth can accumulate a lot of old school slide, slide again, "Please glow Spring", the video booth backlight turned on, you can easily projection of these data, and , amplifying the effect higher than when using multiple projectors demonstrate the effect more clearly. In addition, now increasingly focused on interactive teaching, usually can already use video projection booth to the student's work on a blackboard, the teacher gradually correct the problem solving process for commenting, teaching effectiveness stronger. Through the introduction of the above points, the user may be able to video booth products have a certain understanding. With the continuous development of information technology in education, and continuously improve customer awareness, the video booth products will have greater development in the field of education. -4-Axis machining chuck lathe chuck shorten the processing cycle tower line - which patrol the line shall comply with safety regulations?

Note With the continuous development of information technology in education and the deepening of education reform, teachers' teaching methods are constantly changing. Many schools in the promotion of multimedia assisted teaching, before those high-end video booth has gradually entered into the ordinary classroom.

When using the remote control video Showcase, should try to make the remote control transmitter at the mouth of the remote video booth hosts receiving port, in order to achieve higher operating sensitivity; if you find the remote control does not work, then you first need to check the Are the remote control's batteries are charged, then sent to the remote control transmitter port and remote control video booth hosts receiving port wipe clean to avoid dust affect the remote control work if the remote control still does not work at this time, then re-confirm whether the current use of remote control and video showcase of the same model. 3, at the beginning of the use of video Showcase, the user should be based on different environment, to conduct some necessary adjustments to the operating parameters of video Showcase. For example, try to use the projector at the projection material, so that the video Showcase focusing and zooming and positioning of the projected image; Second, we must use the environment to the light conditions to adjust the brightness of the projector Video Showcase, contrast and color; s Three, also adjusted to accommodate different scanning frequency signal source, eliminate unstable image, only prepare the above, in order to make the video Showcase in top working condition. 4, the choice of video Showcase, in addition to interest resolution CCD technology such indicators, but also pay attention to the detection of a number of other indicators, such as black and white color reversal, reversing positive and negative film, the quality and quantity assist lamp sources , the number of input and output ports, whether the serial interface, whether an infrared remote control functions, etc., of course, choose these indicators are licensed under the premise of funds carried out. 5, when the video Showcase debug parameters, if found Video Showcase can not focus, it should first check close-up lens is attached to the CCD camera head; secondly look at the video Showcase whether the operation mode is in the auto focus mode, if is currently in the manual focus mode state, then it must be readjusted to the automatic mode condition; followed to ensure that the extendable rod in the correct position; you are confident that the above steps are normal, and Video Showcase still can not focus on it, we then carefully check the projection of the material itself is clear, or to see if there is dirt and stains on the projection lens cover, these reasons may cause the autofocus failure. 6, the choice of video Showcase, in order to ensure the stability and reliability of products, we should use a professional test cards for all aspects of the comparative evaluation of video Showcase, including the content of the test focused on the Visualizer accurate autofocus sex, color Showcase restore the true extent of the lens contour correction, lens focus and keystone uniformity, of course, we can also go directly to consult an experienced expert to help together to buy video showcase. 7, the use of video Showcase, in order to avoid unnecessary trouble, we should carefully read its instruction manual to learn safety rules video Showcase.
