Multimedia electronic white principle

 Multimedia Whiteboard principle deemed Shenzhen record of professional introduce you to: principle of the basic concepts of media Multimedia Whiteboard (medium) in the computer industry, the media has two meanings: one refers to the dissemination of information carriers, such as language, writing, images, video, audio, etc.; the second refers to the stored information carrier, such as ROM, RAM, magnetic tape, magnetic disk, optical disk, etc., at present, the major carriers are CD-ROM, VCD, web pages and the like. Multimedia is a new thing in recent years by the emergence of, is booming and perfected. Multimedia technology we have mentioned in the media mainly refers to the former, is the use of computers to text, graphics, images, animation, audio and video and other digital media, information technology and integrate it in a certain interactive interface that allows The computer has the ability to interact show different forms of media. It greatly changed the traditional methods of access to information, in line with people in the information age reading. Development of multimedia technology has changed the field of use of the computer, so the computer from the office, laboratory and special products become common tools of the information society, widely used in industrial production management, school education, public information consulting, commercial, military command and training, and even family life and entertainment and other fields. Multimedia presentations usually computer application system can handle text, data and graphics information, and multimedia computer in addition to the above type of information processing, but also the integrated treatment of images, sounds, animation, video and other information, creating a new era of computer applications. Meaning that the application of multimedia technology: · allows the computer to handle human life is the most direct and most popular information, making computer applications and functionality has been greatly expanded. · Make computer systems and human-machine interface more friendly and convenient tools, non-professionals can easily use and operate the computer. Multimedia technology allows audio and video technology, computer technology and information processing technology, communications technology three closely together, laid a new foundation for the development of information processing technology. Multimedia technology has many years of history, the underlying technology so far sound, video, image compression has gradually matured and formed a product into the market, and now the popular techniques such as pattern recognition, MPEG compression technology, virtual reality technology is gradually matured, I believe that soon will enter the market. The multimedia content of the multimedia data compression technologies involved: Multi-modal conversion, compression coding; multimedia processing: processing the audio information such as music synthesis, speech recognition, text and voice conversion; image processing, virtual reality; multimedia data storage: multimedia database; Multimedia data retrieval: content-based image retrieval, video retrieval; multimedia authoring tools: multimedia synchronization, hypermedia and hypertext; multimedia communications and distributed multimedia: CSCW, conference systems, VOD and system design; multimedia equipment technology: multimedia special chip technology, multimedia dedicated input-output technology; multimedia application technology: CAI and distance learning, GIS and Digital Earth, multimedia remote monitoring. Multimedia technology multimedia technology covers a wide range, including: ? Audio technology: audio sample, compression, synthesis and processing, speech recognition. · Video technology: video digitizing and processing. * Image Technology: image processing, image, graphics, generated dynamically. · Image compression technology: image compression, dynamic video compression. ? Communication technology: voice, video, image transmission. Standardized: multimedia standardization. The basic types (1) Text Text is based on information in the form of text and a variety of special symbols expressed, it is most frequently used in real life an information storage and transfer mode. Expression of information gives sufficient imagination with text, it is mainly used for descriptive representation of knowledge, as set forth concepts, definitions, principles and issues, and display titles, menu and so on. (2) The image of the image is one of the most important multimedia software information manifestation, it was decided a multimedia visual effects software key factor. (3) Animation Animation is the use of human visual persistence characteristics, play a series of rapid changes continuously moving graphic images, including zoom pictures, rotate, transform, fade and other special effects. By animation you can visualize the abstract content, teaching content of many interesting changes difficult to understand. Rational use of animation can achieve a multiplier effect. (4) The sound is that people used to convey information, feel the most convenient and most familiar way. Multimedia courseware, its forms of expression, the sound can be divided into talks, music, effects categories. (5) video image video image with the timing of the wealth of information and content, commonly used in the development process to explain things. Video is very similar to our well-known film and television, sound and color, served as an important role in multimedia. In Shenzhen deemed Chong (WWW.CTVHD.CN) Technology Co., Ltd. is committed to video, teaching, touch devices product development, production, sales and service, specializing in the production of teaching one machine, LCD whiteboard, one PC, touch TV PC one, touch one, touch LCD advertising machine.
