The development trend of multimedia technology is 1. Generally speaking, multimedia technology is developing in two directions: first, the development trend of networking, combined with broadband network communication and other technologies, makes multimedia technology enter the fields of scientific research and design, enterprise management, office automation, distance education, telemedicine, retrieval and consultation, culture and entertainment, automatic measurement and control and so on. Second, the multimedia terminal is componentized, intelligent and embedded, so as to improve the multimedia performance of the computer system itself and develop intelligent home appliances. In order to meet the challenge of international competition in the 2 1 century and the practice of educational reform, due to the progress of technology, especially the acceleration of the pace of informationization, this process of educational concept transformation is not only a process of ideological emancipation, but also a process of practice promotion. Digital technology has brought file processing into a new field, allowing people to make files at a faster speed, modify images and files in a more convenient way, and spread images and files to all directions quickly by using network communication. After digital compression, the problem of long-term preservation of video resources is fundamentally solved. When people in the future need something, they can call it up through the network, read it on the network terminal, and print it out from the terminal printer after they are satisfied. It is in this context that the Internet has unconsciously approached our lives. From 65438 to 0997, China media reported more and more on the Internet, and Internet information service providers began to operate commercially, which was reflected in the field of education. These technological changes have promoted the popularization of audio-visual education in schools. Many problems that were difficult to solve under the traditional educational means and methods in the past have been solved in today's digital way. 2. There is huge room for development. Advanced multimedia technology has a huge development space. PhilipsElectronics, a Dutch electronics manufacturing giant, said the day before yesterday that it was preparing to mass-produce a small display the size of a book, which would allow consumers to download newspapers and magazines and then roll them up for collection. This five-inch display can present fine images and can be folded into a pen-sized storage space. If it is connected to a mobile phone, it can also be used to download web pages, books or emails. Philips said that they developed this monochrome display using electronic circuits made of plastic. A spokesman for Philips Research Department said: "We will be able to mass-produce this display, which is no longer a research project. We will build a pilot production line, which is expected to be put into operation in 2005, when the annual output will reach 6.5438+0 million. " The pace of the times has brought us to the 2 1 century. Facing the information age, everything in the world is made up of information. Internet and commerce have become the topic of yesterday. People's work depends on information, and life depends on information. As one of the most traditional components in business activities, business cards still occupy history. Why is there no multimedia business card? Why is there no internet business card? Why is there no pda business card? Traditional business cards use paper as a medium to convey extremely limited information, such as name, phone number and company. For today's information age, this information seems a bit "shabby". It is impossible to introduce an individual or company in detail in a few words. How to express more content and complete corporate image in the form of business cards? Multimedia technology gives the answer. Sound, film and television, interaction, and even three-dimensional and four-dimensional elements are all expressed in the form of multimedia on business cards, which makes the application of multimedia technology more extensive. In fact, multimedia business cards are only the starting point of multimedia life. Advocating the diversification of multimedia can make multimedia not only be applied to multimedia CDs, but also make multimedia technologies and concepts really enter life and various fields under new technologies such as Bluetooth and pocket. Design and technology are equally important, and the key is to combine "pre-"design with "new" technology and use it in design. First of all, the concept of information modernization is applied in business activities. Secondly, popularize the art and technology of multimedia design and highlight the company image. At present, multimedia business cards or internet business cards have not been developed and designed as projects at home and abroad. Traditional business cards still dominate the world, only the company profile of multimedia CD. Taking multimedia business cards as a microcosm of multimedia applications, foreign countries should be ahead in multimedia applications, such as digital multimedia refrigerators and digital multimedia rooms. Although there is a certain gap between our software and hardware and foreign countries, we should catch up with them in concept. In 2003, ForresterResearch, a market research company, predicted that Apple would gain a share in this rapidly expanding market by entering the music download service market. In a research report released on May 6, 2005, the company predicted that by 2007, the value of European digital music download service market will reach1300 million euros. The income of this market in 2003 was only 24 million euros, but it will account for 13% of the total music sales revenue in 2007. By 2007, the market value of digital music download service in the United States will reach $2 billion. Forrester said that most of this revenue comes from personal downloads, not subscription-based services. The emergence of better legal services and higher broadband network penetration rate will promote this growth. RebeccaJennings, a research analyst, said that the recent news that EMI and Apple announced their entry into this market shows that major music companies and technology companies are now taking digital music in the future seriously. Although the legal music download market in the United States has got rid of obstacles and reached $65,438+0,500 million in 2002, the European market has fallen behind. This is because formal services are only concentrated in the United States, and the popularity of home broadband networks in Europe has been relatively slow. However, in the next few years, the spread of digital music will increase rapidly. The report predicts that consumer demand will force record companies to expand into the European market. The report shows that broadband users may download more MP3 music than narrowband users 123%. Jennings said that European consumers like to buy single records best. In 2002, Europeans bought about 65.438+65 billion single records, while American single records only sold 9 million. Jennings predicts that European consumers generally download single records, and 42% of digital music sales in Europe will be single records. In 2007, complete sets of records will account for 49% of downloaded music. Analysts say there are also subscription-based services. By 2007, 2 million users will pay 654.38+250 million euros for these services. In 1980s, Apple established a computer multimedia laboratory, which mainly studied the combination of computer technology and various information media, and introduced MACHITOSH system computer for the first time, marking the rise of early multimedia technology. In 1990s, the rapid development of multimedia computer technology brought a revolution to information dissemination. Modern multimedia, with the support of computer technology, not only has the inherent functions of memory storage, high-speed operation, logical judgment and self-running, but also adopts advanced means such as graphic window, interactive interface, voice recognition and touch screen, so that the computer not only has the ability to process text, graphics, audio and video, but also can vividly spread and express information in ways, images and sounds that people are used to and communicate with human beings. The wide application of multimedia technology has promoted the vigorous development of multimedia language laboratory, multimedia computer simulation laboratory, electronic library and multimedia teaching management. In addition, with the emergence and development of the Internet, network technology with the Internet as the main symbol constitutes an important part of modern science and technology culture. The Internet connecting hundreds of millions of people has brought mankind into a brand-new digital age and expanded the second living space of mankind-the network society. Under the background of network society, network technology and education are inextricably linked: the United States announced the Internet plan in 1998, announcing that every school, every classroom, every family and every American citizen can enjoy the brand-new learning environment brought by the Internet; The British government proposes to establish an online industrial university and launch a "national learning network", with the goal of connecting all 32,000 primary and secondary schools in Britain to the Internet by 2002. On 1999, China's Ministry of Education launched the action plan of education revitalization facing the 2 1 century, and put the construction of campus network on the agenda. In April 2000, China Basic Education Network was officially opened. In the same year, the Ministry of Education announced the full implementation of the "school-to-school communication" project, with the goal of making the country more than 90% in the next 5- 10 years. 3. The development of network teaching The combination of "multimedia" and "network" has contributed to the emergence of "multimedia network teaching". As a teaching medium in the information age, multimedia network technology has the characteristics of integration, interactivity, controllability, subjectivity and nonlinearity of information space, which makes it qualitatively different from traditional media such as blackboard, chalk and wall chart. The unique advantages of multimedia and network technology not only changed the teaching methods, but also had a far-reaching impact on traditional teaching, teaching mode, teaching content and teaching methods, which greatly impacted the "mass production" teaching in the era of machine industry. At present, this technology is developing in the direction of interactivity, nonlinearity, intelligence and globalization. 3. From the development trend of multimedia technology, the digitalization of multimedia technology will be the mainstream of future technology expansion, and as an important cornerstone of the existence and development of multimedia technology, digital multimedia chip technology will become the focus of future multimedia technology revolution. Whether it is the computer multimedia application based on PC technology, the multimedia realization of mobile communication services, and the multimedia integration of various electronic devices in the future 3C era, digital multimedia chips are undoubtedly the leading role.
