Computer multimedia technology is the fastest developing and most active technology in the field of information technology, and it is also the focus of the development and competition of a new generation of electronic technology. Multimedia technology integrates many functions such as computer, sound, text, image, animation, video and communication. With the increasing popularity of high-speed information network, it can realize the global networking of computers and the sharing of information resources, so it is widely used in consulting services, books, education, communications, military affairs, finance, medical care and many other industries, and is subtly changing our life.
With the rapid development of computer multimedia technology, multimedia has been paid more and more attention and applied by people because of its own advantages, and has unconsciously affected many aspects of our lives. This paper briefly introduces the computer multimedia technology and its related concepts, and sums up the main applications of computers.
Multimedia computer should include hardware and software:
1, multimedia peripherals, including various media, audio-visual input and output devices and networks.
2. The multimedia computer has built-in hardware and control interface cards for various external devices. These include special circuit cards for real-time compression and decompression of multimedia.
3. Multimedia drivers and operating systems. This layer of software is the core of the system software. In addition to handling hardware devices (driving and controlling these devices), it also provides input and output control interfaces, that is, I/O interface programs. Operating system provides hardware and software control and management of multimedia computer.
4. Media production platform and media production tool software support application developers to create multimedia application software. Designers use the interfaces and tools provided by this layer to collect and produce media data. Commonly used are image design and editing system, animation production system, sound collection and editing system, video collection and editing system and multimedia public program.
5. Multimedia editing and creation system. This layer is the editing environment of multimedia application system, which usually has the function of controlling peripherals to play multimedia besides editing. Designers can use this layer of development tools and editing systems to create multimedia programs for various educational, entertainment, commercial and other applications.
6. The running platform of multimedia application system, namely multimedia playing system. This layer can play the contents of the hard disk on the computer, or independently play multimedia products, such as CD-I in consumer electronics. Multimedia application systems can be put into storage media such as CD-ROM, and become multimedia products and sold as commodities.
