Multimedia refers to the integration of multiple media, generally including text, sound, images and other media forms. In computer systems, multimedia refers to a human-computer interactive information exchange and dissemination media that combines two or more media.
#Multimedia is a combination of multiple media, generally including text, sound, images and other media forms.
In computer systems, multimedia refers to a human-computer interactive information exchange and dissemination media that combines two or more media. The media used includes text, pictures, photos, sounds, animations and videos, as well as interactive features provided by the program.
Multimedia is a subset of the hypermedia system, which is a global information system composed of hyperlinks. The global information system uses the TCP/IP protocol and UDP on the Internet. /IP protocol application system.
Two-dimensional multimedia web pages are written in languages such as HTML and XML, and three-dimensional multimedia web pages are written in languages such as VRML. Many multimedia works are distributed using optical discs, and more and more online distribution will be used in the future.
Multimedia technology refers to the technology that uses computers to comprehensively process and manage text, data, graphics, images, animations, sounds and other media information, allowing users to interact with computers through multiple senses in real-time. , also known as computer multimedia technology.
Multimedia technology has the following main features:
(1) Integration: It can uniformly obtain, store, organize and synthesize information through multiple channels.
(2) Controlled multimedia technology is computer-centered, comprehensively processes and controls multimedia information, and displays it in a variety of media forms according to people's requirements, while acting on people's multiple senses.
(3) Interactivity Interactivity is one of the main features that distinguish multimedia applications from traditional information exchange media. Traditional information exchange media can only disseminate information one-way and passively, while multimedia technology can realize people's active selection and control of information.
(4) Non-linearity The non-linear characteristics of multimedia technology will change people’s traditional sequential reading and writing model. In the past, most people read and write using the framework of chapters, sections, and pages to acquire knowledge step by step. However, multimedia technology will use the method of Hyper Text Link to present content in a more flexible and changing way. to readers.
(5) Real-time performance When the user gives an operation command, the corresponding multimedia information can be controlled in real time.
(6) Interactivity, it can form an interaction between people and machines, people and people and machines, an operating environment and immersive scenes for mutual communication, and people can control it according to their needs. Human-machine communication is the biggest feature of multimedia.
(7) Convenience of information use Users can use information according to their own needs, interests, task requirements, preferences and cognitive characteristics, and use any form of information expression such as pictures, text, and sounds.
(8) Dynamic nature of information structure "Multimedia is a book that can never be finished". Users can reorganize information according to their own purposes and cognitive characteristics, add, delete or modify nodes, and re-establish Link.
Components of multimedia technology
Multimedia Technology (Multimedia Technology) is the use of computers to comprehensively process text, graphics, images, sounds, animations, videos and other information. Technology for establishing logical relationships and human-computer interaction.
The objects involved in real multimedia technology are the products of computer technology, while other simple things, such as movies, television, audio, etc., do not fall into the category of multimedia technology.
Media (medium) In the computer industry, media has two meanings: one refers to the carrier of information, such as language, text, images, video, audio, etc.; the other refers to the storage of information carriers, such as ROM, RAM, tapes, magnetic disks, optical discs, etc. The main carriers are CD-ROM, VCD, web pages, etc. Multimedia is a new thing that has emerged in recent years and is developing and improving rapidly.
Media in multimedia technology mainly refers to the former, which is to use computers to digitize media information such as text, graphics, images, animations, sounds and videos, and integrate them on a certain interactive interface. Give computers the ability to interactively display different media forms. It has greatly changed the traditional way people obtain information and conforms to the way people read in the information age.
The development of multimedia technology has changed the field of computer use, turning computers from special products in offices and laboratories into common tools in the information society. They are widely used in industrial production management, school education, and public information consulting. , commercial advertising, military command and training, and even family life and entertainment.
