Multimedia is a synthesis of multiple media, generally including various forms of media such as text, sound, and images.

In computer systems, multimedia refers to a human-computer interactive communication and dissemination medium that combines two or more media. The media used includes text, images, photos, sounds, animations, and videos, as well as interactive features provided by the program.

summary

Multimedia technology is a technology that stores and manages various information such as language, text, data, audio, and video through computers, enabling users to communicate real-time information with computers through multiple senses. The content displayed and carried by multimedia technology is actually a product of computer technology.

Our so-called media refers to the carrier that carries and transmits certain information or materials. It can be divided into five categories: sensory media, expressive media, performance media, storage media, and transmission media. In the field of computer science, media is mainly a carrier for transmitting and storing information, including language, text, data, video, audio, and so on; The storage carriers include hard disks, floppy disks, magnetic tapes, magnetic disks, optical disks, and so on. Multimedia is the scientific integration of various media functions, working together to provide users with various forms of information presentation, resulting in more intuitive and vivid information.

Multimedia technology is the use of computers to digitize media information such as textual materials, visual materials, audio, and video, and integrate them into interactive interfaces, giving computers the ability to interactively display different forms of media.

development

Multimedia technology can be said to be a typical representative product in the information age. Initially, multimedia technology was developed in the military field, achieving military objectives through multimedia joint display. Subsequently, this technology rapidly developed due to its excellent information processing and transmission capabilities, and received high attention from research institutions. Through research and application, it gradually formed a key way of information exchange. In the 21st century, multimedia technology has developed at a faster pace, greatly changing the traditional way people obtain information and catering to their needs for reading information. The development of multimedia technology has promoted changes in the use of computers, moving them out of offices and laboratories, expanding their vast applicability, and entering many fields of human social activities, including industrial production management, school education, public information consulting, commercial advertising, military command and training, and even family life and entertainment. They have been widely used and become a universal tool in the information society.

Multimedia Features

Multimedia technology has the following main characteristics:

(1) Integration enables multi-channel unified acquisition, storage, organization, and synthesis of information.

(2) Controlled multimedia technology is centered around computers, which comprehensively processes and controls multimedia information, and presents it in various media forms according to human requirements, while acting on multiple senses of humans.

(3) Interactivity is one of the main characteristics that distinguish multimedia applications from traditional information communication media. Traditional information communication media can only passively and unidirectionally disseminate information, while multimedia technology can enable people to actively choose and control information.

(4) The non-linear characteristics of non-linear multimedia technology will change people's traditional sequential reading and writing mode. In the past, people's reading and writing methods mostly used the framework of chapters, sections, and pages to gradually acquire knowledge, while multimedia technology will use the method of Hyper Text Link to present content to readers in a more flexible and varied way.

(5) Real time: When the user gives an operation command, the corresponding multimedia information can be controlled in real-time.

(6) Interactivity, it can create an interactive operating environment and immersive scene for people to interact with machines, people to people and machines to communicate with each other, and people to control according to their needs. Human computer interaction is the biggest feature of multimedia.

(7) The convenience of information use allows users to use information according to their own needs, interests, task requirements, preferences, and cognitive characteristics, in any form such as images, text, sound, etc.

(8) The dynamism of information structure means that multimedia is an endless book, and users can reorganize information, add, delete, or modify nodes, and re-establish links according to their own purposes and cognitive characteristics.
