A system that converts information such as animation, video images, still images, audio, and text into digital data, processes them on a computer in a batch, combines them according to the user's wishes, and provides them effectively. In addition to personal computers, multimedia devices include various office systems such as video conferencing in business, and interactive televisions and high-performance videophones in the home. Currently, devices that read various information recorded on various media such as CD-ROMs and DVDs, and digital data obtained via networks such as the Internet, are being developed. This includes hypermedia, which allows interrelated multimedia information to be referenced on a computer. Various developments are also underway, including a method of digitizing a wide variety of information and storing it on large storage media, which can be used in each home via optical fiber with a transmission capacity of several gigabits per second. The term multimedia first appeared in the United States in the 1960s as a method of creating theaters using film, slides, and stereo sound, and has been widely used in its modern meaning since the 1980s.
