Background technique

In the past, the main purpose of computers was to perform complex and repetitive calculation tasks. With the change of technological trends, most of the current computers are multimedia computers that integrate sound cards, CD-ROM drives, speakers and microphones. The rapid development of system and multimedia technology enables computers to play music (for example, play music in file formats such as WAV, MIDI, MP3..., or play music CDs) and play movies (for example, play MPEG, AVI, ASF, RM... and other file formats, or play audio-visual discs) for audio-visual entertainment.

General multimedia equipment (for example, TV, radio, audio-visual disc, etc.) can be used immediately as long as it is turned on, and there is no need to wait for a long turn-on time. However, if you want to use a computer to play multimedia data (pictures, music, movies, etc.), you must first start the computer, and load the general operating system (for example, Windows operating system, Linux operating system, etc.) that the computer needs to operate. system, Macintosh operating system... etc.), and then execute the multimedia application to play the multimedia data. Depending on the grade of the computer (the clock frequency of the CPU, the amount of memory, the transmission speed of the data bus, etc.), the time required for the computer to start is also different, but on average, at least 1-2 minutes of waiting time is required.

Although a multimedia computer can provide audio-visual entertainment effects, its multimedia playback function is based on the existing operating system. It is enough to operate the core of the operating system of the multimedia equipment on the computer.
