Multimedia computer will accelerate the process of computer entering all aspects of family and society, and bring profound revolution to people's work, life and entertainment.

Extended data

The key technologies of multimedia mainly include the following points:

1, multimedia data compression/decompression technology:

Data compression algorithms are divided into lossless compression and lossy compression. Lossless compression is suitable for the case that the reconstructed signal is exactly the same as the original signal. A common example is the compression of disk files, which requires that no one can make mistakes after recovery. Lossy compression means that the reconstructed signal may not be exactly the same as the original signal. Lossy compression can be used for images, sounds and videos.

2. VLSI chip technology

3. Large-capacity optical disk storage technology: At present, popular carriers include CD-ROM (about 700 m), DVD (single-layer DVD is 4.7GB, double-layer DVD can reach 17GB) and flash disk (maximum 64GB).
