   Basic technologies for information compression
   

When working with a digital video signal, it becomes necessary to process, transmit and store very large amounts of information. On modern media such as a CD-ROM (CD-ROM, 650 MB) or a hard disk (about a thousand megabytes), it is not possible to save a full-length video clip recorded in an element-by-element format. On the other hand, video information should be transmitted with the speed of its playback on the computer screen. For example, a full-color (24 bit / pixel) image of 720 × 576 pixels at a rate of 25 fps requires a video data transfer rate of 240 Mbit / s. However, the bandwidth of FDDI LAN channels is of the order of 100-200 Mbit / s, and Ethernet is only 10 Mbit / s. Therefore, the use of video data as a part of electronic products becomes impossible.

For frame-by-frame compression of video data, one can use compression algorithms for static graphics - lossy compression (JPEG). In this case, the restored image of a frame, as a rule, does not coincide with the original. However, the implementation of such algorithms is rather complicated and decoding processes require considerable time. Video information imposes specific limitations on the decoding speed of the data: the decoder (hardware / software device for decompressing data) must be able to decompress the image in 1/25 s, while the previous frame is displayed. This limitation does not make it possible to implement algorithms with a higher compression ratio.

Today, MPEG is a single format for the presentation of the United States

Grand Alliance HDTV specification data, the European Digital Video Broadcasting group and the Digital Versital Disc (DVD).

Three-dimensional models of real or abstract objects are created using specialized computer programs. 3D-modeling can be of the following types:

1. 
   Create photorealistic images, projected onto a conventional computer monitor or screen. Individual programs allow you to print the created model on a 3D printer.
   
2. 
   Creation of stereo images for viewing on a conventional computer monitor (screen) through special polarizing glasses or on a specialized 3D-monitor with stereoscopic effect.
   
3. 
   Creation of computer holograms.
