DivX is a digital video format that was developed by DivX Networks Inc. The DivX file format has found application in order to store high-resolution video after these files are compressed to a certain percentage of their initial size. At the same time, there is no need to talk about quality loss. When certain codecs are used, the files have a resolution of up to 1080 pixels. Moreover, they are able to occupy disk space up to 1 GB. DIVX files are media containers. They use audio and video codecs in order to increase compression efficiency, as well as in order to play data enclosed in a file of this format. There are two types of codecs used. In order to play .divx files, you need a DivX decompressor. DivX decompressors are included in most kits and packages. Many major media players have their own DivX support. DivX video files are also played by many hardware players. The lion's share of multimedia players can recognize the DIVX file type and open correctly to play .divx files. Only occasionally do you have to change the extension to .avi.
MPEG is a special standard for compressing audio files and video files into a different format, which is most convenient for downloading or forwarding, say, over a global network. The specified standard was developed by the Moving Picture Experts Group. It was created by the international organization ISO just in order to develop a standard for the compression and transmission of digital video and audio data. The official designation for this group is ISO / IEC JTC1 / SC29 WG11. The first time she met in Ottawa in May 1988. By 2005, up to 350 people became participants in the meetings. MPEG, that is, Moving Picture Experts Group, consists of 3 components: Audio, Video, System (combining and synchronizing the other two). There are different MPEG standards, which are also called phases: MPEG-1, MPEG-2, MPEG-3, MPEG-4, MPEG-7. According to the MPEG-1 standard, for example, streams of video and audio data are sent at a speed of 150 kilobytes per second. The speed of a single-speed CD-ROM player is similar. Streams are managed by sampling key video frames and filling in areas that change between frames. This standard ensures the quality of the video image is significantly lower compared to the video that is transmitted on the television standard.
