MPC means Multimedia Personal Computer. It defines minimum standards for different levels of multimedia PCs. These standards define the minimum hardware and software requirements for different levels. Nowadays there are three levels and in the list below you can find the definition of those levels, copied form this link.
The best is the MPC 3. In this level, the PC should be able to play MPEG-1 352 * 240 at 30 frame/sec or 352 * 288 at 25 frames/sec.
Digital Video Interactive is basically a hardware based compression/decompression algorithm for coding video data. It was developed by General Electric in the 80's. Intel bought this technology and developed a software based version of DVI, called Indeo. A DVI-file (.dvi) can nowadays contain audio, video, images, graphics and text. The DVI - format is usually used similar to PostScript; for storing documents and printing them. There are dvi - drives for printers (Canon) although these are not very common. On the UNIX side there is a program called xdvi for viewing dvi - documents. Indeo, which is Intel's software drive, is used for capturing, compressing and decompressing digital video data to be used in PCs. Microsoft uses an Indeo-driver for playing video clips in the Video for Windows (.avi) format. It only contains audio and video data which is compressed according to the DVI compression specifications.
QuickTime is produced by Apple. It was originally used in Apple-computers, like the Macintosh, to store digital image, audio and video data. Nowaydays a QuickTime-file can contain audio, video, image, music, text and graphics. There is also a player for Windows: Quicktime for Windows 2.0. The players support at least the following image & video formats: JPEG, MPEG, CinePak and DVI.In other words, it is now a real multimedia platform. QuickTime, MPEG and DVI (specially .avi) are the main digital video formats used on the Internet.
