What format is MPEG?

The MPEG standard mainly has the following five, MPEG-1, MPEG-2, MPEG-4, MPEG-7 and MPEG-21 and so on. Established in 1988, the expert is responsible for establishing video and audio standards for CDs, while members are technical experts in the video, audio, and systems sectors. After that, they successfully separated the sound and image records from the traditional analog mode, established the iso/iec1172 compression coding standard, and worked out the mpeg-format to make the audio-visual communication into the digital era. Therefore, the Mpeg-x version, which is generally referred to by the ISO (International Organization for Standardization), is a compression standard for video, audio and data.

The MPEG standard video compression coding technology mainly utilizes the motion compensation frame compression coding technology to reduce the time redundancy, uses the DCT technology to reduce the spatial redundancy of the image, and uses the entropy coding to reduce the statistic redundancy in the information representation. The comprehensive application of these technologies greatly enhances the compression performance.
