What compression standard is mpeg?

mpeg is a compression standard for video, audio, and data. The MPEG standard mainly uses inter-frame compression coding technology with motion compensation to reduce temporal redundancy, uses DCT technology to reduce spatial redundancy of images, and uses entropy coding to reduce statistical redundancy in information representation. .

mpeg is a compression standard for video, audio, and data.

MPEG (Moving Picture Experts Group, Moving Picture Experts Group) is a specialized organization established in 1988 by ISO (International Standardization Organization, International Standardization Organization) and IEC (International Electrotechnical Commission, International Electrotechnical Commission). An organization that develops international standards for motion picture and speech compression.

This expert group is responsible for establishing video and audio standards for CDs, and its members are technical experts in the fields of video, audio and systems. Later, they successfully separated the recording of sound and images from the traditional analog method, established the ISO/IEC11172 compression coding standard, and formulated the MPEG-format, bringing audiovisual communication into the digital age.

Therefore, The MPEG-X version that everyone refers to now is the compression standard for video, audio, and data formulated and released by ISO (International Organization for Standardization).

The MPEG standard video compression coding technology mainly uses inter-frame compression coding technology with motion compensation to reduce temporal redundancy, and uses DCT technology to reduce the spatial redundancy of images. Entropy coding reduces statistical redundancy in information representation. The comprehensive application of these technologies greatly enhances compression performance.
