This article mainly introduces what format mpeg refers to, the article is very detailed, has a certain reference value, interested friends must read it!

Mpeg is a video format. MPEG standard video compression coding technology mainly uses interframe compression coding technology with motion compensation to reduce time redundancy, DCT technology to reduce image spatial redundancy, and entropy coding to reduce statistical redundancy in information representation.

Mpeg is a video format.

Some experts separate the recording of sound and video from the traditional analog method, establish the ISO/IEC11172 compression coding standard, and develop the MPEG- format, which makes the audio-visual communication enter the digital era. The MPEG-X version that you are generally referring to is the compression standard for video, audio and data developed and released by ISO.

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

Extended data:

Advantages of MPEG format:

1. The algorithm is designed especially for the conditions such as low bandwidth, so the compression ratio of MPEG4 is higher, which makes the video transmission with low bit rate possible. Video can be transmitted continuously on the public phone line and the quality of the image can be maintained, which can not be done by other technologies.

2. Save storage space. Under the same conditions such as scene, image format and compression resolution, the smaller the encoded image file is, the smaller the storage space is. Because MPEG-4 algorithm is more optimized than MPEG-1 and MPEG-2, it has higher compression efficiency.

3. The image quality is good. The highest image definition of MPEG4 is 768X576, which is much better than 352X288 of MPEG1, and can achieve the picture effect close to DVD. This makes its high-definition image very good.
