What is the difference between H.264 and MJ compression?

Release time:2014-5-14 14:49:53 Source: Lang cloud technology

The essential difference between MJPEG and H.264 video compression methods is the algorithms used. The MJPEG image is compressed sequentially, frame by frame, and it is transmitted like that through the network. Each transmitted frame is processed independently, so it is sent frame by frame to the destination and then connected into one flawless video. H.264 or MPEG4 part 10 (AVC) is the latest video compression format used in vast variety of video equipment. Fundamental principles are: relatively full or Key frames are transmitted periodically and between them information is transmitted only on the changed part of the image. These unique features significantly reduces the amount of transmitted and recorded data while maintaining a similar quality to MJPEG, but at the same time requires a significant amount of CPU resources for video encoding and decoding.
