Low-bit rate motion JPEG using differential encoding

Motion JPEG (MJPEG) can be simply defined as a compression scheme in which each frame in a video sequence is JPEG compressed. This method though simple and intuitive has the disadvantages of high bandwidth requirements for transmission and low resilience to errors due to missing frames. In this paper, we present a modification to the MJPEG compression called MJPEG with differential pulse code modulation (MJPEG-DPCM) where differential encoding between coefficients of adjacent frames is carried out The modification provides higher compression, maintains perceptual visual quality and reduces video degradation due to missing frames or missing packets.
