There are four sequences of images in MPEG architectures,namely I-Frame, P-Frame, B-Frame, and D-Frame. The four frames are distinguished by compression. I-Frame is compressed independently of other images with intraframe compression method.P-frame motion compensation compressed by the method of I-Frame or P-Frame before.Meanwhile, B-Frame is compressed using bi-directional
prediction based on interpolation of the I-Frame or P-Frame previously
