Motion Prediction in the GTV 2.0 Video Coder
by
Matt Renzelmann
In an uncompressed form, digital video is among the most storage- and
bandwidth-intensive applications of modern computers. The high degree of
redundancy among consecutive frames of such video, however, causes most of
these resources to be wasted. Motion prediction is one technique for
exploiting this redundancy, thereby allowing the video to be compressed more
effectively. We will discuss the principal ideas of motion prediction, with
an emphasis on the method used in our video coder, Group Testing for Video.
In particular, we will discuss the effect of interpolation, variable block
size prediction, and multiple reference frames. We will make comparisons
between our method and those used in standards such as H.263 and H.264.
