MPEG-2 video compression

The DCT-based intrafield or intraframe compression at the heart of M-JPEG is suitable for video production; however, for distribution, dramatically higher compression ratios can be obtained by using interframe coding. MPEG-2 video compression exploits temporal coherence – the statistical likelihood that successive pictures in a video sequence are very similar. MPEG-2’s intended application ranges from below SD to beyond HD; the intended bit rate ranges from about 1.5 Mb/s to well over 20 Mb/s. MPEG-2 also defines audio compression, and provides for the transport of video with associated audio.

I assume that you are familiar with Introduction to video compression, on page 147, and with JPEG, M-JPEG, and DV, described ...
