R&D Report 1996-03 : MPEG video coding: A basic tutorial introduction S.R. Ely MPEG has been outstandingly successful in defining standards for video compression coding, serving a wide range of applications, bit-rates, qualities and services on a worldwide basis. The standards are based upon a flexible toolkit of techniques for bit-rate reduction. MPEG video coding uses a combination of motion-compensated interframe prediction (for reducing temporal redundancy) with Discrete Cosine Transform (DCT) and variable length coding tools (for reducing spatial redundancy). The specification only defines the bitstream syntax and decoding process: the coding process is not specified and the performance of a coder will vary depending upon, for example, the quality of the motion-vector measurement, and the processes used for prediction-mode selection. * This Report is based on a European Broadcasting Union (EBU) Review item, from the EBU Review,Winter 1995 (Ed. 266), and is published with permission.
