【简　介】:This book is on real-time video compression. Specifically, the book introduces the XYZ video
compression technique, that operates in three dimensions, eliminating the overhead of motion
estimation. First, video compression standards, MPEG and H.261/H.263, are described. They both
use asymmetric compression algorithms, based on motion estimation. Their encoders are much more
complex than decoders. The XYZ technique uses a symmetric algorithm, based on the Three-
Dimensional Discrete Cosine Transform (3D-DCT). 3D-DCT was originally suggested for
compression about twenty years ago, however at that time the computational complexity of the
algorithm was to high, it required large buffer memory, and was not as effective as motion
estimation. We have resurrected the 3D-DCT based video compression algorithm by developing
several enhancements to the original algorithm. These enhancements made the algorithm feasible for
real-time video compression in applications such as video-on-demand, interactive multimedia, and
videoconferencing. The demonstrated results, presented in the book, suggest that the XYZ video
compression technique is not only a fast algorithm, but also provides superior compression ratios and
high quality of the video compared to existing standard techniques, such as MPEG and H.261/H.263.
The elegance of the XYZ technique is in its simplicity, which leads to inexpensive VLSI
implementation of a XYZ codec.
