Rapidly evolving computer and communications technologies have achieved data transmission rates and data storage capacities high enough for digital video. But video involves much more than just pushing bits! Achieving accurate color, smooth motion, and the best possible image quality requires understanding many aspects of image acquisition, coding, processing, and display that are outside the usual realm of computer graphics. At the same time, video system designers are facing new demands to interface with film and computer systems, and therefore need to understand many of the techniques of computer graphics. Digital Video and HDTV Algorithms and Interfaces covers the theory and engineering of digital video systems in a manner that is equally accessible to video engineers and computer graphics practitioners. It provides succinct and accurate treatment of standard-definition television (SDTV), high-definition television (HDTV), and compression systems. With the help of hundreds of high-quality technical illustrations and an extensive glossary, this book details the following topics: Basic concepts of digitization, sampling, quantization, gamma, and filtering; Principles of color science as applied to image capture and display; Scanning and coding of SDTV and HDTV; Video color coding: luma, chroma (4:2:2 component video, 4fsc composite video); Analog NTSC and PAL; Studio systems and interfaces, including SDI, IEEE 1394, and DV-over-1394; Digital videotape recording; Compression technology, including M-JPEG, DV, and MPEG-2; Broadcast standards (including digital television, DTV) and consumer video equipment.

Charles Poynton is an independent contractor specializing in the physics, mathematics, and engineering of digital color imaging systems, including digital video, HDTV, and digital cinema (D-cinema). In the early 1980s, Charles designed and built the digital video equipment used by NASA to convert video from the Space Shuttle into NTSC. In 1990, he initiated Sun Microsystems' HDTV research project, and introduced color management technology to Sun. He was responsible for Sun's founding membership in what later became the International Color Consortium (ICC). Charles was a key contributor to current digital video and HDTV studio standards. A Fellow of the Society of Motion Picture and Television Engineers (SMPTE), he was awarded the Society's prestigious David Sarnoff Gold Medal for his work to integrate video technology with computing and communications. Charles has taught many popular courses on video technology, HDTV, and color image coding, including many SIGGRAPH courses. He is the author of the widely respected book, A Technical Introduction to Digital Video, published in 1996. Charles lives in Toronto with his partner Barbara and their two girls, Quinn and Georgia. It is over their strenuous objections that he spells color without the u.
