Résumé

From the fundamentals of video recorders, to the latest advances in disk recording, DVD, and optical techniques, here is your one-stop guide to understanding the technical details and applications associated with video recording technology. Authored by a foremost authority in the field, this up-to-date, comprehensive reference covers the entire range of the technology, from home and professional models ? to tape and disk recorders ? to the recent transition from analog to digital products. It helps you understand how the technology is applied to broadcasting, computers, telecommunications, and more.

Video and broadcast engineers will want to have this book close at hand, but even if your engineering or computer background is not video-specific, you?ll value this clearly written, easy-to-follow guide that helps you increase your understanding of recorder formats, heads and scanners, tape decks, disk drives, signal processing, editing, various recorder products, and much more.

Contents: Video Fundamentals. Recording Fundamentals. Tapes, Disks, and Records. Heads and Helical Scanners. Tape Decks. Disk Drives. Recorder Signal Processing. Editing. Recorder System Features. Tape Recorder Products. Disk Recorder Products. Trends in Recording. Glossary.

Arch C. Luther is president of Arch Luther Associates in Jenner, California. He earned his B.S. in electrical engineering from the Massachusetts Institute of Technology. Mr. Luther holds 32 patents gained during his 38-year career in broadcast engineering at RCA, and is the author of ten books, including Video Camera Technology and Principles of Digital Audio and Video, both published by Artech House. He has won both the SMPTE David Sarnoff Gold Medal and RCA David Sarnoff Gold Medal for Outstanding Technical Achievement.
