By John Watkinson, Reading, UK International consultant in audio, video and data recording.
Description The industry "bible" is back and it's better than ever. The Art of Digital Video has served as the ultimate reference guide for those
working with digital video for generations. Now this classic has been revised and re-written by international consultant and industry
leader John Watkinson to include important technical updates on this ever-evolving topic.
The format has also been improved to include
optional sections that provide additional information that you can choose to skip or investigate further, depending on your interests
and comfort level with the subject. As the worlds of film, digital imaging, and computing have converged, this book has evolved to remain
current and relevant, while still remaining the classic that experts in the field have trusted for years.
Audience
Professionals in video engineering, electrical engineering, broadcast and communications engineering, computing personnel now working
in communications/broadcasting technology. Personnel in digital video companies. Technical libraries, lecturers, and students on broadcast
and communications courses.
