電子圖書:閉路電視監控技術安全指南。
The effects of digital technology on the security industry require
constant vigilance by security distributors, sales staff, and
installation professionals. Today and for the foreseeable future, all
security professionals must have at least a basic understanding of
digital technology. Digital CCTV addresses this new challenge. Topics
convered include compression variables such as Lossless and Lossy, which
are explained by reviewing Huffman and Run Length Encoding (RLE), and by
relating these forms of compression to ZIP and Stuffit, which are
commonly used in personal computers. A review of JPEG, motion JPEG, MPEG
and wavelet compression schemes among others, with a comparison of the
merits of each, is also provided. As Digital CCTV traces the stream of
digital video flow from the computer industry through compression,
transmission, display and storage, and explains how analog video signal
is converted into a digital signal, the reader will learn and understand
the mysteries of digital science.
