商品描述

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.

* Explains industry concepts, acronyms and buzzwords acurately and clearly
* Covers history, current complexities, and the future effects of digital science
*Provides practical information about how digital video works, how digital video is stored and transmitted, what digital systems can and cannot accomplish, and what to expect from digital video equipment in modern CCTV systems

商品描述(中文翻譯)

數位科技對安全產業的影響需要安全分銷商、銷售人員和安裝專業人員保持持續的警覺。今天及可預見的未來,所有安全專業人員必須至少具備基本的數位科技知識。《數位監視器 (Digital CCTV)》針對這一新挑戰進行了探討。

涵蓋的主題包括壓縮變數,如無損壓縮 (Lossless) 和有損壓縮 (Lossy),這些概念通過回顧霍夫曼編碼 (Huffman) 和行程長度編碼 (Run Length Encoding, RLE) 來解釋,並將這些壓縮形式與在個人電腦中常用的 ZIP 和 Stuffit 進行關聯。此外,還提供了 JPEG、動態 JPEG、MPEG 和小波壓縮方案等的回顧,並比較了各自的優缺點。《數位監視器 (Digital CCTV)》追溯了數位視頻流從計算機產業經過壓縮、傳輸、顯示和存儲的過程,並解釋了模擬視頻信號如何轉換為數位信號,讀者將學習並理解數位科學的奧秘。

* 準確且清晰地解釋行業概念、縮寫和流行術語
* 涵蓋歷史、當前的複雜性以及數位科學的未來影響
* 提供有關數位視頻如何運作、如何存儲和傳輸數位視頻、數位系統能夠和無法實現的功能,以及現代 CCTV 系統中數位視頻設備的預期表現的實用資訊
