Computer video has many faces: it includes watching TV shows, digital videos, and security systems. This publication covers almost all aspects of this area of modern technology - from the initial stages of digitization to retouching of the resulting frames and from the simplest frame capture cards to non-linear editing systems. The purpose of the book is to enable anyone, even an inexperienced user, to independently select, install and configure the equipment and programs they need. Much attention is paid to devices for home use: TV tuners, including external ones, as well as simple digital video recording systems. A special section is dedicated to the rapidly growing popularity of the DVD format. In addition to describing specific devices and software, theoretical data necessary to prevent possible problems is presented. For the first time in a popular form, the use of computer video in security systems is considered and a detailed overview of existing systems on the market is given. The book is intended for beginners and experienced users who have not previously encountered installing and configuring computer video systems. Some sections may also be useful for professionals as reference material.
