Basic TV Technology is the essential basic guide to the fundamentals underlying all television and video systems, written for students and nontechnical professionals. You don’t need to have a math or science background in order to understand this explanation of how the principal pieces of equipment work, what their functions are, and how they are integrated to form a complex video system. An understanding of this material will be necessary for you to succeed in the real world, where one person often has to perform many different roles and functions within a production. Armed with some basic technical background information, you’ll be more effective at figuring out new applications and at problem-solving. The fourth edition of Basic TV Technology has been updated to reflect the industry shift to digital video and includes new information on compression, television standards, LCD displays, HD, and equipment. This book features the accessible Media Manual format, in which every topic is covered in two pages: one of explanatory text and one of figures. *Gentle introduction to video technology*No science or math background necessary*Includes abundant illustrations
