Digital Video Basics - analog &
digital TV basics and signal processing |
Course Description |
| Digital television is about re-invention of the television
industry via digital technology, just like digital computer
re-invented the computing and documenting industries. This course
is about Analog and Digital TV basics and relevant signal processing.
The course covers the fundamental technology that lies at the
heart of compression - particularly MPEG - and high definition
television (HDTV), and Digital TV in general. It is recommended
as an introductory course for the MPEG-2 or DTV course. |
Course Objectives |
| At the completion of this course, students will have a basic
understanding of how analog video is digitalized, carried, and
tested. Students will gain an understanding of the processes
involved in video encoding and decoding. They will be familiar
with the color space and colorimetry, gamma processing, etc.
Students will learn to identify common problems with digital
video quality, their causes, and solutions. In addition, students
will learn basic analog and digital video standards, principles
standards are based on and terminology. |
Who Should Attend |
| Although technical in content, this course is intended for
a wide audience. The course is designed for scientists, engineers,
analysts, and technical managers involved in the design, specification,
implementation, manufacturing, marketing, or evaluation of digital
video products or systems and others who wish to acquire knowledge
of the digital video technology field. |
