This chapter discusses video basics. In this regard, we will first look at image formation and colour video. Interlaced/progressive video is explained, and its impact on the signal bandwidth and display units is discussed. Representation of video in digital form and the need for bit rate reductions will be addressed. Finally, the image formats to be coded for various applications and their quality assessments will be analysed.
