MT1: UNIT 2 VIDEO-Elements of multimedia

A still image is a spatial distribution of intensity that is constant with respect to time. Video, on the other hand, is a spatial intensity pattern that changes with time. Another common term for video is image sequence, since video can be represented by a time sequence of still images. Video has traditionally been captured, stored and transmitted in analog form. The term analog video signal refers to a one-dimensional (1-D) electrical signal of time that is obtained by sampling the video intensity pattern in the vertical and temporal coordinates and converting intensity to electrical representation. The unit will equally analyse the principles and application of video. 2.0 OBJECTIVES At the end of this unit, you should be able to: Describe the features of a Video Explain the need of a Video in the Multimedia System
