Refers to electronically capturing, recording, processing (manipulating) storing, transmitting, and displaying a sequence of still images recorded many times a second to produce scenes in motion.

It is in a format that can be presented on television ( or on any video supporting device for that matter).

A video mainly consists of:- Still images ( image frames)- Audio Source: Webopedia.com and Wikipedia.com

Still Images to make the video you just viewed.

Sampling Rate: It’s the number of measurements taken every second.In terms of video and audio, the more accurate “digitized” sound or

video , the higher the sampling rate and thereby more data measurements to be collected.

Audio Sampling Rate

• Sample size refers to the capacity of a video data.

• It is a representation of units to be sampled that holds the statistical information of video data.

• Frame Rate: The Frequency [rate] at which an imaging device produces “unique” consecutive images called frames. Source: Wikipedia.com• In short, frame rate are the number of frames which are shown in a second. • There are a number of different frame rates which are used in television, movies etc… They include:• i- stands for “interlaced fields” , so 50i= 25 frames•p- stands for “noninterlaced fields”. So 50p= 50 frames* Interlaced: Increase quality of video without bandwidth

The Frame Rate

•Video data consists of the main components of framework- images being recorded into still frames and the recording of audio through a microphone in the camera. Video data is a representation of images that move or change. This also includes the various forms of animation.

• Video data is a sequence of measurements which includes the color and brightness that is been detected by individual light collection points in a digital video camera or video signal through a traditional video camera or VCR.

• The measurements of video data characterizes the pixels of an image in a single frame. This may reach up to 30 frames of data per second that is been processed. The process of video data makes it the most complicated and largest of the 5 data types.
