Document Summary

A sequence of sill images (photographs) that create the illusion of movement when played in succession. Digital video each frame is a bitmapped graphic, stored as 0s and 1s. Since each frame is just an image . Each frame is sampled into a discrete samples and each sample becomes a pixel . More samples means beter quality (10 pixels by 10 pixels vs 200 pixels by 200 pixels) More samples means bigger ile sizes (10 pixels by 10 pixels vs 200 pixels by 200 pixels) Each pixel gets assigned a colour, maybe just 2 colours(black and white 1bit colour) or maybe 16 million colour (24 bit colour) quanizaion process. For sill images rgb is commonly used. For video the model is yuv (yiq) or ycbcr (for mpeg compression) Uv (cbcr) chrominance (color/hue) digital video oten adheres to standards for tv broadcasing. Regular analog tv broadcasing began in the united states in 1939 using the ntsc standard.
