Typical video ad networks for mobile use the CSS Sprites format to display in-line ads in a mobile web browser. The format makes sense in terms of allowing users to stay in a web browser while viewing video ads without switching to other video viewer apps. However, it displays a video clip consisting of independent still images in a manner similar to playing a flip book animation, its data volume being typically larger than that of QuickTime or MPEG video format because frame-to-frame delta compression is not applied.
