Abstract
A content delivery system stores large content as frames of video that can be served by content servers already optimized for streaming video. Instead of storing image tiles in separate files, the system treats each tile as a frame of a video and stores the tiles in a video format. This allows transfer of large data from a publisher to a content server by transferring a single file or a small handful of files (rather than thousands or millions of files). Web servers such as MICROSOFT Internet Information Server (IIS) include smooth streaming support that can return individual images as video frames as though the images were stored in separate files. Thus, the content delivery system provides easier management of large data for publishers while continuing to provide a smooth experience consuming the data for clients.
