Abstract
Methods and systems for providing random access of structured media content are described. One aspect provides a novel file structure or “Vfile”, and method of using the same, for organizing and managing portions of a structured media content file that are or can be downloaded from a content provider such as a multimedia content server. The Vfile is configured to emulate a server file structure that a server uses to store structured media content files. The Vfile is established at a client location when a client accesses a structured media content file and is used to buffer and cache structured media content file portions. In addition, the Vfile includes one or more media management tags. The tags are used by the client to manage a cache of structured media content file portions that are downloaded from the server.
