This paper presents the design, implementation, and validation of a novel system that supports streaming and playout of personalized, multi-path, nonlinear video. In contrast to regular video, in which the file content is played sequentially, our design allow multiple nonlinear video sequences to be stitched together and played in any personalized order, and clients can be provided multiple path choices. Regardless of selected playback sequences and path choices, our design allows the video to be seamlessly viewed such as to provide uninterrupted playback. The design combines the ideas of HTTP-based adaptive streaming and multi-path nonlinear video. Personalization of the content is achieved with the use of a customized metafile, which is downloaded separately from the media files themselves. A simple extension to the user interface allows path choices to be presented to and made by the user. Novel buffer management and prefetching policies are used to ensure seamless playback even under scenarios in which clients defer their path choices until the last possible moment. Our solution is simple, allows creative home users to easily create their own multi-path video and/or multi-path version of existing videos, and opens the door for user-generated multi-path video; creating an endless possibility of new opportunities and media forms.
