Abstract: Media content can be synchronized across multiple participant devices. A set of participant devices may request access to stream media content from a content delivery network. Each participant device can send information relating to the playback of the media content to a coordination server. The coordination server can determine a synchronized time for playback of the media content such that all participant devices playback the media content simultaneously. The coordination server can instruct each participant device to playback the media content according to the synchronized time.

Abstract: A computer-implemented method is provided for managing and sharing picture files. In one embodiment of the present invention, the method comprises providing a server platform and providing a datastore on the server platform for maintaining full resolution copies of the files shared between a plurality of sharing clients. A synchronization engine is provided on the server platform and is configured to send real-time updates to a plurality of sharing clients when at least one of the sharing clients updates or changes one of said files. A web interface may also be provided that allows a user to access files in the datastore through the use of a web browser.
