Abstract: A system and method to increase the transparency of electronic work product created by one or more workers. The system and method consists of a development environment for each worker, wherein the environment records work being done along with appropriate metadata. The method provides and management tools to facilitate easy access and analysis of this data. The invention further generates work related event streams, which contain summaries of worker changes of particular interest to a given supervisor. These event streams are generated by the system and sent to the supervisor in real time, or almost real time, in the form of easy to read messages that can quickly let the supervisor see work progress at a glance.

Abstract: For use in media communications, e.g. in the delivery of video and audio or in teleconferencing, a media file or title is partitioned for secured, efficient delivery. A data sequence representing the file is partitioned into smaller subsequences, with a first subsequence being chosen to convey a degraded-quality representation of the data, and the other sequences for complementing the first subsequence to obtain a superior-quality representation. Among areas of applicability are media on demand, real-time communications and broadcasting, and online media locker, jukebox and chat room services.
