Abstract

A streaming media delivery system employs multiple client data networks storing copies of the streaming media. When a viewer wishes to see content, the system chooses a client data network which is best for providing the media content and directs a client wrapper object on the viewer's system to that network. When the quality of delivery from that network becomes too low, a client wrapper object on the viewer's system can request a switchover to a new client data network. The system may also redirect the wrapper object to receive content from a different network for maintenance purposes and the like. The viewer wrapper object also provides monitoring information on communication line quality and the like to the system for feedback and logging purposes.
