Abstract

A system and method supporting access to multimedia information based upon user-defined quality of service criteria is disclosed. A broadband access gateway may coordinate network behavior during the transition of an access device among communication pathways having different available capacities. Adjustments in bit rates and levels of compression may be made based upon the user-defined quality of service criteria. The user may be notified when network conditions disallow support for the desired quality of service, and may choose to override selected criteria. The user-defined quality of service criteria may be stored within the gateway and associated with a user, or may be located in the access device and accessible to the gateway.
