Abstract

A method is provided for maximizing utility of a media delivery network having a media source, a first media adaptor, a second media adaptor and a media renderer. The media source can provide data in a first format and a second format. The first media adaptor can receive the data in the first format from the media source. The second media adaptor can receive the data in the second format from the media source. The first media adaptor can further provide data in a third format based on the received data in the first format. The second media adaptor can further provide data in a fourth format based on the received data in the second format. The media renderer can render the data in the third format and can render the data in the fourth format. The method includes: defining constraints of the media delivery network; predetermining factors to measure a utility of the media delivery network; defining a utility function based on the predetermined factors; and maximizing the utility function in light of the defined constraints.
