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.

3. The method of claim 1, wherein said predetermining factors to measure a utility of the media delivery network further comprises predetermining at least one of resource usage ratio, device dependent satisfaction and network flow of an associated data stream.

4. The method of claim 1, wherein said arranging the media renderer to receive one of the first received data and the second received data based on the maximized utility function comprises enabling one of the first media adaptor to provide data in the third format and the second media adaptor to provide data in the fourth format and preventing the other of the second media adaptor to provide data in the fourth format and the first media adaptor to provide data in the third format.

5. A method of maximizing utility of a media delivery network, said method comprising:

defining constraints of the media delivery network, the media delivery network having a first media source, a second media source, a media adaptor and a media renderer, the first media source being operable to provide first data in a first format, the second media source being operable to provide second data in a second format, the media adaptor being operable to receive the first data in the first format from the first media source and to receive the second data in the second format from the second media source, the media adaptor being operable to provide data in a third format based on the received first data in the first format and to provide data in a fourth format based on the received second data in the second format, the media renderer being operable to render a first received data based on the data in the third format and to render a second received data based on the data in the fourth format;

predetermining factors to measure a utility of the media delivery network, a factor comprising a media modality quality relating an importance of a media adapter to content of the media source and a type of adaptation of the media adaptor;

defining a utility function based on the predetermined factors by defining a utility equation as
