Abstract

A server for adaptively rendering a multimedia content stream includes a first interface for connecting the server to a multimedia network server to receive an original multimedia content stream. A second interface connects the server to a client for receiving a rendered multimedia content stream. Processing logic determines rendering parameters responsive to connection parameters related to connection bandwidth between the server and the client. Rendering logic renders the multimedia content stream from the original multimedia content stream responsive to the rendering parameters.
