US 2003/0081580 A1 · Method and apparatus for a reconfigurable multi-media system

Abstract

A reconfigurable multi-media system, method and device provides monitoring and reconfiguration of a plurality of communication layers of a communications stack to dynamically reconfigure the modulation and coding of software defined radio (SDR). The system includes a software object radio (SWR) library having reconfigurable object specification, design and performance parameters, the SWR is adapted for at least one of transmitting and receiving multi-media content via wireless communication; a controller in communication with the SWR library; a power management device module in communication with said controller; a reconfigurable encoder/decoder in communication with said controller to provide the SWR with dynamic coding information for modulation; a TCP/IP interface in communication with said reconfigurable encoder/decoder and said controller; and an application layer comprising a link layer and a reconfigurable physical layer in communication with each other and said controller, the physical layer adapted for communication with a channel, and the application layer including at least one driver for multi-media delivery. The controller monitors the physical layer and link layer information and the reconfigurable encoder/decoder dynamically reconfigures modulation and coding of multi-media content according to a cross-layer optimization approach.
