Patent ID: 7016668

Claim:
A reconfigurable multi-media system comprising: a software object radio (SWR) library 130 comprising reconfigurable object specification, design and performance parameters, said SWR adapted for at least one of transmitting and receiving multi-media content via wireless communication; a controller 115 in communication with said SWR library; a power management device module 135 in communication with said controller; a reconfigurable encoder/decoder 140 in communication with said controller to provide the SWR with dynamic coding information for modulation; a TCP/IP interface 145 in communication with said reconfigurable encoder/decoder and said controller; and an application layer 125 comprising a link layer 120 and a reconfigurable physical layer 100 in communication with each other and said controller 115 , the physical layer adapted for communication with a channel 110 , and said application layer including at least one driver for multimedia delivery; wherein the controller 115 monitors the physical layer 100 and link layer 120 information, and the reconfigurable encoder/decoder 140 dynamically reconfigures modulation and coding of multi-media content according to a cross-layer optimization approach in conjunction with the controller from: (a) the physical layer 100 according to channel conditions and device power restrictions; (b) the link layer 120 according to variation in network access delay in a multi-user network; and (c) the application layer 125 according to variation in characteristics of a data stream to be transported.
