Content adaptive network aware joint optimization of wireless video transmission

Abstract

A content adaptive, network aware approach for joint optimization of wireless video transmission is presented in this article. The joint system optimization approach has been developed in the framework of the IST PHOENIX project (www.ist-phoenix.org). After a description of the considered cross-layer approach and of the information to be exchanged among the system component blocks, the concept of "JSCC/D controllers" is introduced. Results obtained through the demonstrator realized as proof-of-concept for the described paradigm are then shown, confirming the validity of the described joint optimization approach
