Independence of source and channel coding for progressive image and video data in mobile communications

The work reported here has been funded by the Delft University of Technology DIOC research programme. DIOC programmes are an initiative of the ARTD (" Advisory Council Technology T.U. Delft "), and aim at solving, in a multidisciplinary way, specific technological problems with engineering and social significance. ABSTRACT In this paper we assess the independence of the optimization of source and channel coding parameters. We propose a method to separate the source and channel coding optimization as much as possible while maintaining the possibility of joint optimization. We theoretically derive key parameters that must be passed through an interface between source and channel coding. This separation greatly reduces the complexity of the optimization problem and enhances the flexibility.
