Abstract
A key constraint in mobile communications is the reliance on a battery with a limited energy supply. Efficiently utilizing the available energy is therefore an important design consideration. In this paper we consider a situation where a video sequence is to be compressed and transmitted over a wireless channel. The goal is to limit the amount of distortion in the received video sequence while using the minimum required transmission energy. To accomplish this goal we consider error resilience and concealment techniques, at the source coding level, as well as the dynamic allocation of physical layer communication resources. We jointly consider these approaches in a novel framework. In this setting we formulate an optimization problem that corresponds to minimizing the energy required to transmit a video frame with an acceptable level of distortion. We present methods for solving this problem and other extensions. 1.
