AVIS: An Adaptive VIdeo Simulation Framework for Scalable Video

Scalable video coding (SVC) features a flexible media representation that enables adaptive streaming as network conditions change. However, existing SVC simulation tools do not support adaptive video transmission. In this paper, we present an Adaptive VIdeo Simulation (AVIS) framework for SVC in network simulator 2 (NS2). The framework includes two new NS2 objects, including AVIS transmitter and receiver, preprocessing and post processing tools that can be used with any SVC encoding. AVIS design provides a flexible and configurable means for supporting a wide range of time-based and traffic-based input parameters for adaptive algorithms. Hence, AVIS represents a unique framework that would speed up the performance evaluation of newly developed adaptive streaming algorithms for SVC.
