Scalable Video Coding (SVC) is the latest extension of the famous Advance Video Coding (AVC) standard. Scalability is important and useful because it is dedicated to the transmission of video contents over heterogeneous network conditions and terminals' capabilities. Nevertheless, the multimedia service research community and industry have not been able to fully utilize the entire potential of this video coding standard extension because of the lack of a platform for evaluating the end-to-end transmission of SVC-contents. EvalSVC aims to foster SVC-based applications and research in multimedia services. It is capable of evaluating the end-to-end transmission of SVC bit-streams encoded with enhanced features (spatial, temporal, SNR, and combined scalability). The output results are both objective and subjective metrics of the video transmission. Interfaces with real networks and an overlay simulation platform are presented. Through these interfaces, the transmission performance of different types of SVC scalability and AVC bit-streams can be evaluated easily
