This module simulates a video-on-demand (VoD) client application that receives video frames over UDP. It is assumed that the transmitted video is encoded using multiple layers according to the Scalable Video Coding (SVC) technique. Hence, the module collects separate statistics (such as throughput and delay) for each layer.
