VodUdpClient¶

//
// 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.
//
simple VodUdpClient like IApp
